A design process is developed for an OCCUPANCY RELATED VENTILATION CONTROL SYSTEM (ORVCS) in a new entertainment centre in Sha-tin, Hong Kong. The aim is to reduce the cost of space cooling. Little work appears to have been done in using ORVCS in conjunction with space cooling up to the present time. Thedesign process includes (a) the selection of a control parameter to modulate the fresh air supply rate (b) assumptions about the occupancy load profile and (c) estimation of the possible energy savings.
Each occupant in a room should be able to control his own indoor environment. Individual control can be achieved in many ways: from simple window-opening to automatically arranged personal mini-environment. Individual control is not utilized effectively today. This is partly caused by lack of proper information, and partly by the fact that builders pay more attention to construction than to use and operation. Even technically complicated systems can be easy to operate - what is needed is sufficient, but not too difficult user information.
