文章以全寿命周期的思想,通过对建筑布局、户型方案、围护结构体系和材料、制冷采暖节能等因素分析,采用现值成本法比较了建筑节能技术与传统建筑技术的成本经济效益差别,指出建筑节能在经济上是合理的、技术上是先进的、环境和社会效益是良好的、正面的。加快建筑节能的发展步伐,是推进建筑业的可持续性发展,建设节约型社会的一项重要措施。
Through the analysis of factors such as building layout, floor plan, enclosure system and materials, energy saving and other aspects of refrigeration and heating, the present paper compares the cost-benefit difference between building energy-saving technology and traditional building technology by the present-value cost method, Pointed out that building energy efficiency is economically reasonable, technologically advanced, environmental and social benefits are good, positive. Speeding up the pace of building energy conservation is an important measure to promote the sustainable development of the construction industry and build a conservation-oriented society.
