A new user-friendly, personal computer program, ACCURACY, has been constructed for energy analysis, room air temperature and contamination field predictions. The program is a coupling of a cooling load program and an airflow program. It is based on the room energy balance method and uses Z-transfer functions and window energy balance equations for heat transfer t~ough enclosures. The computer program also involves the solution, in finite-domain form, of threedimensional, transient equations for the conservation of energy and contamination concentration using airflow patterns, which are precalculated from dedicated computer programs, such as PHOENICS (3D) and CHAMPION SGE (2D). The influence of room air supply system on the temperature distribution and indoor air quality and subsequently on the energy consumption can be calculated by ACCURACY. The agreement between measured and simulated results by ACCURACY is good.
