Supermarkets
Compared with general retail shops, the identifying features of supermarkets include:
Large leasing areas
Longer business hours
Lot of refrigerators
Some super stores will have
food preparation areas, such
as a bakery, kitchen, etc.
Due to the usage requirements, a supermarket will consume significant amounts of energy. Therefore, the following
green practices are recommended for supermarkets:
1. Use energy efficient systems and equipment as per the Building Energy Code.
2. Design the lighting circuitries and air conditioning by zone to facilitate further implementation of energy
management opportunities.
3. Use cooled condenser water for refrigerators. Supermarkets should negotiate with the landlord to provide condenser
water for cooling purpose as most new retail development will use water-cooled system.
4. Provide physical separation of food preparation areas to avoid air contamination as well as an increase in the air-
conditioning load due to hot cooking processes.
