Environmental assessment is a critical activity for ensuring buildings are performing according to specified requirements, and efficient, seamless exchange of building information is crucial for environmental assessment. Therefore, all those involved in built environment issues should be able to access and share not only building information but also data about products, especially environmental assessment results for the products used in building projects. Of the several approaches that have been proposed to achieve efficient information exchange, semantic web technologies are amongst the most promising due to their capability to share data and enhance interoperability between the most heterogeneous systems. This study proposes an approach that can be used to make environmental data available in the early phases of the building lifecycle. It relies on Semantic Web techniques, especially Linked Data principles, while building on emerging Building Information Modelling (BIM) technology to propose an approach that facilitates information exchange to enhance the sustainability assessment of buildings. The paper ends with an illustration of how lifecycle inventory databases can be integrated, linked to BIM software and used in exchanging environmental building data.

环境评估是确保建筑物按照指定要求运行的关键活动，而高效，无缝的建筑信息交换对于环境评估至关重要。因此，涉及建筑环境问题的所有人员不仅应该能够访问和共享建筑信息，而且还可以访问和共享有关产品的数据，尤其是用于建筑项目的产品的环境评估结果。在已提出的实现有效信息交换的几种方法中，语义Web技术是最有前途的技术，因为它们具有共享数据和增强大多数异构系统之间的互操作性的能力。这项研究提出了一种可用于在建筑生命周期的早期阶段提供环境数据的方法。它依靠语义Web技术，尤其是链接数据原理，同时以新兴的建筑信息模型（BIM）技术为基础，提出一种促进信息交换以增强建筑可持续性评估的方法。本文最后说明了如何集成生命周期清单数据库，如何将其链接到BIM软件以及如何用于交换环境建筑数据。
