The Government aims to achieve electricity savings of 15.0% by FY2020 from our baseline electricity consumption in FY2013. Thus far, agencies have committed electricity saving measures that will collectively lead to 15.2% electricity savings by FY2020. These include “hardware” improvements, such as replacing or upgrading air-conditioning systems and lightings, and “software” actions, like promoting organisational habits that minimise electricity consumption. [...] All new public sector buildings will attain the Green Mark Platinum standard. We will also aim to have existing buildings attain at least the Green Mark Gold standard. [...] The annual energy savings from the Government’s committed measures amount to 290 GWh.

Retrofit existing chiller plants to achieve higher energy efficiency (5.3% savings). Replace existing fluorescent tubes and bulbs with more energy efficient ones (3.8% savings). Replace aging unitary systems with more energy efficient models such as those certified with 3-tick rating and above under NEA’s MELS (3.0% savings). Optimise mechanical ventilation fans, Air Handling Units (AHUs), and data centre operations. Practise energy conservation habits, such as raising the indoor temperature setting and switching off computers and lights when not in use (2.0% savings). Other measures include upgrades of equipment such as lifts, escalators, and other appliances (1.0% savings).
