Återbruk av fönster - en handlingsplan för aktörer inom byggbranschen

Sammanfattning

The waste and carbon emissions in Sweden is comprehensively contributed by the construction industry. With focus on the growing need for raw materials, reports indicate that by 2060 the use of raw materials is expected to increase by 50%. It is evident that the production of windows can have negative environmental consequences, from extraction to its contribution to a building’s energy consumption. By centering on the circular economy framework, this study aims to promote reuse of windows, by focusing on environmental, economic and quality factors. Through literature reviews, case studies and stakeholder interviews, this study focus upon window reuse in construction projects in a feasible manner. The absence of knowledge and logistical concerns hinders the reuse of windows, despite its environmental and economic benefits. Reuse relies on inventory, digital logistics and collaboration among stakeholders as a vital key motivator. Furthermore, limited support and resources has been identified as some of the key obstacles for progress and implementation of reuse of windows. Emphasizing on the importance of responsibility allocation and considering sustainability throughout the entire construction process. Quality criteria for window reuse include energy efficiency and cultural value. Despite challenges such as economics, logistics, collaboration and the share of knowledge, it’s believed that this study can significantly transform the reuse process and steer towards a more sustainable future.
