预制技术由于其提高建筑质量和生产力的潜力而受到中国政府的大力推广。然而，迫切需要评估预制技术的环境性能，以确定它是否是一种有利于可持续发展的有效方法。本研究以两个典型的住宅工程为例，对预制技术和现浇技术进行了比较。数据收集采用了多种测量方法，包括内容分析、面对面访谈和现场测量。环境影响（EI）类别选择的研究包括资源消耗，能源消耗和建筑废物排放。两个生命周期评价（LCA）为基础的模型，建筑环境性能评价系统（CEPAS）和建筑健康影响评价系统（BHIAS），被集成到测量的EL的两种建筑技术的基础上的三个损害类别，即生态系统损害，资源枯竭和健康损害。最后，社会支付意愿（WTP）被应用到整合的损害类别进行比较。结果表明，样本装配式住宅建筑（PRB）建设是更有效的能源利用，与样本传统住宅建筑（TRB）建设相比，减少了20.49%的总消耗。采用预制构件进行生态修复具有一定的优势，资源消耗减少35.82%，健康损害减少6.61%，生态系统损害减少3.47%。与传统的现浇施工技术相比，预制技术在减少对环境的破坏方面具有优势，因此更加环保。(C)2015爱思唯尔有限公司版权所有。
Prefabrication technology has been heavily promoted by the Chinese government due to its potential to improve construction quality and productivity. However, there is an urgent need to assess the environmental performance of prefabrication technology to identify whether it is an effective method that is conducive to sustainable development. This study considered two typical residential projects using the two technologies to conduct a fair comparison between prefabrication technology and cast-in-situ technology. Various measuring methods, including content analysis, face-to-face interviews and on-site measurements, were used for data collection. Environmental impact (El) categories selected for the study included resource depletion, energy consumption and construction waste discharge. Two life cycle assessment (LCA)-based models, the construction environmental performance assessment system (CEPAS) and the building health impact assessment system (BHIAS), were integrated to measure the El of the two construction technologies based on three damage categories, namely, ecosystem damage, resource depletion and health damage. Finally, social willingness to pay (WTP) was applied to integrate the damage categories for comparisons. The results indicated that the sample prefabricated residential building (PRB) construction was more efficient in energy use, with a 20.49% reduction in total consumption compared to the sample traditional residential building (TRB) construction. The use of prefabrication demonstrated a certain degree of advantages in El, including a 35.82% reduction in resource depletion, a 6.61% reduction in health damage and a 3.47% reduction in ecosystem damage. Prefabrication technology was more environmentally friendly because of its advantages in reducing damage to the environment compared with traditional cast-in-situ construction technology.
