Building planning is an important factor affecting building energy consumption.Through site planning and design,building energy consumption can be effectively reduced.This paper adopts the simulation calculation method of multi-factor coupled outdoor wind environment,light environment and total building energy consumption to calculate and analyze the influence of forward spacing,lateral spacing,orientation,building density and layout form on building energy consumption.Finally,the method of orthogonal design and difference analysis has the greatest impact on energy consumption,F value is 1,building density has the least impact on energy consumption,and F value is 0.005.By calculating the average value of the corresponding index of each factor level,the nearly optimal building layout can be found,that is,the forward spacing is 40 m,the lateral spacing is 18 m,the orientation is due south,the building density is 22.5%,and the building layout is the determinant.Compared with other layout forms,the maximum energy saving is 10%.The results of this paper provide a reference for the planning and design methods and key data indicators of multi-layer residential areas in cold areas.
