According to buiding thermal environment in hot summer and cold winter region,puts forward to the method of determining air conditioning period and dehumidifying period,and builds the basic calculation procedure of fresh air cooling consumption.

Under the three basic kinds of different conditions, namely, different climates, different fresh air supply ways, whether distinguishing interior and exterior zones, the statistical air-conditioning design cooling load and all-year cooling energy consumption indexes in high-rise office building were got by arranging spare factors resort to orthogonal table and afterward simulating by DOE-2.

Effect of area ratio of window to wall on cooling and heating energy consumption index and energy efficient rate for residential buildings;
