RETRO-COMMISSIONING

Introduction

More than half (approximately 54%) of Hong Kong’s total annual energy end-use is in the form of electricity consumption and buildings take up about 90% of our total electricity consumption. It is imperative to reduce the use of electricity in buildings to help combat climate change. 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, having the highest building density in the world, has around 60% of buildings with an age of over 25 years. The saving potential shall be significant.
