Green Facilities

Classrooms at All Floors

Motion Sensors: If they detect no one inside the rooms, the air conditioners and lights will be turned off automatically
Carbon Dioxide Sensors: The fresh air exchange and pre-coolers will be turned on only when the concentration of carbon dioxide exceeds the standard
T5 fluorescent tubes: help conserve energy
Auto-dimmers: If sunlight is strong, the lights by the windows will be dimmed automatically
Solar PV Panels outside windows: Turn sunlight into electrical energy and minimize heat radiation from getting into the rooms, hence lowering energy used for cooling

Double glazed windows: reduce noise and minimize heat radiation
Solar PV Panels outside windows on 6/F: Turn sunlight into electrical energy and minimize heat radiation from getting into the rooms, hence lowering energy used for cooling
Shading device: Reduce light from getting into the rooms, hence lowering energy used for cooling

Solar tracking Photovoltic (PV) panels
PV panels fixed at 22 degrees to the horizon: to enhance efficiency
PV panels over outdoor cooling units: convert solar energy to electrical energy and at the same time cover the cooling units to enhance efficiency of cooling
PV panels with water tubes: convert solar energy to electrical energy and at the same time heat up water for bathing
Water chiller plants: high efficiency cooling
Vertical wind turbine: converts wind energy to electrical energy. Optimized for urban environment
Sun tubes: lead sunlight to the Physics Laboratory by fibre-glass
Roof top garden: lowers temperature and removes carbon dioxide
Solar powered water sprinklers
Automatic weather station: beams real time weather data to classrooms to control use of air conditioning

Sunlight collecting glass canopy: allows sunlight to reach the covered playground
