Measures to Improve Energy E ciency
In addition to building design considerations, we installed energy e cient hardware such as demand control ventilation, and high e ciency water cooled centrifugal chillers to optimise our energy use.
A destination control system has also been adopted in elevators to batch requests, thereby making fewer stops, minimising waiting time, and reducing energy consumption. Elevators are also installed with an energy regeneration drive system: as the carriage moves downward, the motor acts as a generator, transforming mechanical energy into electrical energy.
Over 80% of our electric appliances are either USEPA Energy Star rated, or Grade 1 or 2 energy e cient products under Hong Kong’s Energy E ciency Labelling scheme. We have also installed energy e cient electric lighting coupled with daylight sensors to ensure adequate lighting in indoor spaces. Occupancy sensors control lighting and reset individual room temperatures. Total energy used for lighting has been reduced from 2,318 MWh to 1,678 MWh, resulting in a 28% reduction.
The above energy e ciency measures resulted in cumulative energy savings of 22% against the baseline for the SCTC.

Use of Renewable Energy: Solar hot water heating systems
A unique feature of the SCTC are the solar thermal panels installed on its roof. These panels utilise solar energy to provide hot water for washrooms, changing rooms and the canteen kitchen.
Annual energy savings from this renewable energy system amount to 103,086 kWh.
