exterior window shades

In this paper, three typical cities (Shanghai, Changsha and Chongqing) in the hot summer and cold winter climate zone of China was selected to study and the energy consumption of a model building in these three locations was simulated by eQuest software. After comparing the result, the differences among them were shown in this paper. From the viewpoint of building energy consumption, solar radiation may be a positive factor in winter but negative in summer.

In this paper, the potential of energy saving in residential building in Changsha area was studied with dynamic simulation approaches. As we know that cooling and heating are both required more or less in this climate zone considering the climate condition and solar radiation may be advantaged for winter but disadvantaged for summer. This simulation was made to analyze the effect on the air conditioning energy consumption from four aspects: the material of the exterior wall thermal insulation, the window glass type, exterior window shades, and the indoor lighting control.
