ABSTRACT

Buildings are considered major drivers of resource use and climate change. This has initiated the development of design tools that could better reflect the environmental performance of buildings. This article describes the extension of building information modelling (BIM) through the development of the sustainable resource application (SURAP) that can be used to determine the material, water, and climate footprints of buildings at the design stage. The Python application programming interface (API) of openLCA software was used with the GaBi construction materials database for the preparation of footprint data. Footprints of construction materials were determined through life cycle assessments (LCA) on a cradle-to-gate basis, and the application was developed as a new tab in the Autodesk Revit software. The Revit API was used for data exchange between the Revit core system and the developed plug-in. The application prototype was tested for the design of a multifamily building. The results show that the developed tool can support building designers in quantifying and visualizing cradle-to-gate material, water, and the climate footprints of buildings within the BIM environment. The promotion of sustainability in the building industry and its current limitations are discussed.

摘要

建筑物被认为是资源利用和气候变化的主要驱动因素。这启动了设计工具的开发，以更好地反映建筑物的环境性能。本文介绍了通过开发可持续资源应用程序 (SURAP) 来扩展建筑信息模型 (BIM)，该应用程序可用于在设计阶段确定建筑物的材料、水和气候足迹。openLCA 软件的 Python 应用程序编程接口 (API) 与 GaBi 建筑材料数据库一起用于准备足迹数据。建筑材料的足迹是通过生命周期评估 (LCA) 从摇篮到大门的基础上确定的，并且该应用程序被开发为 Autodesk Revit 软件中的一个新选项卡。Revit API 用于 Revit 核心系统和开发的插件之间的数据交换。该应用程序原型已针对多户型建筑的设计进行了测试。结果表明，开发的工具可以支持建筑设计师量化和可视化从摇篮到大门的材料、水和 BIM 环境中建筑物的气候足迹。讨论了建筑行业的可持续性发展及其当前的局限性。
