They have designed a collection system which utilizes not only body heat, but the heat given off by such objects as light bulbs(灯泡) and refrigerators as well. The system works so well that no conventional(常规的) fuel is needed to make the campus"s six buildings comfortable.Some parts of most modern buildings-theaters and offices as well as classrooms are more than amply heated by people and lights and sometimes must be air-conditioned even in winter.
