Conducting energy-efficient designs on building window can be a solution to relieving the pressure caused by growing building energy consumption. In this paper, a series of simulation studies were carried out to evaluate the performance of several popular energy-efficient window designs in...

The thermal performance of building envelopes is the determinant factor of building energy consumption, and especially envelope retrofitting is an effective way of reducing energy consumptions in existing building. For different climates, there may exist different optimal retrofitting schemes....
