Abstract | Upgrading the window glazing can help minimize the energy consumption through a
reduction of solar heat gain in summer or indoor heat loss in winter. On the other hand,
the mutual shading caused by surrounding high-rise buildings could affect the energy
performance of the window glazing. In hot climate, mutual shading could further reduce
the solar heat gain. In cold climate, overshadowing lowers the solar heat gain in winter
resulting in greater demand for space heating. To explore the most energy-efficient
window glazing for different climates, it is imperative to integrate mutual shading with
window retrofit measures when evaluating the thermal performance of a building. This
study applies a computer-based simulation program known as DesignBuilder to assess the
building performance. The energy model is based on a typical high-rise residential
building, and four common double energy-efficient glazing alternatives were employed in
lieu of single clear glass. The results show that the optimum window retrofit solution
vary with different climatic conditions and there are different choices for upgrading
window glazing in the same building with and without the consideration of mutual
shading due to the mutual shading effect on the energy use. |
