The course will provide students with an overall view of energy use patterns in buildings, particularly large air-conditioned systems in large buildings, taking into account of environmental and economic factors. It will enable students to understand the processes of energy audit and survey, including the use of appropriate instrumentation, in order to identify opportunities for energy conservation and demand limitation in existing buildings and in new designs. Also, it will enable students to integrate and to apply their knowledge of efficient operation of building services systems, to upgrade thermal performance of existing buildings and improve designs for new buildings.
