Load control options interest is growing because it can represent a response to future network investments and to congestion problems. In this frame, the present paper gives a methodology to quantify the value of load control for heat pumps (room air conditioners), in small tertiary and residential buildings, considering the occupant's comfort and the electrical grid needs for load shift. This methodology was applied to a small office building where simulations were made using TRNSYS software. It was found that a significant demand relief can be achieved by load control. However each control is followed by a recovery effect, which causes high peak consumption. In terms of comfort, this study shows that during the summer season some control strategies can be applied without affecting the occupant's comfort. Nevertheless during a heat wave comfort conditions are not achieved.
