Foreword

on our environment. The Government is taking appropriate steps to ensure that green building practices are mainstreamed through a mix of regulations and voluntary schemes. The National Action Plan on Climate Change has, therefore, announced a mission on  sustainable  habitats. In addition, the recently launched ECBC 2007 (Energy Conservation Building Code 2007), the appliance labelling programme of  the  Bureau of Energy Efficiency, and the rating system for appraisal and clearance of large construction projects by the Ministry of Environment and Forests are some of the significant steps to move towards green buildings. Several corporate organizations and institutions have mandated the use of green practices in their new construction. Development of a holistic framework that meets all the regulatory norms and responds to the needs of differing agro-climatic zones in India is felt to be an urgent need. GRIHA (Green Rating for Integrated Habitat Assessment) was developed in response to this need.

Keeping in view  agro-climatic  conditions in India and, in particular, the  preponderance  of non-air-conditioned buildings, the National Rating System – GRIHA –  has  been developed  as a suitable system for  all  kinds of  buildings in different climatic zones of the country. The system, initially developed by TERI asTERI-GRIHA, has been modified to GRIHA as the country’s

National Rating System after incorporating various modifications suggested by a group of architects and experts.

The GRIHA rating system takes into account the provisions of the National Building Code 2005; the Energy Conservation Building Code 2007 announced by BEE (Bureau of Energy Efficiency) and other IS codes.

GRIHA – the National Rating System will evaluate the environmental  performance  of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’. The rating system, based on accepted energy and environmental principles, will seek to strike a balance between established practices and emerging concepts, both national and international.

On a broader scale, this system, along with the activities and processes that lead up to it, will benefit thecommunity at large with improvement in the environment by reducing GHG (greenhouse gas) emissions, improving energy security, and reducing the stress on natural resources.

This book provides a comprehensive understanding of GRIHA, its underlying criteria and the rating procedure. The book also covers best practices that could be followed to achieve desired GRIHA ratings.

1.0  Green buildings: global and local perspective

The construction sector poses a major challenge to the environment. Globally, buildings are responsible for at least 40% of energy use. An estimated 42% of the global water consumption     and 50% of the global consumption of raw materials is consumed by buildings when taking into account the manufacture, construction, and operational period of buildings. In addition, building activities contribute an estimated 50% of the world’s  air pollution, 42% of its greenhouse gases,  50% of all water pollution, 48% of all solid wastes and 50% of all CFCs (chlorofluorocarbons) to the environment.

India too faces the environmental challenges of the construction sector. The gross built-up area added to commercial and residential spaces was about 40.8 million square metres in 2004–05, which is about 1% of annual average constructed floor area around the world and the trends show   a sustained growth of 10% over the coming years. With a near consistent 8% rise in annual energy consumption in the residential and commercial  sectors,  building  energy  consumption  has  seen an increase, from a low 14% in the 1970s to nearly 33% in 2004–05.1 Energy consumption would continue to rise unless suitable actions to improve energy efficiency are taken up immediately.       As per TERI estimates, there is an increased demand of about 5.4 billion units (kWh) of electricity annually for meeting end-use energy requirement for residential and commercial buildings.

Buildings are major consumers of water during construction and operation (for occupants, cooling, and landscaping). Per capita water consumption in 1990 was 2464 m3 per capita per annum, but by 2025 with an expected population of 1.4 billion, it will almost certainly be in the stress category with less than 1700 m3 per capita per annum. In terms of accessibility to water supply, as per the information received from the State Governments of India, as of March 2004, about 93%    of urban population has access to drinking water supply facilities. The coverage figures indicate   only the accessibility, whereas adequacy and equitable distribution and per-capita provision  of these basic services may not be as per the prescribed norms in some cases. For instance, the poor, particularly those living in slums and squatter settlements, are generally deprived of these basic facilities. Similarly, the issue of water supply is critical not only for day to day needsof drinking water but also for agriculture and allied activities.

While we grapple with water shortage, there  is  a  huge  potential  of  meeting  the  resource  gap through treatment of waste water and reuse of the same for various applications. As per          an assessment made by the Central Pollution Control Board (CPCB) on the status of wastewater generation and treatment inClass I cities and Class-II towns during 2003–04, about 26 254 million

1 Construction Industry Development Council, India. India Country Report, 2005–06; Address: 801, Hemkunt Chambers, 89, Nehru Place, New Delhi 110019

litres per day (MLD) (9.51 billion cubic metre (BCM) was generated in 921 Class I cities and Class II cities in India (housing more than 70% of urban population). The waste water treatment capacity developed so far is about 7044 MLD accounting for only 27% of waste water generated in these two classes of urban centres (2.57 BCM/year).

Management of construction and demolition waste and solid waste generated by occupants of buildingpose another major challenge which needs attention. The CPCB has estimated current quantum of solid wastegeneration in India to the tune of 48 million tonnes per annum, out of which 25% of waste accounts forconstruction industry. Management of such high quantum of waste puts enormous pressure on solid wastemanagement system. In addition, about 42 million metric tonnes (MMT) of solid waste is generated daily in theurban areas of the country. Most urban centres lack appropriate segregation, management and treatmentfacilities for solid waste. Currently, municipal solid waste is hardly segregated at source. Mixed waste is being dumped into the depression or earmarked low lying areas in and around the towns. Municipal solid wastecomprises of 30% to 55% of bio-degradable (organic) matter, 20% to 35% inert matter and 5% to 15%recyclables. The organic fraction of municipal solid waste contains bio-degradable matter ranging from 30% to55%, which can be profitably converted into useful products like compost (organic manure), methane gas (used for cooking, heating, lighting, production of energy), and so on.

At macro level, extensive urbanization is leading to uncontrolled ‘heat island’ effect. Vegetation and tree cover give way to urban areas with large expanses of pavements, buildings, and other structures, thus eliminating cooling provided by vegetation through both shade and evapo transpiration. This contributes to the formation of ground-level ozone, which is detrimental to human health. Urban heat island impacts giverise to increased temperatures by up to ten degrees Fahrenheit. This also results in increased demand for air conditioning. Increased air conditioning demands increased generation of electricity which again contributes tothe emission of greenhouse gases. These need to be addressed at settlement (can settlements be deleted-OK todelete) planning level as well as micro planning level during site development and planning for buildings.

As we chart our developmental path, it is important for us to keep our eyes on the environmental damagethat we create. It is extremely important to pause for a while and carry out necessary course correction forbenefit of the Mother Earth and our future generations. It is a well established fact that green buildings offer immense potential to reduce consumption and regenerate resources from waste and renewable sources and offer win-win solution for user, owner and the environment.

1.1  What is a green building?

Buildings have major environmental impacts during their life. Resources such as ground cover, forests, water, and energy are dwindling to give way to buildings. Resource-intensive materials provide structure to a building and landscaping adds beauty to it, in turn using up water and pesticides to maintain it. Energy-consuming systems for lighting, air conditioning, and water heating provide comfort to its occupants. Hi-tech controls add intelligence to ‘inanimate’ buildings so that they can respond to varying conditions, and intelligently monitor and control resource use, security, and usage of fire fighting systems and other such systems in the building. Water, another vital resource for the occupants, gets consumed continuously during building construction and operation. Several building processes and occupant functions generate large amounts of waste, which can be recycled for use or can be reused directly. Buildings are thus one of the major pollutants that affect urban air quality and contribute to climate change. Hence, the need to design a green building, the essence   of which is to address all these issues in an integrated and scientific manner. It is a known fact that  it costs more to design and construct a green building compared to other buildings.However, it is also a proven fact that it costs less to maintain a green building that has tremendous environmental benefits and provides a better place for the occupants to live and work in. Thus, the challenge of a green building is to achieve all its benefits at an affordable cost.

A green building depletes the natural resources to a minimum during its construction and operation. The aim of a green building design is to minimize the demand on non-renewable resources, maximize the utilization efficiency of these resources when in use, and maximize the reuse, recycling, and utilization ofrenewable resources. It maximizes the use of efficient building materials and construction practices; optimizesthe use of on-site sources and sinks by bioclimatic architectural practices; uses minimum energy to poweritself; uses efficient equipment to meet its lighting, air conditioning, and other needs; maximizes the use ofrenewable sources of energy; uses efficient waste and water management practices; and provides comfortable and hygienic indoor working conditions. It is evolved through a design process that requires inputfrom all concerned

– the architect; landscape designer; and the air conditioning, electrical, plumbing, and energy consultants –to work as a team to address all aspects of building and system planning, designing, construction, andoperation. They critically evaluate the impacts of each design decision and arrive at viable design solutions to minimize the negative impacts and enhance the positive impacts on the environment. In sum, the following aspects of a green building design are looked into in an integrated way.

#         Site planning

#         Building envelope design

#         Building system design (HVAC [heating ventilation and air conditioning], lighting, electrical, and waterheating)

#         Integration of renewable energy sources to generate energy on-site

#         Water and waste management

#         Selection of ecologically sustainable materials (with high recycled content, rapidly renewable resourceswith low emission potential, and so on)

#         Indoor environmental quality (maintain indoor thermal and visual comfort and air quality)

1.1.1  Benefits of green building

A green building has lower resource consumption as compared to conventional buildings. The following isthe percentage reduction of various resources in a building and their respective reasons. P Green buildings consume 40% to 60% (depending on the range of measures adopted) lesser electricity as compared toconventional buildings. This is primarily because they rely on passive architectural interventions in the buildingdesign, and high efficiency materials and technologies

in the engineering design of the building.

P Green Buildings also attempt to work towards on-site energy generation through renewable energy utilization to cater to its energy needs. For instance, solar thermal systems can help generate hot-waterand replace the conventional electrical geyser in buildings. Solar PV panels can help generate electricitywhich can reduce the buildings dependence on grid power.

P Green buildings consume 40% to 80% (depending on the range of measures adopted) lesser water ascompared to conventional buildings. By utilizing ultra low-flow fixtures, dual plumbing systems, waste-water recycling systems and rain-water harvesting, green buildings not only reduce their demand for water usebut also look at on-site supply options to cater to its internal and external (landscape) water demands.

P Green buildings generate lesser waste by employing waste management strategies on site. They may alsoemploy waste to energy or waste to resource (like manure, or compost) strategies on site, to minimize theirburden on municipal waste management facilities and land fills.

P Green buildings generate lesser pollution both during construction as well as while in use. Through best-practices such as proper storage of construction materials, barricading of the site to prevent air and noise pollution during construction, proper storage and disposal of waste during construction and operation, and so on, ensures reduced impact on the surrounding environment.

P Green buildings ensure proper safety, health and sanitation facilities for the labourers (during construction) and the occupants (while in use).

P Green buildings restrict the use of high ODP (ozone depleting potential) substances in their systems as well as in finishes.

P Green buildings offer higher image and marketability.

All of these can be achieved at a minimal incremental cost with an estimated payback period of about 3–5 years (excepting renewable energy for power generation).

1.1.2  What is green building rating system?

A green building rating system is an evaluation tool that measures environmental performance of a buildingthrough its life cycle. It usually comprises of a set of criteria covering various parameters related to design,construction and operation of a green building. Each criterion has pre-assigned points and sets performancebenchmarks and goals that are largely quantifiable. A project is awarded points once it fulfils the rating criteria. The points are added up and the final rating of a project is decided. Rating systems call for independent third party evaluation of a project and different processes are put in place to ensure a fair evaluation. Globally,green building rating systems are largely voluntary in nature and have been instrumental in raising awarenessand popularizing green building designs.

1.2  Some of the successful international rating programmes

1.2.1  BREEAM

Building Research Establishment’s Environmental Assessment Method (BREEAM) was developed in the UnitedKingdom in 1990 and is one of the earliest building environmental assessment methods. BREEAM covers a range of building types including—offices, homes, industrial units, retail units, and schools. When a buildingis assessed, points are awarded for each criterion and the points are added for a total score. The overallbuilding performance is awarded a ‘Pass’, ‘Good’, ‘Very Good’ or ‘Excellent’ rating based on the score. BREEAMhas separate criteria/checklist for evaluation of Design and Procurement and for Management and Operation ofbuildings. There is also a set of core credits that can be applied for, in case if the building wishes to go in for‘Core only’ assessment for building performance.

BREEAM major categories of criteria for Design and Procurement include the following:

#         Management (commissioning period and process adopted, monitoring of commissioning, energy use insite activities, waste management, pollution minimization)

#         Health and comfort (adequate ventilation, humidification, presence of controllable blinds, energy efficientlighting, thermal and visual comfort, low noise levels)

#         Energy (sub-metering)

#         Transport (modes of transport to and from site, alternative transport facilities)

#         Water (consumption reduction, metering, leak detection)

#         Materials (asbestos mitigation, storage facilities, reuse of structures, specifications of envelope, use of crushed aggregate and sustainable timber)

#         Land use (previously used land, use of re mediated contaminated land)

#         Ecology (land with low ecological value or minimal change in value, maintaining major ecological systemson the land, minimization of biodiversity impacts)

#         Pollution (leak detection systems, on-site treatment, local or renewable energy sources, light pollutiondesign, avoid use of ozone depleting and global warming substances)

Further details on the system can be obtained from Building Research Establishment Ltd, UK.

1.2.2  CASBEE

Comprehensive Assessment System for Building Environmental Efficiency (CASBEE) was developed in Japan, in 2001. The family of assessment tools is based on the building’s life cycle: pre-design, new construction, existing buildings, and renovation. CASBEE presents a new concept for assessment that distinguishes environmental load from environmental quality and building performance. Under CASBEE there are two spaces, internal and external, divided by the hypothetical boundary, which     is defined by the site boundary and other elements, with two factors related to the two spaces, in which the ‘negative aspects of environmental impact which go beyond the hypothetical enclosed space to the outside (the public property)’ and ‘improving living amenity for the building users’ are considered side by side. Under CASBEE, these two factors are defined below as Q and L, the main assessment categories, and evaluated separately.

Q (Quality): Building Environmental Quality and Performance

Evaluates ‘improvement in living amenity for the building users, within the hypothetical enclosed space (the private property)’.

L (Loadings): Building Environmental Loadings

Evaluates ‘negative aspects of environmental impact which go beyond the hypothetical enclosed space to theoutside (the public property)’.

By relating these two, factors, CASBEE results are presented as a measure of eco-efficiency or BEE (Building Environmental Efficiency). Results are plotted on a graph, with environmental load    on one axis and quality on the other – the best buildings will fall in the section representing lowest environmental load and highest quality. Each criterion is scored from level 1 to level 5, with level 1 defined as meeting minimum requirements, level 3 defined as meeting typical technical and social levels at the time of the assessment, and level 5 representing a high level of achievement.

CASBEE major categories of criteria include

Building Environmental Quality and Performance

#         Indoor environment (noise and acoustics, thermal and visual comfort, and indoor air quality)

#         Quality of services (functionality and usability, amenities, durability and reliability, flexibility and adaptability)

#         Outdoor environment on site (preservation and creation of biotope, townscape and landscape, local characteristic and outdoor amenities)

Building Environmental Loadings

#         Energy (Building thermal load, utilization of natural energy, efficiency in building service systems, and efficient operations)

#         Resources and materials (water conservation, materials of low environmental loads)

#         Off-site environment (air pollution, noise and vibration, odour, sunlight obstruction, light pollution, heat island effect, and load on local infrastructure)

1. 2.3 GBTool

GBTool was developed by the International Framework Committee for the Green Building Challenge, aninternational project that has involved more than 25 countries since 1998. GBTool is designed to be adapted bysponsors to reflect regional conditions and context. It includes criteria in categories such as Site Selection, Project Planning and Development; Environmental Loadings; Energy and Resource Consumption; IndoorEnvironmental Quality; Functionality; Long-Term Performance; and Social and Economic Aspects. Criteria areassessed using scales that are based on local benchmarks of ‘typical’ practice; buildings can score –1 if belowtypical practice or from +1 to +5, representing good to very high performance. All criteria must be attempted.The benchmarks of typical practice and weightings of criteria are set by the sponsoring organization torepresent national, regional, or local codes, practice, context, conditions, and priorities.

GBTool major categories of criteria include the following.

#         Energy consumption is assessed through total use of non-renewable energy (embodied and operational), electrical demand, usage of renewable energy, and commissioning.

#         Resource consumption is assessed through materials use (salvaged, recycled, bio-based and sustainably harvested, locally produced, designed for disassembly, re-use, or recycling) and  water use for irrigation, building systems, and occupant use.

#         Environmental loadings include GHG emissions, other atmospheric emissions, solid wastes,  storm water, waste water, site impacts, and other local and regional impacts.

#         Indoor environmental quality is assessed through indoor air quality, ventilation, temperature and relativehumidity, daylight and illumination, and noise and acoustics.

#         Other criteria include selection of appropriate site (in terms of land use, brown fields, access to transportation and amenities), project planning, urban design (density, mixed uses, compatibility, native species, and wildlife corridors), building controls, flexibility and adaptability, maintenance of operating performance, and a few social and economic measures.

1.2.4  LEED®

Leadership in Energy and Environmental Design (LEED®) was developed and piloted in the US in 1998 as aconsensus-based building rating system based on the use of existing building technology. The rating systemaddresses specific environmental building related impacts using a whole building environmental performanceapproach. The Indian Green Building Council has adapted LEED system and has launched LEED India version for rating of new construction. In addition, Indian Green Building Council (IGBC) has launched several other products for rating of different typologies of buildings including homes, factories, among others. The followingare key components of the LEED system.

#         Sustainable sites (construction related pollution prevention, site development impacts, transportation alternatives, storm water management, heat island effect, and light pollution)

#         Water efficiency (landscaping water use reduction, indoor water use reduction, and waste water management strategies)

#         Energy and atmosphere (commissioning, whole building energy performance optimization, refrigerantmanagement, renewable energy use, and measurement and verification)

#         Materials and resources (recycling collection locations, building reuse, construction waste management, and the purchase of regionally manufactured materials, materials with recycled content, rapidly renewable materials, salvaged materials, and FSC certified wood products)

#         Indoor environmental quality (environmental tobacco smoke control, outdoor air delivery monitoring, increased ventilation, construction indoor air quality, use low emitting materials, source control, and controllability of thermal and lighting systems)

1.2.5  HK–BEAM

The Hong Kong Building Environmental Assessment Method (HK-BEAM)  is  a  voluntary  scheme  first launched in December 1996 HK–BEAM is a performance  based  system  that  takes  holistic view of building performance with emphasis on life cycle impacts. In HK–BEAM, the assessment       is not finalized until  a  building  is  completed  ensuring  that  ‘Green  and  Sustainable’  practices  are implemented through the entire project cycle and the project meets the desired goals and performance. The ‘New Building’ certification system of HK–Beam is also well synchronized with its ‘Existing Building’certification, for example, a new building certified under the HK–BEAM 4/04 and suitably operated and maintained would attain a similar grade under HK–BEAM 5/04 some years later.

HK–BEAM integrates the assessment of many key aspects of building performance embracing

#         Hygiene, health, comfort amenity

#         Land use, site impacts and transport

#         Use of materials, recycling and waste management

#         Water quality, conservation and recycling

#         Energy efficiency, conservation and management

HK–BEAM also exempt building from attempting certain criteria when an issue or past of an assessment is not applicable to particular circumstance or building type.

The overall assessment grade is based on percentage (%) of applicable credits. Given the importance of indoor environment quality, it is necessary to obtain a minimum percentage (%) of credits for IEQ in order to quality for the overall grade.

1.3  Introducing GRIHA

Most of the internationally devised rating systems have been tailored to suit the building industry of thecountry where they were developed. TERI, being deeply committed to every aspect of sustainable development, took upon itself the responsibility of acting as a driving force to popularize green buildings by developing a tool for measuring and rating a building’s environmental performance in the context of India’svaried climate and building practices. This tool, by its qualitative and quantitative assessment criteria, wouldbe able to ‘rate’ a building on the degree of its ‘greenness’. The rating shall evaluate the environmental performance of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’. The rating system, based on accepted energy and environmental principles, seeks to strike a balance between the established practices and emerging concepts, both national and international. The guidelines/criteria appraisal may be revised every three years to take into account the latest scientific developments during    this period. On a broader scale, this system, along with the activities and processes that lead up      to it, will benefit the community at large with the improvement in the environment by reducing  GHG (greenhouse gas) emissions, improving energy security, and reducing the stress on natural resources.

The rating applies to new building stock –  commercial,  institutional,  and  residential  –  of  varied functions. Endorsed by the Ministry of New and Renewable Energy, Government of India      as of November 1 2007, GRIHA is a five star rating system for green buildings which emphasises      on passive solar techniques for optimizing indoor visual and thermal comfort. In order to address energy efficiency, GRIHA encourages optimization of building design to reduce conventional energy demand and further optimize energy performance of the building within specified comfort limits.    A building is assessed on its predicted performance over its entire life cycle from inception through operation.

GRIHA was developed as an indigenous building rating system, particularly to address and assess non-air conditioned or partially air conditioned buildings. GRIHA has been developed to rate commercial, institutional and residential buildings in India emphasizing national environmental concerns, regional climaticconditions, and indigenous solutions.

GRIHA stresses passive solar techniques for optimizing visual and thermal comfort indoors, and encourages the use of refrigeration-based and energy-demanding air conditioning systems only in cases of extreme thermal discomfort.

GRIHA integrates all relevant Indian codes and standards for buildings and acts as a tool to facilitate implementation of the same.

1.4  Introducing TERI

TERI (The Energy and Resources Institute), a dynamic and flexible organization with a global vision and a local focus, was established in 1974. Initially the focus was on documentation and information dissemination. Research activities in the fields of energy, environment, and sustainable development were initiated towards the end of 1982. All these activities were rooted in TERI’s firm conviction that efficient utilization of energy,sustainable use of natural resources, large-scale adoption of renewable energy technologies, and reduction of all forms of waste would move the process of development towards the goal of sustainability.

A unique developing-country institution, TERI is deeply committed to every aspect of sustainable development. From providing environment-friendly solutions to rural energy requirements to helping shape the development of the Indian oil and gas sector; from tackling global climate change issues across continents to helping conserve forests; from advancing solutions to the growing urban transport and air pollution, to promoting energy efficiency in the Indian industry, the emphasis has always been on finding innovative solutions to make the world a better place to live in. Although TERI’s vision is global, its roots are firmly entrenched in the Indian soil. All activities in TERI move from formulating local- and national-level strategies to shaping global solutions to critical energy and environment-related issues. To this end, TERI has established regional centres in Bangalore,  Goa, Guwahati, Kolkata, and Mumbai. It has set up affiliate institutes: TERI– NA (The Energy and Resources Institute, North America) in Washington, DC, USA and TERI–Europe, London, UK; and it also has a presence in Japan, Malaysia and UAE.

TERI fulfils its mandate of sustainable development by advocating the concept of green  buildings, which register minimal impact on the environment. In practicing what it preaches, TERI has constructed its buildings, in Gurgaon, Bangalore and Mukteshwar, along these lines. Resource- and energy-efficient, these habitats are exemplary constructs demonstrating the sustainable implementation of green practices. TERI has also introduced GRIHA, a rating system to adjudge     the ‘greenness’ of buildings, which has now been adopted by the Ministry of New and Renewable energy, Government of India as a national rating system.The TERI buildings include the following.

1.4.1  RETREAT

Resource Efficient TERI Retreat for Environmental Awareness and Training, RETREAT, a residential training facility for executives, is designed to be self-sufficient, and independent of any external power supply. Itconsists of living quarters with 24 single-occupancy rooms and 6 suites complete with conference centre with alarge hall, a dining room, a lounge, recreational facilities, and a library. # The complex has harnessed both traditional and modern means of tapping renewable sources of energy to offer modern amenities such aslighting, air conditioning, cooking, laundry, and so on at substantially reduced costs.

#         The complex saves 40%–50% of energy costs over conventionally designed buildings at an additional investment of about 25%.

#         Twenty-four solar water-heating panels provide up to 2000 litres of hot water every day.

#         The building is powered by a hybrid system comprising of Solar photovoltaic system (with battery back up)and a 100 kW biomass gasifier

Effective insulation, shade provided by trees, and a network of underground earth air tunnels circulating cool subterranean air throughout the residential block ensure that the temperature in the complex remainsmore or less even all year round at 20 °C in winter, 28 °C in the dry summer, and

Figure 3 Green features of RetReat Complex, Gual Pahari, Haryana

30 °C in the monsoon. The system has been augmented by adding chillers for dehumidification and additional cooling during the monsoon.

Specially designed skylights, energy-efficient lights, and a sophisticated system of monitoring and controllingelectricity consumption, light up the complex with less than 10 kilowatts; a comparable conventionally designedstructure would require nearly 28 kilowatts to provide the same level of lighting.

A bed of reed plants (Phragmytes) clarifies 5 cubic metres of waste water from the toilets and kitchen every day; the recycled water is used for irrigation.

1.4.2  TERI University

The TERI University is situated at Plot No. 10, Institutional Area, Vasant Kunj, New Delhi, close to the GrandHotel. An architectural marvel, the campus has been planned to provide a setting that enhances learning,while simultaneously showcasing the concept of green building. Besides passive energy saving architecturaldesigns, the buildings boast of the use of solar energy and an earth-air tunnel to meet part of the air-conditioning requirements.

The campus is equipped with three types of cooling systems, integrated to take advantage of differentinnovative technologies to achieve energy efficiency. They are discussed briefly as under. # Variable refrigerant volume systems (VRV)

#         Earth Air Tunnel (EAT)

#         Thermal storage

The VRV system is a modern air-conditioning system, similar to an efficient version of a split air conditioner.The VRV system is highly efficient under partial load conditions and therefore, has been used in areas withvarying occupancies such as the office block, laboratories, administrative block and recreation and dining areas of the hostel block. It features customized control of individual zones. Depending on the cooling demands of the building, variable refrigerant volumes circulate through the chillers. The VRV system alsoeliminates the requirement of a plant room; piping and ducting for chilled water; and contributes to 15% energysavings as compared to a conventional air conditioning system.

Earth air tunnel system is used for free cooling/heating of the building for a major part of the year. Thistechnology uses the heat sink property of earth to maintain comfortable temperatures inside the building.Supplementary systems have been used for extreme conditions (monsoon). In such a system energy savingsof nearly 50% compared to conventional system can be achieved. At the campus, this system is used forproviding comfort for the rooms in hostel block.

Thermal mass storage is used in the classrooms. It involves storing energy when available and using it when required. In the proposed arrangement, cooling of the thermal mass is done during night (when ambient temperatures are lower). During daytime when ambient temperatures are high, the thermal storage is used as sink for the fresh air requirement.

The campus has an efficient artificial lighting system designed for minimizing the energy consumption without compromising the visual comfort in the building.

The measures contribute to 40% energy savings in comparison to a conventionally designed building.Water saving measures have 25% reduction in the potable water use only by use of efficient fixtures. In addition,reuse of wastewater for irrigation purpose through resource and energy efficient biological processes andrainwater harvesting for aquifer recharge also contribute to efficient water management.

1.4.3  TERI, Bangalore

TERI has provided a unique environmental solution with its model energy-efficient building at Domlur, Bangalore, and affording maximum comfort through minimum use of conventional electricity. Bangalore being in a moderate climate zone of India has comfortable temperature round the year.

The building boasts of an innovative design to make maximum use of the natural resources. It openstowards the northern side facilitating access to glare-free light.

A solar wall towards the south (drain side) of the building directs the flow of the breeze over    the building. This, in turn, creates a negative pressure and pulls fresh air from the north into the building. Air conditioning is fully avoided and the building maintains comfortable conditions round the year.

Optimum use of appropriate building envelope, use of energy-efficient lamps, luminaries, control strategieshave been employed to reduce dependence on artificial means of lighting and to create comfortable conditions.

By creating atrium spaces with skylights, sections of the Centre are designed in such a way that natural daylight enters into the heart of the building, considerably reducing the dependence on artificial lighting. This is supplemented by a skylight roof and energy-efficient artificial lighting. A roof garden has also beendeveloped to reduce heat gain.

Solar water heating meets the hot water requirements of the kitchen and other utilities. A 2-kW peak solar photovoltaic system meets a part of the power requirement. Rainwater harvesting is used to manage water in the complex. The collected water is treated and used for various maintenance purposes, like use in sprinklers for landscape covers. The sections are worked out so as to allow hot air to rise towards the top. Natural ventilation occurs with the air flowing from the ground floor to the terrace because of the open nature of the volumes. The building does not need air conditioning round the year and has minimum lighting requirement during daytime. The annual average energy consumption is only about 30 kWh/sq m.

1.4.4  TERI, Mukteshwar

TERI’s Himalayan centre is located in Latey  Bunga,  Mukteshwar,  2300  metres  above  sea  level. The facility has a residential wing, is addition to conference hall, meeting area, and rest rooms.

The general orientation of the building is south-east, ensuring that all major openings are in line with the sun. In accordance with strategic landscaping principles, trees have been planted on the northern side of the building to provide a buffer against cold winds. The building is thus optimally day lit and receives solar radiation for heating. Furthermore, each suite comes attached with unique solar passive features known as ‘sun-spaces’. These enhance heat gain by day and emit it by night, when it is required. Judiciously planned corridors in front of the habitable spaces dilute the glare of the sunlight, while trapping solar radiation.

Renewable energy systems in the form of photovoltaic solar panels have been integrated into the roof of the utility building and conference hall to meet a portion of the electrical requirements. An effective solar water heating system is in place to meet the hot water requirements of the building’s inhabitants. In the absence of sufficient sunlight, battery banks provide a power back-up for three days. Fibreglass panels in the ceilings and walls act as insulation, preserving heat and improving acoustics.

Despite the ample rainfall in the area, it faces a severe shortage of potable water. As a result, innovatively designed, twin-chambered water tanks are deployed in the harvesting and subsequent filtering of rainwater for human consumption.

1.5  The Ministry of New and Renewable Energy

The Ministry of New and Renewable Energy has been promoting energy efficient / solar buildings in thecountry since its inception in 1982 through wide ranging programmes including research and development, demonstration through construction of pilot projects, development of design tools and supporting capacitybuilding and awareness generation activities. In order to lead by example, the Ministry constructed all buildings at its Solar Energy Centre based on solar passive concepts. Through a study sponsored by MNREto IIT Delhi, classification of six climatic zones were established which has formed the basis of developingdesign strategies for each of these climatic zones. Various concepts, like, earth-air tunnel system, wereevaluated and designing protocols were set under R&D programme of the MNRE. The Ministry providedincentives under its Solar Building Programme to prepare detailed project reports for constructing solar passivebuildings and partial financial assistance was also provided for construction of such buildings. Finding the concept of solar buildings useful, the state governments of Himachal Pradesh, Punjab, Haryana and Nagalandmade it mandatory to construct all new buildings in government and public sector on this concept. A comprehensive and suitable to Indian climate and buildings, National Rating System, called GRIHA, wasdeveloped by MNRE based on the initial work carried out at The Energy and Resources Institute (TERI) and feedback received from group of architects and experts. Currently, MNRE is implementing a Scheme on‘Energy Efficient Solar/Green Buildings’ with the main objective to promote the widespread construction ofenergy efficient solar/green buildings in the country through a combination of financial and promotionalincentives to save a substantial amount of electricity and other fossil fuels apart from having peak loadshavings in cities and towns. To achieve the objectives, the scheme has provisions for (i) providingreimbursement of 90% of the rating-cum- registration fee for buildings rated for their performance under NationalRating System, (ii) providing incentives to architects and consultants to design buildings on Green Architecturalconcepts and get them rated under GRIHA, (iii) providing financial support for promotional activities, (iv)providing incentives to local urban bodies, (v) institution of awards/incentives for green buildings rated 5 star, and(vi) organizing various other activities related to development of web based tools, e-learning modules, and so on. The Ministry is also providing financial support to establish ADaRSH (GRIHA Secretariat) as anindependent autonomous body for the operation of the rating system. With an aim to expedite implementationof the rating system, MNRE has modified the provisions of scheme to exempt first 100 Govt/Public SectorBuildings from paying registration-cum-rating fee in advance

at the time of registration.

In order to develop the training and awareness material and tools, the Ministry is supporting TERI to developdetailed manuals for trainers and evaluators. Web-link tools are also being developed to create awareness generation through Internet. The Ministry is working with CEPT University, Ahmedabad; and IIIT, Hyderabadfor the development of e-learning modules. A ‘Green Pledge’ has also been drafted with an aim to sensitize 100 top corporate about the necessity to adopt green building designs for new buildings. In order to outreachto private architects, MNRE has supported programmes for capacity building and awareness generationthrough Indian Institute of Architects (IIA), Society for Energy Engineers and Managers (SEEM), and CII.Programmes with special focus on SEZs are being organized through CII supported by the Ministry. Adetailed plan to train CPWD engineers and architects has been drawn and is being implemented by ADaRSH(GRIHA secretariat).

The Ministry is also supporting research and development activities, and has sanctioned a project recently to establish solar calorimeter at CEPT University for characterization of glazings for building applications.

1.6  Development of GRIHA — the national rating system

GRIHA, the national green building rating system, was developed by TERI after a thorough study andunderstanding of the current internationally accepted green building rating systems and the prevailingbuilding practices in India. The rating system was developed by the Centre for Research on Sustainable BuildingScience (CRSBS), TERI . CRSBS has been set up in TERI to facilitate development and mainstreaming ofsustainable buildings, to improve performance levels of existing buildings, and raise awareness on sustainable buildings. CRSBS comprising architects, planners, engineers, and environmental specialists has been offering environmental design solutions for habitat and buildings of various complexities and functionsfor nearly two decades. With extensive experience in the field of sustainable and green building design and operation, the team came up with the GRIHA framework in 2005. Prior to coming up with the indigenous ratingsystem for India, the team has extensively researched on several international rating systems (some of themhave been listed above). The team has effectively utilized the several multidisciplinary strengths and experiences of their colleagues at TERI to arrive at the tool that addresses crosscutting issues in the design, development, and operation of a green building.

The primary objective of the rating system is to help design green buildings and, in turn, help evaluate the‘greenness’ of buildings. The rating system follows best practices along with national/ international codes thatare applicable to the green design of buildings.

The green building rating system devised by TERI is a voluntary scheme. It has derived useful inputs fromthe building codes/guidelines being developed by the BEE (Bureau of Energy Efficiency), the MNRE (Ministry ofNew and Renewable Energy), MoEF (Ministry of Environment and Forests), and the BIS (Bureau of IndianStandards). The rating system aims to achieve efficient resource utilization and to enhance resource efficiencyand quality of life in buildings.

GRIHA has been adopted as a NRS (national rating system) under the MNRE, Government of India, as of 1 November 2007. The MNRE has set up a technical advisory committee comprising of eminentprofessionals.

1.6.1  Operationalization of GRIHA — the national rating system

National Advisory Council

A NAC (National Advisory Council) has been constituted by the MNRE and is convened by the Advisor of the Ministry. It comprises eminent architects, senior government officials from the Central Ministry, the BEE, the Central Public Works Department, and select state nodal agencies; representatives from the IT sector, real estate sector and developers; and representatives from ADaRSH (GRIHA secretariat) and TERI. The NAC is chaired by the Secretary, MNRE, and co-chaired by the Dr R K Pachauri, Director-General, TERI.

The NAC provides advice and direction to the NRS and is the interface between the MNRE and ADaRSH (GRIHA secretariat). Its broad functions are as listed below.

#         Guide the administrative structure for GRIHA

#         Decide a fee structure

#         Endorse the rating

#         Recommend incentives and awards by the Government of India/state governments

#         Endorse modifications/upgrades periodically

Technical Advisory Committee

A TAC (Technical Advisory Committee) has been constituted by the MNRE for providing technical advice tothe GRIHA team on modifications and upgradation of the GRIHA framework. The technical advisory teamcomprises eminent architects and experts well versed with design and construction of green buildings.

The Ministry has incentivised the NRS (current incentive scheme is available in Annexure 1 with a view topromote large-scale design and construction of green buildings in the country.

The basic features

At present, the system has been developed as ‘design and evaluate’ new buildings (buildings that  are still at the inception stages). A building is assessed based on its predicted performance over its entire life cycle — from inception to operation. The stages of the life cycle that have been identified for evaluation are pre-construction, building design and construction, and building O&M (operation and maintenance). The issues that are addressed in these stages are as follows.

#         Pre-construction stage (intra- and inter-site issues)

#         Building planning and construction stages (issues of resource conservation and reduction in resourcedemand, resource utilization efficiency, resource recovery and reuse, and provisions for occupant healthand well-being). The prime resources that are considered in this section are land, water, energy, air, andgreen cover.

#         Building O&M stage (issues of O&M of building systems and processes, monitoring and recording ofconsumption, and occupant health and well-being, and also issues that affect the global and localenvironment).

1.6.2  How to get your building rated?

All buildings, except for industrial complexes, which are in the design stage, are eligible for certification under the GRIHA system. Buildings include offices, spaces, institutional buildings, hotels, hospital buildings, health care facilities, housing complexes.

Registration

#         A project has to be registered with ADaRSH (GRIHA secretariat) by filling in an online registration formavailable on the GRIHA website (www.grihaindia.org)

#         Registration cost details are available on the Web. Registration should preferably be done at the beginning of a project, as there are several issues that need to be addressed at the pre-design stage.

#         The registration process includes access to the essential information related to rating, application form, list of submissions, score points, and the weightage system, and one day training for the registeredprojects.

During the training session, the following areas will be covered.

#         Overview of the green building design

#         Explanation of the rating system and criteria and points related to rating

#         Online access to the rating tool

#         Documentation process through use of online forms

#         Evaluation process

GRIHA is supported by a complete web based on line document submission and evaluation system. The following process explains in details the use of the GRIHA rating.

Tool

Using the Tool

The GRIHA evaluation tool has the following capabilities.

#         It facilitates online registration of projects

#         It facilitates online submission of compliance forms for attempted criteria

#         The GRIHA rating coordinator from client side is able to control inputs from all consultants who are responsible for documentation

#         Online evaluation by third party evaluators

#         It provides a ‘Project Summary Sheet’ that displays a summary of all the criteria attempted and achieved and their status

#         Easy to use calculators for criteria that require calculations to be carried out

step 1

Building owner/architect/consultants/developers keen on getting their projects registered and  rated under the GRIHA system, are first required to express interest of doing so, by filling in the project registration form with project details and submit to ADaRSH (GRIHA secretariat). ADaRSH (GRIHA secretariat) shall evaluate the project to judge its applicability for rating. The secretariat shall communicate to the client on its applicability of rating.

Once the project is cleared by ADaRSH (GRIHA secretariat) for registration, the client shall register the project formally with ADaRSH by paying the applicable fees (one time, non refundable).

step 2

On successful registration of the project with ADaRSH (GRIHA secretariat), the secretariat staff along with TERI professionals shall conduct a one day training programme to familiarize the client/design/consultant/contractor team with all criteria of GRIHA and the procedure for filling the forms. On   the day of the training, the client (coordinator from the client side) shall be given formal access to the web portal for online submission of GRIHA compliance forms. An independent and exclusive project account is created on registration of a project and the coordinator from the client side is provided with a unique user ID andpassword

#         The coordinator has to login to the web portal for access to the main project page.

#         The coordinator is the focal point for a project and has access to the project details, project summary sheet, the consultants’ work, and the first volume of GRIHA manual.

step 3 select criteria

#         After reading the manual, the client and design team shall decide on the criteria that the project attempts toaccomplish. All mandatory criteria have to be attempted and fulfilled to qualify for rating.

step 4 Create team of consultants who shall fill the templates/calculators for attempted criteria

#         The coordinator has to create a team of consultants who shall fill in the compliance documents/ donecessary calculations for the chosen criteria. To do so, go to ‘Add Consultants’.

#         In order to enable the consultants to access their project accounts, the coordinator must enter their details in the specific fields. Editing or additions are allowed at a later date. Any such change has to be informed to ADaRSH (GRIHA secretariat).

step 5 assign criteria

#         Green design and rating involves engagement of consultants from multidisciplinary back ground (landscape architect, energy consultant, mechanical, electrical and plumbing consultants, contractors and architect). Thus multiple consultants shall be responsible for fulfilment of compliance under respectiveGRIHA criteria, for example, Criteria 13 compliance is under ambit of the architect and energy consultant whereas compliance under Criteria 2 is responsibility of landscape architect, architect and the projectmanager. Hence the compliance templates subsequently get filled in by respective consultants. Thus it isimportant that while the coordinator has overall control of the entire documentation process, individualconsultants are able to upload their respective compliance documents for review by the coordinator.

#         The coordinator thus assigns respective criteria to various consultants who shall be responsible foruploading the compliance documents under their respective purview.

#         The consultants shall then be required to fill up the forms of the criteria assigned to them and on behalf of the consultants the coordinator can also fill the forms.

#         Predefined templates are another feature of this tool. These are structured formats for providing certain information for a particular criterion.

#         There are online calculators available for a particular criterion, for performing any criteria related compliance calculation, with ease.

Instructions for consultants

gaining access

#         In order to access the project accounts, the system shall provide the consultant with unique User ID andpassword once the coordinator has filled in the consultant’s details for his/her project. Any editing oradditions to be made at a later date can be done so by clicking on the appropriate button. Any such changeshave to be forwarded to ADaRSH (GRIHA secretariat).

#         Once logged in, the following page will appear.

The consultant shall be able to access the compliance pages for the criteria that have been assigned to him/herby the coordinator and shall be able to fill in requisite information and upload compliance documents for the respective criteria.

step 6 Project details and project summary sheet

#         The ‘Project Details’ is a page that gives an overall view of all the criteria and their current status. The coordinator can monitor and track the progress of the project through this page and the project summarysheet.

#         The consultant can view in detail and update only those criteria that they have been assigned.

#         They will then be able to upload the compliance documents to the GRIHA webportal.

#         Once all the compliance documents for the attempted criteria are submitted, the summary sheet is ready for onward submission to ADaRSH (GRIHA secretariat) for evaluation. All compliance documents related to mandatory criteria need to be submitted in addition to the compliance documents of the attempted optional criteria.(the fields for the attempted optional criteria shall be activated by the coordinator during project registration).

#         Submission of the summary sheet can be done by the coordinator only after all compliance documents related to all attempted criteria are filled. If the coordinator attempts to submit the summary sheet withoutfully completing it, he/she shall receive an error message and the erroneous areas shall be highlighted. 

#         The files should be saved after filling the forms. The calculation sheets do not have a save button, this is because the texts are automatically saved as each set of calculations are completed.

#         Folders are permitted to be uploaded if multiple files need to be uploaded for the same compliance requirement (maximum file size of 6 MB)

#         The manual can be referred to for technical details, examples and recommendations.

1.7  GRIHA evaluation process

The buildings shall be evaluated and rated in a three-tier process. The process that would be followed has been explained previously.

The GRIHA team shall first review the mandatory criteria and reject a project in the event of non-compliance with such criteria. The team shall then check the documentation submitted for the optional criteria.The checking is done by the GRIHA team to ensure that all templates and drawings are filled-in and to ensure that the documentation is complete in all respects (for the attempted criteria). All documents shall be checkedand vetted through the appraisal process as outlined by GRIHA. The GRIHA team compiles the firstevaluation report and sends to the client. The client is then required to resubmit details as requested for by theSecretariat in the first evaluation report.

The documentation shall now be sent to the GRIHA evaluators comprising of renowned sector experts from landscape architecture, lighting and HVAC design, renewable energy,  water  and  waste management, and building materials. The evaluators shall vet the documentation and independently review the documents for the award of points. The evaluator shall award provisional points (if documentation is in order as per his/her evaluation) and also comment on specific criteria, if need be. The evaluation report shall be sent to the project proponent to review the same and, if desired, take steps to increase the score. The report shall elaborate on the results of the evaluation committee along with its comments. The report shall also list thecriteria for which the documentation is incomplete/inadequate/inconsistent, detailing all the required information. The client shall then be given one month to resubmit the document with necessary modifications. The resubmitted report should comprise only of additional documents/information desired in the evaluation report, which shall again be put through the vetting process as described above. The evaluation committee shall then award the final score, which shall be presented to an advisory committee comprising of eminent personalities and renowned professionals in the field for approval and award of rating. Provisional rating is awarded that is converted to final confirmed rated on meeting compliance as per Criterion 32. The rating shall be valid for a period of five years from the date of commissioning of the building. GRIHA reserves the right to undertake a random audit of any criteria for which points have beenawarded.

1.7.1  Modifications to GRIHA

Over the process of rating various projects registered for GRIHA rating, ADaRSH (GRIHA secretariat) carried out a realistic assessment of applicability of GRIHA criteria to various projects. After carrying out this exercise it was recognized that some criteria in the current GRIHA framework may not apply to a particular project due to technical constraints that are specific to the particular project (for example the criteria related to tree preservation and compensatory forestation may not apply to a site that is devoid of trees).

It was also recognized that relative weightage of points within the current framework needs to be reassessed so that green interventions in a project are given points based on its relative advantage to a project. This resulted in modifications to the GRIHA document which have been mentioned below. Criteria have been classified as ‘Applicable/Selectively-Applicable’. Certain mandatory clauses have been modified/removed based on the applicability /selective-applicability of the criterion.

1.7.2  Scoring method and award of rating

#         The registration form shall request details of top soil, tree cover, hot water requirement, waste water generation, organic solid waste generated .

#         The selectively applicable criteria cannot be attempted by projects that do not meet the threshold values for the selectively applicable criteria.

#         The project shall be rated on applicable criteria only and shall be given percentage scoring for example, aproject scoring 81% out of applicable points shall qualify for a 4 star rating.

#         The information will be provided to ADaRSH (GRIHA secretariat) by the applicant and the Secretariat willdecide the points which are applicable or inapplicable for the particular project.

1.8  Scoring points under GRIHA

GRIHA is a guiding and performance-oriented system where points are earned for meeting the design andperformance intent of the criteria. Each criterion has points assigned to it. It means that a project intending to qualify have to meet with each criterion and earn points. Compliances, as specified in the relevant criterion, have to be submitted in the prescribed format. While the intent of some of the criteria is self-validating in nature, there are others (for example energy consumption, thermal and visual comfort, noise control criteria,and indoor pollution levels) which need to be validated on-site through performance monitoring. The points related to these criteria (specified under the relevant sections) are awarded provisionally while certifying and areconverted to firm points through monitoring, validation, and documents/photographs to support the award of point.

The set of 34 criteria of GRIHA shall be broadly classified into two categories – applicable and selectively applicable.

The applicable criteria has two further sub categories – mandatory  and  optional/non mandatory.

1.8.1  Selectively applicable criteria

These are the criteria that may not apply to a project due to technical constraints or due to the fact that its application may not add sufficient environmental benefit in the rating scale. The registered project shall notapply for this/these criteria and all the selectively applicable criteria shall be decided at registration stage. The registration form shall be expanded to ensure that requisite details are obtained to enable ADaRSH to decide on applicability of these criteria for the project. These criteria and corresponding non applicability conditions are as follows.

The Common Wealth Games 2010 is being scheduled to be held in the capital city of New Delhi. The games villageshall accommodate the players during the games and shall be occupied by individual private homeowners after thegames. A 47.3 hectare (118 acre) picturesque site has been selected on the banks of holy river Yamuna for thepurpose of construction of the games village. The project site is within the immediate vicinity of heritage monuments and historical landmarks, combined with dense green natural covers on the sides.

2.1.1  Site and landscape

The proposed development consists of 4000 bedrooms spread across 34 towers varying in heights (such as; 7 storeys to 9 storeys high). The proposed apartment’s blocks are arranged in site in a way so as to create visual links with heritage sites in the vicinity. The topsoil of the entire excavated site has been collected and stored separately and special measures have been taken for soil stabilization, such as- stockpiling, mulching, and so on. Pervious paving has been provided extensively in the     site . All the service lines and utility corridors on the site are well aggregated and ensure minimum disruption during future maintenance work.

2.1.2  Health and well-being

The sanitation/safety facilities for the construction workers are provided as per National Building Code 2005. These include provision of clean and hygienic accommodation, toilet facilities, purified drinking water, general store, a subsidized canteen, medical facilities, day care centre and onsite safety equipment, and so on. Significant measures have been taken to reduce air pollution during construction, such as – site roads areregularly sprayed with water; wheels of all vehicles are washed, and so on.

2.1.3  Water

2.1.4  Building design and energy

The building design has also included the existing site features, such as, the visual linkages with historicalmonuments, solar geometry, and so on. Due to high density planning requirements, the design did not permit optimum orientation for all apartment blocks. As a result, the apartment blocks have equal exposure towards allcardinal directions. However, the critical facades are shaded and have high performance glazing to negate impact of direct incident radiation. The buildings are fully compliant with the Energy Conservation Building Code 2007. Several energy efficiency measures such as roof insulation, high performance glazing, energy efficient lighting andvariable refrigerant volume (VRV) based air conditioning system have been provided to reduce the energy consumption of the apartments significantly.

2.1.5  Renewable energy

Solar photo voltaic system is proposed to meet the 10% of total energy requirements for internal lighting. 31% of outdoor lighting is provided through solar energy. Solar hot water systems are provided to meet part of water heating needs.

Green Building Design and Certification Environmental Design Solution

One Earth is Suzlon’s corporate headquarters office which is coming up in Pune, India. The project, in keeping up with the spirit of the parent company, attempts to showcase itself as a building project with minimal impact on the environment. The complex consists of an office block and a corporate learning centre. The buildings are positioned on a site area of 45 392 sq.m. The total built-up area is 70 865 sq.m. The project is registered for green building certification under GRIHA. There are various salient features which enable it to become an iconic green building.

One of the first steps taken in the project was to ensure that the architectural aspects of design are well taken care of. Passive design strategies help in ensuring that visual and thermal comfort is maintained within the building with minimum interventions of technologies. The orientation of the blocks is such that the majority of the building’s facades face north, south, north-west and south- east. This enables adequate day lighting and glare control. Glazing on the first and second floors has been shaded from direct solar radiation using louvers. These also act as important design elements of the building and give it a visual identity. Architectural design of the office block is such that various extrusions on various floors shade portions of the building. Therefore, the building is partly self-shaded. In order to create an interesting office atmosphere, break-out spaces have been created in the form of small terraces which have been interspersed all over the office block.

In order to minimize disturbance on site and to ensure easy maintenance, various utility corridors have been provided coupled with the roads and pathways on site. This ensures minimum site disruption post-occupancy.

High efficiency mechanical systems in the building ensure that the energy consumption of the building issignificantly reduced. All desks are equipped with LED lights for task lighting which are governed by motionsensors. So they turn on only when people are seated on their seats. This reduces lighting load to 0.8 W/sq.ft.Extremely high efficiency HVAC systems have been chosen. The HVAC system has various components like pre-cooling of fresh air heat recovery/exchanger mechanisms to minimize energy consumption in HVAC. Overall, thecomplex has managed to reduce its energy consumption by 47% below the GRIHA criterion 14 benchmark figures.

Once the energy performance index of the building was reduced, renewable energy systems       in the form of solar PV and windmills were installed to generate approximately 250 000 units of electricity through renewable sources annually. The project has an installed 13.44 kWp of solar PV and 18 windmills with power capacity of 4.75 kW each.

The project has taken drastic steps in order to reduce its water consumption as well. Use of low- flow fixturesthroughout the complex has ensures that the building requires 65% less water than conventional buildings for sanitary purposes. By planting only native trees and shrubs and using high efficiency sprinkler and drip irrigationsystems, the complex has reduced its landscape water requirement by about 50%. Over 55% of the water in thebuilding is recycled and reused within the complex.

The intent of making a green building is also reflected in various materials used in the structural systems and ininteriors. Use of Post Tension slabs help in reducing concrete requirement in slabs and beams by 37%. Use of PT structural system has helped reduce the requirement of structural steel by almost 50%. Use of Siporex blocks gives the walls of the buildings good insulation while simultaneously using waste material like fly-ash. Majority ofthe materials used for interior application have high recycled content and are low-energy materials.

Overall, the One Earth complex has adopted very high standards for energy and water management which is reflected in their projected energy and water savings. The One Earth complex has taken strong steps to minimizeits environmental impact at various levels while simultaneously projecting a very contemporary feel to the buildingsand spaces, thereby proving the point that green buildings can be as aesthetically pleasing as any conventional building and yet are able to have minimal negative impact on environment.

Centre for Environmental Science and Engineering Building at IIT, Kanpur has been taken as an example to illustrate how the building attempted various GRIHA criteria to make it into a green building.

2.3.1  Sustainable site planning

In order to minimize impact of site development on the environment and surroundings, several   best practice guidelines were adopted like demarcation of site for construction, installation dust screen around the disturbed area to prevent air pollution and spillage to undisturbed site area. Top soil was excavated, stored and preserved outside the disturbed construction site. Erosion control systems were adopted and several trees on site were protected. To increase the perviousness of site and to reduce heat island effect caused due to hard paving around the building, total paving around the building was restricted to 17%, and more than 50% of the paving is either pervious or shaded   by trees. Irrigation water demand has been reduced by more than 50% in comparison to GRIHA benchmark. Adequate health and safety measures related to construction were taken.

2.3.2  Water conservation

There are two ways of conserving water during post construction and after the building is occupied. One is landscapewater demand and second is building water demand. In this building, reduction in landscape water demand bymore than 50% was achieved by use of minimum grass/lawn area, maximum green area under native vegetationand native trees. Low flow plumbing fixtures are used in the building resulting in reduced water consumption fromGRIHA’s benchmark in this building by 62%.Waste water is treated and reused for irrigation. Rain water harvestinghas been designed.

2.3.3    Conservation and efficient utilization of resource: energy

Maximum points weightage in GRIHA is given for energy conservation. The criteria and commitment for energyconservation could be divided into three parts.

3. Efficient window design by selecting efficient glazing, external shading to reduce solar heat   gain but at the same time achieve glare free natural daylight inside all the laboratory spaces of the building.
4. Roof shaded by bamboo trellis and green cover to reduce external solar heat gains from the roof.

1. Common circulation areas are natural day lit and naturally ventilated through integration of skylights andventilators.
2. Water cooled chiller selected that complies with the efficiency recommended by the Energy Conservation Building code.
3. Variable Frequency Drive installed in the Air Handling Units (AHUs).
4. Low energy strategies such as replacement of water cooler by water body to cool the condenser water loop, integration of thermal energy storage and earth air tunnels enabled reduction in chiller capacity.
5. Integration of energy efficient lighting design that complies to the recommendations of ECBC.
6. Integration of daylight with artificial lighting.
7. Optimized architectural design and integration of energy efficient fixtures has resulted in the reduction inannual energy consumption by 41% from GRIHA’s benchmark.

Energy: embodied and construction

GRIHA encourages replacement of high energy intensive materials with low energy intensive materials, to utilize regionally available materials, materials which use low energy in their manufacturing process. Following are the measures incorporated at CESE building, IIT, Kanpur:

1. Portland Pozzolona Cement (PPC) with fly-ash content is used in plaster and masonry mortar.
2. Wood for doors is procured from commercially managed forests. Modular furniture made from particle board is used for interiors.

Energy: renewable energy utilization

Following are the measures incorporated at CESE building, IIT, Kanpur to integrate renewable sources of energy with the building:

1. Renewable energy from photovoltaic panels provide annual energy requirements equivalent to 30% of internallighting connected load.
2. Hot water demand is met by solar hot water system.

Sustainable site planning

The process of site selection for sustainable development involves identifying and analysing the site with respect to the sustainable building design criteria. The development of the site for building purposes requires disruption and interventions. The most sustainable and environment-sensitive development is one that entails minimal site disturbance. Thus, resource conservation in a given site is of prime importance. The criteria for getting points under this head have been elaborated below. The resource efficiency measures are aimed at applying appropriate site planning techniques, concepts and design utilization of site resources, minimize on-site vehicular pollution, enhance energy efficiency of site lighting, and enhance functional efficiency of the utility lines.

Annex

Guidelines for Implementation of Energy efficient solar/ green building Programme

Background

Energy efficient solar buildings are constructed based on the techniques of solar passive design with a view to provide comfortable living and working conditions, both in winter and in summer. These buildings can be integrated with renewable energy and energy conservation devices and systems and can save over 30 to 40 % of conventional energy that is used for lighting, cooling or heating. Such buildings have been tried out  in a few States as a result of the initiatives taken by the Ministry. Finding the concept  of solar buildings useful, the state governments of Himachal Pradesh, Punjab, Haryana and Nagaland have already made it mandatory to construct all new buildings in government & public sectors on this concept. Necessary G.O.s have been issued and  the development authorities have been asked to approve building plans for construction only if the designs incorporating solar passive features are certified by approved architects or the experts. Over 40 experts/architects are presently involved in the country in practicing energy efficient solar buildings. Bureau of Energy Efficiency (BEE) have recently introduced Energy Conservation Building Code (ECBC) which includes energy efficient design features. National Building Codes have also been developed by the Bureau of Indian Standards (BIS) which incorporates some of the concepts of energy efficient solar buildings. Sufficient literature/ publications are also available for design of such buildings.

Efforts are now being made to construct Green Buildings all over the country which not only take care of energy conservation but also look into water and waste management, environmental impact, minimum destruction of natural resources and various other aspects in an integrated way. Building Rating Systems have been quite effective in raising awareness and popularizing energy efficient and green building design. Most of the internationally devised rating systems have been tailored to suit the building sector of the country where they were developed. In India, a US based LEED (Leadership in Energy and Environmental Design) Rating System is under promotion by CII-Godrej Green Business Center (GBC) which is more on energy efficiency measures in AC Buildings. A couple of other Rating systems suitable for Indian conditions e.g. TERI-GRIHA and Eco-Housing System have also been developed by TERI and Pune Municipal Corporation respectively and are under promotion in the country.

Keeping in view our climatic conditions, and in particular the construction of non-AC buildings, a National Rating System – GRIHA (Details available at MNRE website: www.mnre.gov.in) has been developed which is suitable for all types of buildings in different climatic zones of the country. The Rating System was initially conceived and developed by The Energy & Resources Institute, TERI. It has been modified as a National Rating System after incorporating various suggestions by a group of architects and experts. It takes into account the provisions of the National Building Code 2005, the Energy Conservation Building Code 2007 and other IS codes, local bye-laws, etc. Through various qualitative and quantitative assessment criteria, GRIHA would be able to ‘rate’ a building on the degree of its ‘greenness’. It will operate on a 100 point marking system with 70 to 80 points to be obtained for 3 star rated buildings and 81-90 points for 4 star rated buildings. The rating would be applied to different types of new and existing buildings, whether commercial, institutional or residential.

A Memorandum of Understanding has been entered into between the Ministry and TERI towards development and operationalisation of the National Rating System ‘GRIHA’ for Green Buildings. A National Advisory Council (NAC) has been constituted to provide advice and directions to the National Rating System. A Technical Advisory Committee (TAC) has also been constituted to provide technical oversight towards modifications and constant up-gradation of the GRIHA framework. GRIHA will be operated through GRIHA secretariat which will be hosted by TERI. It is understood that large scale promotion of GRIHA will help in getting the new buildings constructed on the concepts of Green Building design suitable for Indian conditions.

Financial Provisions

A        GRIHA Secretariat

GRIHA Secretariat will act as an independent autonomous body. It will be registered by TERI under Society’s Act. A seed funding of upto Rs, 1.00 crore will be made available to the Society for its establishment and infrastructure facility as non recurring grant based on the proposal received from TERI with details of the budget required. However, till the society is formed by TERI the Secretariat will function from the office of TERI at Delhi.

B. Buildings rated under National Rating System -GRIHA

The scheme is presently confined to commercial and institutional building including housing complexes with minimum built area of around 2500 sq.m. All the houses in a complex will me considered as single project individual houses are not covered in the Scheme.

• Registration –cum-Rating Fee

90% of the fee as given below for projects rated 3 star having built area up to 5000 sq. m. and for projects rated 4 star having built area above 5000 sq. m. will be reimbursed by MNRE

Owners of buildings under design and construction, interested to be rated under GRIHA will get their buildings registered with GRIHA Secretariat as per the procedure given at GRIHA/ MNRE Website. Registration-Cum-Rating Fee for the projects registered under GRIHA will be as per below which will be paid to GRIHA Secretariat by the owners at the time of registration.

Release of Registration-cum-Rating Fee to the owners will be made by MNRE on reimbursement basis through GRIHA Secretariat after validation of Star Rating Post

-  Construction by the National Advisory Council.

• Incentive to Architects/ Design Consultants

To encourage Architects and consultants to design buildings on Green Architectural concepts and get them rated under GRIHA, and incentive as per below will be available from MNRE.

-      Rs. 2.50 lakhs for projects upto 5000 sq.m. built-up area with minimum  3 star rating
