A Detailed Energy Audit for a Commercial Office Building in Hong Kong

An energy audit has been conducted for a commercial office building in Hong Kong. This building is equipped with a large number of electricity sub,meters which greatly facilitated the audit study. In addition, a survey of the energy end-use of tenants has been conducted to obtain information about the lighting and equipment loads in various premises in the building. Besides the audit and survey results, comparisons with consumption of typical buildings in Hong Kong and with computer simulation results for an energy efficient building are presented. From the comparison, the most promising energy efficiency improvement measures have been identified for further in-depth studies.
