建筑施工初始能耗分析及节能施工技术研究

Analysis of Initial Energy Consumption and Application of Energy-saving Construction Technology

遴选出建筑材料中内含能耗和运输能耗,采用施工现场调研和《建筑工程计价定额》相结合的方式,计算出建筑施工过程中的主要施工能耗,并将其应用于四种不同结构类型中,计算不同结构施工建筑主要建材的内含能耗、施工能耗。结果表明:砖混结构施工的初始能耗为3.89 GJ/m^2,剪力墙结构住宅能耗为5.30 GJ/m^2,框架办公楼能耗为6.98 GJ/m^2,钢结构住宅能耗为7.35 GJ/m^2,四种结构建材的内含能耗占总能耗的89 %左右。

It paper selects the energy consumption in building materials as the object,which uses the method of the construction site investigation and the construction project price quota to calculate the main energy consumption in construction process.The results show that the initial energy consumption of the masonry construction is3.89GJ/m^2,the energy consumption of the shear wall structure is 5.30GJ/m^2,and The energy consumption of the frame office building is 6.98GJ/m^2,and that of the steel structure residential building is 7.35GJ/m^2.The energy consumption in the four structural building materials accounts for about 89% the total energy consumption.
