Abstract: An optimized heating and cooling system including a thermal mass, thermal energy transport conduits to deliver thermal energy to the thermal mass including one or more phase change materials (PCMs), at least one heat exchanger to exchange the thermal energy from a energy input into heat transfer fluid that is pumped through the thermal mass. The system also includes a controller in electronic communication with a temperature sensor, a throttle and a pump. A desired building temperature profile, a daily temperature forecast, the electricity rates, the thermal characteristics of the PCMs are entered into or obtained by the controller and the controller uses that information to optimize the energy use to avoid using the heating and cooling system during peak electricity demand time, or uses the rate structure to determine the operation sequence that results in the most efficient use of energy or least cost.
