| Abstract |
This article presents a prospective life cycle assessment of the novel building system incorporating an improved foam glass with high recycled content, considering alternative shells (clay and concrete bricks) and construction site locations. The improved foam glass (lambda = 0.037 W/m K; rho = 100 kg/m3) outperforms the commercial foam glass in most environmental impact categories. A fully electric production process is only beneficial with a high share of renewable energy sources in the electricity mix. The use of the improved foam glass can lead to a reduc-tion of climate change impacts by 64 % and resource use -fossil by 66 % in the European foam glass market. The novel building system can have good environmental performance even when assuming long-distance distribu-tion. This article advances in proposing future scenario analyses by identifying life cycle hotspots (e.g. energy in-tensity, cullet availability), including changes in production, suppliers and market demand. A prospective life cycle assessment allows to anticipate critical issues and provide recommendations for improvement.(c) 2023 The Authors.
