Building Energy Consumption Analysis And Forecast Of The Cold Area

The dissertation takes an ordinary residential building in cold area as the research object, carries on energy consumption analysis to the residential building by static manual algorithm and software dynamic simulation algorithm respectively, compares and obtains each good and bad points of the two algorithms. Then uses building energy consumption simulation software DeST-h to simulate and analyze the different influence factors of the building energy consumption, the influence factors includes different outer wall, outer window and roof structure, south window-wall ratio, north window-wall ratio as well as air exchange frequency. On the simulation and analysis foundation,the dissertation uses the orthogonal testing method to select the primary factor combinations which influence the building energy consumption, simulates 16 group of different factor combinations'building energy consumption indexes, and regresses linear equation between the building energy consumption indexes with each primary factors, this equation is available in forecasting the same type buildings'energy consumption index, and providing guidance for the building energy conservation design and transformation.
