农村住宅节能技术集成方案评价与选择研究——以天津蓟县上仓村宅外围护结构为例

The Assessemen and Selection of the Integrated Project of Energy-saving Technology in Rural Housing ——A case study of Shangcang town's exterior protected construction in Jixian,Tianjing

我国农村地区受技术条件以及经济条件落后等客观因素的制约,建筑节能技术在村镇住宅建设中应用较少。为推动节能技术在村镇住宅建设中的应用,本文以寒冷地区村镇住宅的外围护结构为例,研究分析节能技术集成方案的选择方法。首先通过分析北方寒冷地区的气候特征,选择外围护结构中适用的节能技术,然后对蓟县上仓地区的村镇住宅进行模拟,计算各种节能集成方案的建造成本和全生命周期成本,最终找出建造成本与全生命周期成本双重目标下的帕累托最优解。

Owing to the technical constraint and economic backwardness in the rural area of Ghina, there is little application of energy-saving technology in the rural construction. Based on the case study of the rural housing＇s exterior protected construction in the cold region, the paper puts forward the approaches to select the integrated projects of energy-saving technology to promote its application in new rural housing. Firstly, the paper analyzes the climate features of the cold region in Northern China and then the option of the energy-saving technology proper for exterior protected construction. Accordingly, the paper makes the calculation of the construction cost of various integrated projects of energy-saving technology and the whole life cycle cost based on the simulation of Shangcang town＇s rural buildings in Jixian, Tianjin, thus coming up with the Pareto optimal solution under the objec- tives of both construction cost and whole life cycle cost.
