建筑节能方案设计与经济性分析

为提高建筑室内热舒适环境,减少建筑能源消耗,建设部于2001年颁布实施了《夏热冬冷地区居住建筑节能设计标准》(JGJ 134-2001),并提出了两种节能评价方法。对一建筑模型采用两种节能评价方法进行了节能方案设计与经济性分析评价。结果表明,若设计合理,采用性能性指标进行节能评定可明显减少建筑节能的增量成本。因此,建议建筑节能方案的设计应尽可能采用性能性指标评价法。

OVERALL DESIGN AND ECONOMICAL ANALYSIS ON ENERGY EFFICIENT BUILDING

In order to make the indoor thermal environment Design Standard for Energy Efficiency of Residential Buildings better and reduce the energy consumption of buildings, the in Hot Summer and Cold Winter Zone has been published by Ministry of Construction of China in 2001 and two methods to evaluate whether the buildings is the energy efficient one or not, have also been proposed. A typical building model is adopted to make the energy efficiency design by using the two evaluation methods above and the economical analysis are also studied in this paper. The results show that using the performance index evaluation method can make the design on the economical and energy efficiency better.
