Council Shopping Centre Design rating system

Case Study-4



•Low-flow water fixtures, and rain sensors

•Sealed external shop front displays to minimize western solar

heat load;

•High performance skylight with a “thermally broken frame” and

high performance insulated glazing;

•External shading to mall entries and an insulated facade through

double glazing and insulated precast panels.

•Naturally lit mall spaces hence reduce power consumption of

artificial lighting.

•Carbon Dioxide sensors to increase the outside air quantities

Case Study-4


•Low energy artificial lighting system with:

• LED lighting throughout mall

• Daylight and occupancy sensed lighting control

•A highly efficient heating and cooling system with:

• Hot layer removal and night purging systems.

• VAV handling plant

Case Study-4

•Overall, 61 per cent reduction in greenhouse gas emissions

compared to a typical retail development, equating to 3200

tonnes CO2/year.

•63 per cent reduction in potable water resulting in 13 million

liters of water saved every year compared to a typical retail

development

•Improved indoor environment quality through naturally lit mall

space.
