Comfort air-conditioning control for building energy-saving

In buildings such as offices and department stores, the requirement is that the room air-conditioning control system has to provide a comfortable thermal feeling for the inhabitant. While energy saving may sometime conflict with comfort, it is possible to eliminate the wasteful use of energy associated its overuse without prejudice to comfort. The basic concept is that the target set values for the room temperature should be changed dynamically so as to suit the constantly changing room environment. This paper shows that the well-known comfort index PMV is useful to air-conditioning control systems aimed at both energy-saving and comfort.
