Building Control Act (Chapter 29).

This Act aims to consolidate the law relating to buildings, and for matters connected therewith; including the outline of protocol around energy use change of a building, and the requirements for energy audits on cooling systems in buildings.
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. 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. The Commissioner of Building Control may require an audit to be carried out as to whether the cooling system of the building meets the prescribed energy efficiency standard applicable to such cooling system.
