【 摘 要 】

The severe cold regions of China with characteristics of winter long, cold and snowy, summer short-lived, the heating period lasts for half a year. The heating energy consumption accounts for more than eighty percent of total energy consumption of rural residence. Because the rural houses are single-storey detached house, the heat of solar radiation has greater impact on energy consumption than urban buildings. Firstly, the temperature sensors were used to test the indoor thermal environment of different orientation rooms to clarify the effect of building orientation. Secondly, taking building orientation as main variable (set up twenty-four values, every 15°), building envelope's thermal performance as auxiliary variables (set four groups), the simulation software DesignBuilder was adopted to analyse the influence rule of building orientation on heating energy consumption under different conditions. It concluded that with the enhance of building envelope's thermal performance, the impact of building orientation on heating energy consumption and indoor temperature gradually increase, thus focus on the building orientation become more meaningful.
