In a research collaboration between the National Institute of Advanced Industrial Science and Technology (AIST) in Japan and Uppsala University switchable mirrors have been evaluated from an energy perspective using energy simulations for smart windows based on gasochromic switchable mirrors. Optical properties and U values for the transparent and reflectivestates are used as input for the energy simulations. A test room has been built and is located in Nagoya; Japan. Simulations on energy use for smart windows based on switchable mirrors have been compared between three energy simulation tools. The simulations show good agreement and the simulation results also address the importance of a good control strategy for the smart windows.
