减少灯具和光源产品的浪费已成为实践和研究的核心优先事项。这与灯具经常被填埋和稀有稀土元素回收不足有关。本文探讨了如何使用现代信息系统，如建筑信息建模（BIM），结合数据库，有助于提高光源和灯具的回收率。虽然有大量关于BIM和生命周期评估（LCA）的研究，但很少有研究探索BIM、LCA和照明的接口。基于文献回顾和主题专家访谈，本文有助于早期了解如何在项目的整个生命周期内系统地存储和传输有关灯具的相关环境数据。调查结果表明，最新一代BIM分类结构允许制造商和材料供应商为施工设计团队提供其产品数据。 通过以结构化数字方式提供这些数据，可以在建筑项目的整个生命周期内进行知情的环境决策，帮助回收率和材料回收。

Reducing waste from luminaire and light source products has become a core priority for practice and research. This has to do with luminaires frequently ending up in landfills and that scarce rare earth elements are seldomly recovered. This paper explores how the use of modern information systems, like Building Information Modelling (BIM), in conjunction with databases, can contribute to increasing the recycling rates of light sources and luminaires. Although there is a wealth of studies on BIM and life-cycle assessments (LCA), there is a scarcity of studies exploring the interface of BIM, LCA and lighting. Based on a review of the literature and interviews with subject matter experts, this paper contributes an early understanding how relevant environmental data about luminaires can be systematically stored and transmitted throughout the life cycle of a project. Findings indicate that the latest generation of BIM classification structures allows for manufacturers and material suppliers to make their product data readily available for construction design teams. Making this data available in a structured digital way, allows for informed environmental decision-making throughout the life cycle of a building project aiding recycling rates and material recovery.
