The paper describes a fuzzy decisionmalung approach to controlling thermal comfort in the occupied zones of an airconditioned building. The control objective is defined in terms of fuzzy goals and fuzzy cost functions and a fuzzy decision-maker is used to find the most appropriate control action. Simulation results are presented that demonstrate the performance of the comfort control scheme when it is used in different types of buildings. The results show that computing resources need not be wasted on calculating precise values for the control signal, when the control objective is poorly defined.
