Abstract

This study aims to evaluate the extent to which building material specification affects life cycle environmental performance, using a building information modelling (BIM)-enhanced life cycle assessment (LCA) methodology. A combination of the BIM-based design and analysis tool Revit Architecture, the energy simulation tool Green Building Studio (GBS) and the LCA tool ATHENA Impact Estimator were used for the assessment. The LCA was carried out on a life case study of a 2100 m2 two-floor primary-school building, as well as a variability analysis, by varying the material specification in terms of whole building materials. The life cycle performance of the buildings was primarily evaluated in terms of its global warming potential (GWP) and health impact.The findings of the study show that irrespective of the materials used, buildings that are based on renewable energy perform better than those based on fossil fuels over their life cycle. In terms of building materials, both environmental and health preference...

材料规格的生命周期环境性能:bim增强的比较评估

本研究旨在利用建筑信息模型(BIM)增强的生命周期评估(LCA)方法，评估建筑材料规格对生命周期环境绩效的影响程度。结合基于bim的设计和分析工具Revit Architecture、能源模拟工具Green Building Studio (GBS)和LCA工具ATHENA Impact Estimator进行评估。LCA是在一个2100平方米的两层小学建筑的生活案例研究中进行的，并通过改变整个建筑材料的材料规格进行了可变性分析。建筑物的生命周期性能主要根据其全球变暖潜能值(GWP)和健康影响进行评估。研究结果表明，无论使用何种材料，基于可再生能源的建筑在其生命周期内都比基于化石燃料的建筑表现更好。在建筑材料方面，无论是环保还是健康偏好…
