• Greenery will help reduce the heat island effect and provide better roof insulation which helps reduce the cooling load
and energy consumption of air-conditioning.
• Zone division can enhance the efficiency of operations in the shopping malls. Reducing unnecessary and non-
functional areas can lower the consumption of energy required for air-conditioning and lighting.
• Different zones with different operational hours avoid the excessive use of air-conditioning and lighting.
• Using materials that do not give off any toxic gas or contain harmful substances will help provide a healthier indoor
environment for shoppers and reduce the cost of eliminating them from the air-conditioning system.
1.1.6 Energy consumption
Energy consumption for shopping malls in Hong Kong is about 640kWh/m
2
/year. It is relatively high when compared with
other types of buildings.

Figure 3 shows the energy consumption for retail outlets and restaurants
in Hong Kong. The main sources of energy demand in shopping malls can be
categorised as follows:
• Space Conditioning – Cooling for shops, foyers, arcades, etc.
• Lighting – Interior lighting, exterior lighting, decorative lighting, etc.
• Food and Beverage – Cooking, hot water for steaming,
refrigeration for freezing, etc.
Among the central services operated by landlords, the cooling plant for space
conditioning and lighting form the major energy load. To trim down the energy
consumption and the electricity bills, attention should be given to these areas.
