Energy

We pay attention to the consumption of electricity at HKUST because it is an indicator of how we are doing with regards to air pollution and greenhouse gas emissions. In the 2014-15 academic year, electricity consumption at HKUST reached 93 million kWh, which was an increase of 3.7% over 2013-14 academic year. The large electricity consumption came from several sources. In the hot and humid conditions of Hong Kong, air-conditioning within the campus has the largest impact on the consumption of electricity, especially within the academic building.

However, it is important to point out that during the colder months when the air conditioning is at its lowest levels, the electricity consumption still significant. The original academic buildings (including the main academic building plus the Coastal Marine Laboratory, the Wind/Wave Tunnel Facility, and the district cooling plant) are the major drivers of energy consumption, representing 72% out of the total. The other electricity consumption comes from student housing, staff housing, food services and common areas.

HKUST consumed about 440,00 units (roughly equal to 44 million kWh), of towngas, which is a non-renewable source of energy. Unlike electricity, the main academic building consumes less towngas than the on-campus staff quarters and canteens. One of the reasons is that the main academic building does not provide any space heating in winter.

Lastly, a very small portion of energy comes from the fuels for standby generators and transportation vehicles like cars and trucks.
