22FB.—(1) No owner of any prescribed building shall carry out, or permit or authorise the carrying out of, any major energy-use change to that building, unless the owner has first —
(a) appointed a mechanical engineer to assess the design score for the major energy-use change to the building;
(b) submitted the design score assessed by the mechanical engineer appointed under paragraph (a) to the Commissioner of Building Control for approval, in the prescribed form and manner and accompanied by such documents and fee as may be prescribed; and
(c) obtained the approval of the Commissioner of Building Control for the design score, which approval has not lapsed at the time of commencement of the major energy-use change.
(2) Subject to subsection (5), the Commissioner of Building Control shall not approve the design score in relation to a prescribed building unless the design score meets the prevailing minimum environmental sustainability standard for that building or a building of that class or type.
(3) Upon receiving the submission of a design score relating to a prescribed building for approval under subsection (1), the Commissioner of Building Control may direct the owner of the building in writing —
(a) to comply with such requirements in relation to the major energy-use change as the Commissioner of Building Control may specify so that the design score meets the minimum environmental sustainability standard applicable to the building; and
(b) to re-submit the design score for his approval within such period as may be specified in the direction.
(4) If the direction given by the Commissioner of Building Control under subsection (3) is not complied with within the period specified in that direction, or such further period as may be extended by the Commissioner of Building Control, the application for approval of the design score shall, at the end of that period, be deemed to be disapproved by the Commissioner of Building Control.
(5) The Commissioner of Building Control may, on the application of an owner of a prescribed building in any particular case, modify or waive any requirement in relation to the minimum environmental sustainability standard applicable to the building, subject to such conditions as the Commissioner of Building Control may impose.
(6) The Commissioner of Building Control may approve the design score on the basis of a declaration by the mechanical engineer who assessed the score certifying the correctness of the design score.
(7) A mechanical engineer appointed under subsection (1)(
a) in relation to a prescribed building shall —
(a) design the proposed major energy-use change to the building so that the design score meets the minimum environmental sustainability standard applicable to the building;
(b) assess the design score for the major energy-use change to the building in the manner prescribed; and
(c) provide to the owner of the building —
(i) the design score and the documents on which the design score was assessed;
(ii) a declaration as to whether the design score meets the minimum environmental sustainability standard applicable to the building; and
(iii) such other documents as may be required by the Commissioner of Building Control.
(8) Any owner of a prescribed building who, without reasonable excuse, contravenes subsection (1) shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $100,000 and, in the case of a continuing offence, to a further fine not exceeding $1,000 for every day or part thereof during which the offence continues after conviction.
(9) Any mechanical engineer who —
(a) without reasonable excuse, contravenes subsection (7); or
(b) furnishes any information or makes any statement in relation to the design score, or in any other document required under subsection (7)(c), which he knows or has reason to believe is false, shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $10,000.
