Study on Building Envelope Optimization Parameters and Energy-saving Rate of Rural Residential Buildings in Severe Cold and Cold Zones

本文建立了严寒和寒冷地区典型农宅模型,利用TRNSYS软件计算得到了基础耗热量指标,并使用最优化算法(PSO算法)结合全寿命周期成本理论,得到了该地区农宅全寿命周期成本最小情况下的围护结构传热系数限值以及节能率,为严寒和寒冷地区农宅围护结构节能和农村建筑经济效益最优化提供了依据。

In this paper, a model for typical rural residential building in severe cold and cold zones was developed. And then,the basic heat loss index was calculated using the software of TRNSYS. Furthermore,based on the PSO algorithm and life cycle cost theory, the limited value of heat transfer coefficient and energy-saving rate of building envelope with the minimum whole life cycle cost were obtained. Therefore, the references for energy efficiency and economic benefit optimization for rural residential buildings in severe cold and cold zones were provided.
