A multifunctional glazing system has the potential to reduce the heat loss through a window with control of solar heat gain and daylight. Thus it can reduce both the cooling load and heating load depending on weather, occupancy and building construction. A photovoltaic (PV) panel can be used to generate energy to change the colour of the electrochromic (EC) material. Battery storage system has been included to activate the EC behaviour using stored solar electricity. PV area and cost can thus be smaller. As a window can be placed in different sides of a building, incident solar irradiation on a PV for a particular day and time and position was calculated. Modelling of battery and PV power output was done to determine the area of PV and number of battery system for different load conditions.
