Shape and Direction of Energy-saving Brickwork Dwelling House in High Altitude Area;

Plan design of residential building is usually based on intuition,so there are often shortcomings in room orientation,natural lighting,ventilation and energy saving,causing some problems in its function.

This is followed by the analysis of impacts,including heat exchange values of outside wall,orientation of the building,air changes in transitional season on the indoor loads.

Analysed influences of opaque part,translucent part(glass window) in building envelope and different orientation to total energy consumption of building,got their influence rules to total energy consumption of building.
