An energy-efficient climate control system is designed for an enclosed indoor space which has been divided into a plurality of zones in which the heat losses and gains are similar. The system has means for heating and cooling water (106, 112, 124), means for supplying fresh air (128), and a control system (120, 120A, 120B, 50). Each zone is provided with a buffer vessel (122) connected to the water heating means. Each zone is equipped with a plurality of active air terminal devices (4), each having a single pipe element through which water from the buffer vessel is circulated. By controlling the temperature of water within the buffer vessel, the air temperature within each zone can be controlled in an energy efficient manner with temperature differentials between the target temperature within the zone and the water temperature of less than 15°C.
