Abstract: Windows account for around 30% of the total heating and cooling loads in buildings. The development of windows with better energy performance has always been a hotspot in building technology research. However, the improvement of static properties of windows is expensive and restricted. Dynamic windows, on the other hand, show a great potential for energy saving with possibly lower cost. Movable insulation is a technology proposed a long time ago but has not been studied systematically. This paper proposes an automatic control method for movable insulation with a control accuracy of 95%. Through building energy simulation, it is found that the energy performance of movable insulation is better than triple-glazed windows in all climate zones tested and its energy savings increase with the extremity of climate. A net present value analysis is also conducted for the building designers and owners’ information.
