Dynamic temperature setpoint control as a strategy for reducing costs and energy consumption in nearly zero-energy buildings

European countries start rising the standards regarding the energy performance of buildings by adopting the European Commission's directives with the purpose of driving change in the building sector and promoting a low carbon economy. The energy performance of buildings and the related costs with energy can be reduced from the design phase, by choosing high quality and energy performant materials and by implementing automation systems which adapt the behavior of buildings in relation with the energy grid and the energy market. The automation systems can follow different strategies for reducing the consumption and power demand, while keeping the indoor comfort within limits, and they can react and change the behavior of building systems according to the changes in the energy market, in the local energy production potential and in the weather forecast, which can affect the demand for energy.
