Study on load prediction with operation data for control of thermally activated building system

A type of a radiant system that uses the building concrete structure as energy storage, Thermally Activated Building System, is an energy efficient system, which utilizes the time-delay effect. Although the time-delay effect of the Thermally Activated Building System may be beneficial for the use of energy storage, it may also cause difficulties while controlling the system. When the system is not controlled properly, overheating and overcooling statement in the room and condensation on the surface may occur. For the proper use of the Thermally Activated Building System, the system has to provide the energy into the room as much as the amount of heating and cooling loads while keeping the setpoint temperature in the room. Since the starting operation time of the Thermally Activated Building System does not accord with the starting time of energy provided into the room,

1.  heating and cooling load should be predicted and
2. the time delay of the thermal output of theThermally Activated Building System needs to be analysed. This research is a preliminary study on the first part of the optimal operation of the Thermally Activated Building system, which presents a method to predict the heating and cooling loads with the operation data.
