Overview
To promote energy saving, The Government of the HKSAR enacted the
Buildings Energy Efficiency Ordinance (Chapter 610) and all new office
building designs need to comply with the Building Energy Code published
by the Electrical and Mechanical Services Department (EMSD). In
addition,
for existing buildings also become mandatory.
However, the coverage of an audit is confined to the landlord’s areas.
Even though some energy saving opportunities (called EMOs) can be
identified through the
, the implementation of the auditor’s
recommendations is not required under the Ordinance.
