基于全寿命周期的产业化全装修住宅成本效益分析

The Cost and Efficiency Analysis of Industrialized Residence Whole-decorated Based on Life Cycle Theory

产业化全装修住宅是绿色建筑的主要发展趋势。基于全寿命周期理论,结合实际工程,采用德尔菲法、层次分析法和净现值法对产业化全装修和传统全装修的全寿命周期成本效益进行计算分析。计算结果显示,昂贵的预制成本是影响产业化全装修住宅全寿命周期成本的关键因素。研究表明,因产业化技术不够成熟和产业链不够完整,决策和建安装饰成本偏高,导致产业化全装修住宅的全寿命周期成本高于传统全装修;由于能源消耗较低,预制构配件维修方便,产业化建筑拆除技术先进、回收利用率高,使得产业化全装修住宅全寿命周期运营成本和拆除回收成本较低。因技术效果良好,环境效益和社会效益可观,随着相关技术的不断成熟,全寿命周期成本将得以降低,产业化全装修住宅将成为我国住宅产业的重要形式之一。

The industrialized and fully decorated house is the main trend of the development of the green building. Based on the life cycle theory, combined with the actual project, using the Delphi method, the AHP method and net present value method, the life cycle cost and benefit of the industrialized and the traditional decoration were calculated and analyzed. The calculation results show that the high cost is the key factor to affect the life cycle cost of the industrialized and fully decorated house. Research shows that because the industrialized technology is not mature and the industry chain is not complete, and the decision on decoration cost is high, the life cycle cost of the industrialized fully decorated house is higher than that of the traditional decoration; due to the low energy consumption, easy maintenance of prefabricated components, advanced demolition technology of industrial construction with high recycling rate, the life cycle operating cost and recycling cost of the industrialized and fully decorated house is lower. Because the technical effect is good, the environment benefit and the social benefit are considerable, and as the technology continues to mature, the life cycle cost will be reduced, the industrialized and fully decorated house will become one of the important forms of housing industry in China.
