Benefit from effect of the Building Energy Efficiency Ordinance (BEEO), buildings built in recent years, both on design and installation, had already fulfilled various energy saving requirements. However, even those newly built buildings, which have the first commissioning process during handover, may not perform as expected due to various reasons, including deviation between design and actual operation, change of usage, behavioural change of occupants,etc. All those reasons will cause the building not to perform at its highest efficiency. Especially for Hong Kong, China, having the highest building density in the world, the saving potential shall be significant.
