Green Opportunities for Existing Malls - China
CapitaMall Wangjing in Beijing and Rock Square in Guangzhou underwent AEIs and achieved the US Green Building Council LEED Gold certification in September 2022.
Rock Square achieved estimated water savings of 55%1 from the installation of high-efficiency water fixtures as part of its AEI. In addition, a roof garden on the mall boasts over 70 species of vegetation, alleviating the urban heat island effect during summer while promoting public appreciation of biodiversity
CapitaMall Wangjing’s building automation (BA) system automatically controls various equipment such as AHUs and lighting fixtures, which optimises operational and energy efficiency. The heat recovery system of its fresh air unit modulates air temperature to reduce energy consumption, with a heat recovery rate of 60% in typical conditions. Along with new LED (light-emitting diode) lighting fixtures installed throughout the building, these features are estimated to reduce 250,000 kWh/year of energy consumption. Water-efficient fixtures, such as motion-activated faucets, low-flow faucets, and dual flush closets were also installed.
