Air-conditioning has long driven up electricity bills, but a college of the Chinese University of Hong Kong has found a more sustainable way to stay cool.
Its newly introduced mixed air-conditioning system is able to cut energy consumption by up to 67 percent at springtime and around 110,000 dollars in electricity bills annually at the college.
The dining hall of Lee Woo Sing College at the Chinese University combines traditional air-conditioning with these fresh air units that treat incoming air -- able to cut humidity to around 70 percent while lowering the overall room temperature by two degrees Celsius.
The result?
A comfy indoor environment that feels just like conventional air-conditioning, with the amount of annual energy use cut by 30 percent on average compared with pre-pandemic levels. At a more humid season in April, the amount of energy use is slashed by 67 percent. The hybrid setup even allows air-conditioning to be switched off during off-peak hours without sacrificing comfort.
Prof. YAM YEUNG, Master of Lee Woo Sing College, CUHK: We have to look at the environment. We have to look at the structure, the location, where the sun is, all the factors involved. Once the custom-made solution is made available, the outcome would be just as satisfying as what we have achieved.
The college also hopes to expand the application of the energy-saving technology at this dining hall to other facilities at CUHK, as well as other tertiary institutions.
