thermal energy storage

Recently, buildings with thermal energy storage system have increased because of its economic advantage. In thermal energy storage system using introduced outdoor air, building masses are used as thermal storage media and cooled by outdoor air introduced by a mechanical fan in night-time. In spring and autumn, the cooled building masses can work to reduce cooling load in day-time. In this study, the stored heat was calculated by using simple heat transfer models for various building masses, and the energy performance of this system was evaluated quantitatively by system simulation.

As part of a long-term investigation into fabric energy storage systems, EA Technology has been monitoring the headquarters of Weidmuller Interface, the first UK application of Termodeck, since the building was occupied in July 1994. Has the system lived up to expectations?
