Green Opportunities from Retrofitting Existing Buildings - Singapore-Hangzhou Science & Technology Park (SHSTP), Hangzhou

SHSTP (Phase I), an integrated business park comprising three office buildings (Block 1, 2 and 3), is located close to Hangzhou Metro Line 1 and Line 8 and adjacent to Zhejiang’s largest university town. These three buildings obtained the US Green Building Council LEED O+M (Operations and Maintenance) Gold certification.

• Designed to achieve a 60.5% reduction in energy consumption with green features such as its higher performance variable refrigerant flow (VRF) units, a ductless, large-scale system for Heat, Ventilation and Air Conditioning (HVAC) performing at a high capacity, 100% LED lights, sub-metering of key equipment to optimise performance and vertical fins on the facade to minimise solar heat gain and glare. Its building management system (BMS) is also able to monitor the status of chillers, circulation pumps, air handling units (AHUs), fans, and submersible pumps.

• Installation of high-efficiency flush fixtures and smart water sensor taps will help the business park achieve a 37.1% reduction in water consumption (based on design).
