- Abstract
- Adaptive reuse, the conversion of buildings for new functions, is gaining prominence for its cost-saving and environmental benefits. However, prior research primarily focuses on preserving the building envelope, often overlooking building services such as ventilation, which affect occupant well-being, costs, and environmental performance. This study explores a novel adaptive reuse approach by reusing existing ventilation systems in a conceptual office-to-residential conversion in Malmö, Sweden. The architectural layout was designed around existing diffusers to minimise environmental impact and life cycle costs. Using Life Cycle Assessment (LCA) and Life Cycle Costing (LCC), two reuse scenarios were evaluated against a baseline with full... (More)
- Adaptive reuse, the conversion of buildings for new functions, is gaining prominence for its cost-saving and environmental benefits. However, prior research primarily focuses on preserving the building envelope, often overlooking building services such as ventilation, which affect occupant well-being, costs, and environmental performance. This study explores a novel adaptive reuse approach by reusing existing ventilation systems in a conceptual office-to-residential conversion in Malmö, Sweden. The architectural layout was designed around existing diffusers to minimise environmental impact and life cycle costs. Using Life Cycle Assessment (LCA) and Life Cycle Costing (LCC), two reuse scenarios were evaluated against a baseline with full duct replacement. The fixed-position reuse scenario, where ducts remained in place with minor changes, achieved a 99% reduction in costs and global warming potential (GWP). The full disassembly and reinstallation scenario, where ducts were removed, inspected, and reinstalled, resulted in 50% cost savings and a 98% GWP reduction. Cleaning, long-term maintenance, and reusability testing were excluded due to data limitations. Therefore, these percentage-based results reflect only partial lifecycle impacts and should be interpreted with caution. A reference LCA and LCC metrics per metre of reused duct were developed to support comparison across different projects. (Less)
