The daily dissipation energy of the building has hit the air conditioner and taken the large proportion definitely with the electricity, so discuss from the air conditioner that energy conservation of building have a definitely great result. Because the building has long performance life on the other hand, its energy-conserving accumulation result is better than other industrial products far. We can even say that the design of the energy conservation of building is the country economizes most potential ring of energy policy.
Influencing the Envelope Load and consuming energy, relevant factors include the open ratio of windows, the position, the sunshade, and the heat insulation. If we can know the disposing, proper open ratio of windows, the matching good building materials, the outside sunshade, and design of position, we can grasp almost all the dissipation energy characteristic of the building, and reach the goal of the energy conservation of building.
According to the Technical Code for Energy Conservation Design of Buildings 2005 Edition, using Lin’s Method and Building Energy Evaluation Program (BEEP-II) and the mean, standard deviation, coefficient of variance of statistics to analyze the effect of the position, the material of walls, the material and the open ratio of windows, and the outside sunshade designing on the Envelope Load.
Keywords：Energy Conservation of Buildings, Windows’ open Ratio, Lin’s Method, Envelope Load, Mean, Standard Deviation, Coefficient of Variance.
