Abstract: The objective of this project is to analyze the energy saving performance by optimizing buildings’ orientation in the representative cities, such as Beijing, Shanghai, Guangzhou, Kunming and Harbin, in China. In order to estimate the annual energy consumption of buildings in different orientations, EnergyPlus is adopted as the simulation software. And the measured subentry energy consumption is used to calibrate the building models. The result of simulation indicates two valuable conclusions regarding the buildings’ orientation. Firstly, if the building is located in the city such as Beijing, Shanghai or Harbin, south orientation would be the best choice; however, if the building is located in the city such as Guangzhou or Kunming, it is better to face north. Secondly, by appropriate use of daylighting and shading technology, the annual energy consumption of building can be dramatically reduced. Therefore, these technologies are worthy popularizing.
