For smart windows
A buildings energy demand is greatly impacted by its windows. They usually represent the most vulnerable part of the building skin for radiator heat loss and show the highest interaction with sunlight and solar heat. Therefore, depending on the number of windows in a building’s façade, they are usually responsible for 30 – 40% of total energy loss. Energy-efficient windows commonly either focus on reducing radiator heat loss via increased insulation, or on reducing cooling demand via blocking of solar heat. Since these two functionalities are conflicting with each other, current energy-efficient glazing systems are only optimized for either hot or cold climates.
To solve this issue, we develop an energy-efficient window which is optimized for intermediate climes, where heating in winter is equally important as cooling in summer.
