Energy saving by realistic design data for commercial buildings in Hong Kong

Oversized equipment is one of the key factors for pour energy performance of commercial buildings in Hong Kong. Similar situations exist also in many buildings in different parts of the world. The use of realistic design criteria has been identified as an effective method lo reduce the equipment oversizing problem. A set of realistic design criteria for lighting power density, occupation density, and appliancesʹ load-intensity for various types of premises have been established based on data obtained in walk-through surveys of energy end-uses in 31 Hong Kong office buildings. Potential electricity savings through the use of realistic design criteria were estimated to be 6-22% of the electricity consumption of Hung Kong, which corresponds to an annual cost of HK$12.2-44.7 billion.
