Green Initiatives
Energy Saving
Energy Efficient Lighting
The traditional lighting is being replaced by LED and dimmable LED Lighting is now widely used in our Tai Po campus and study centres including offices, lecture theatres, classrooms, meeting rooms, library, student hostels.
LED flood lights were also installed for tennis courses, basketball field and swimming pools for improving energy efficiency as well as lighting level.
Motion and Daylight Sensor Control
Motion and daylight sensors are installed in various locations of our campus with motion and daylight sensing features and help to save energy when the areas are unoccupied or natural light is sufficient. If no motion is detected within a specified period, the lights would be turned off until motion is sensed again.
Smartcard Control
Users are required to use their staff/student cards to access the reserved facilities and activate the lighting, air conditioning and AV equipment. It ensures that energy and facilities are enabled only when the room is in use.
Water-Cooled Chiller Plant
Replacing air-cooled chillers by water-cooled system results in more than 20% energy saving.
Variable Frequency Drives for Fans and Pumps
Variable frequency drives are installed for the AHU/PAUs and chilled water pumps to adjust speed based on cooling demand for energy savings.
High Efficiency Air Conditioning System
Replacing old air conditioning system with high energy efficiency models such as high efficiency fan coil units, EC plug fans, inverter window type and split a/c units with “Grade 1” energy label etc.
Improve Insulation for Chilled Water Pipes
Replacement of chilled water pipe insulation with lower thermal conductivity and higher thickness to reduce energy loss of chilled water system.
High Efficient Lift Systems
The lift systems on Tai Po Campus are being replaced by phases with high efficient model with power regenerative features that can regenerate power during the deceleration of the lifts.
Optimization of Chiller Plant and Building Services Systems
The operation of chiller plant and some building services systems are optimized by Building Management System (BMS) as possible to reduce energy consumption.
