Energy Efficiency and Conservation for Building
Design

Energy efficiency and conservation awareness form a continuous issue
which is closely attended to by the department in the design of all
projects. Overall Thermal Transfer Value (OTTV) calculations are carried
out to limit the building solar heat gain and comply with the Building
(Energy Efficiency) Regulation. Energy-efficient technologies and design
techniques are adopted in the building services installation design.
Examples of recent particular projects include the Hospital Authority
Building, Castle Peak Hospital, Public Records Office Building in Kwun
Tong, Cheung Sha Wan Government Office Building, New Naval Base,
Queen Elizabeth Hospital Operating Theatre Block, and Central Kowloon
Rehabilitation Centre. Clean energy is adopted such as photovoltaic
electricity supply in Kowloon Walled City Garden and Tai Mo Shan Radar
Station, and solar heating in Tsuen Wan Area 7 Swimming Pool and
Sheung Shui Slaughterhouse. Adequate monitoring and measuring
equipment is provided to monitor and audit building energy consumption.
