The Codes specify basic energy efficiency standards for four major types of buildings services installations – air-conditioning, electrical, lift and escalators, and lighting installations.
New public and private buildings covered by the Ordinance need to declare at the design and occupation approval stages that relevant requirements have been met. Buildings services installations at new buildings under the coverage of the Ordinance are required to comply with the Codes at all times.
Existing buildings are also required to enhance energy efficiency when undergoing major retrofitting works. The common areas of commercial buildings and commercial portions of composite buildings are further required to carry out energy audits once every ten years. The results of energy audits should be exhibited in a conspicuous position at the main entrance of the buildings.
