The Chinese University of Hong Kong has long pioneered a green campus culture by spearheading innovative measures and a wide variety of education activities in support of environmental protection. In October 2007, CUHK organized another Environmental Protection Week and the theme was ”„Building a Sustainable Campus”¦. The event was officially kicked off by Mr. Edward Yau Tang-wah, Secretary for the Environment.
At the opening ceremony, Mr. Yau and Prof. Lau presented a number of environmental awards to buildings that have made outstanding achievements in energy saving. The awardees include the winners of the Energy Saving Incentive Scheme and the Energy and Water Saving Contest for Student Hostels. Mr. Yau and Prof. Lau also presented a Certificate of Commendation to 27 student hostels that are fitted with evacuated tube solar collectors. By using solar heated water for showers, these hostels are promoting the use of renewable energy. The officiating guests also visited a hostel (Adam Schall Residence) to symbolically power on its solar water heater system at its rooftop. This underlines the University”¦s commitment to sustainable development.
The solar hot water system for the student hostels was funded by the University Grants Committee. CUHK installed its first solar hot water system at the Cheung Chuk Shan Amenities Building as early as 2004, making it the first local university to use this system. The initiative was later extended to the University Sports Centre. Unlike conventional flat-plate solar heaters, the vacuum outer layer of this solar collector acts like a vacuum flask, thereby minimizing heat loss.

Its evacuated tubes maximize the collection and conduction of heat, substantially increasing efficiency. On sunny days, the system can provide hot water of up to 90 degrees Celsius.
Environmental Protection Week is aimed at raising the environmental awareness of our staff and students, and encouraging them to live an environmentally-friendly life. The event comprises exhibitions, film discussion sessions, and a Community Afforestation Scheme that will plant over 10,000 trees on Grassy Hill, Shatin to green the area and prevent wildfire.
