Circular Construction Process: Method for Developing a Selective, Low CO2eq Disassembly and Demolition Plan

With the increasing focus on construction sector (e.g., following European Green Deal initiative) with aim to reduce emissions by 55% 2030 (compared 1990 levels), as well achieve full decarbonisation 2050, built environment remains a strategic domain for R&I (Research and Innovation) agenda. Indeed, building is main contributor greenhouse gas (39% of global 2018), highlighting need start process this sector. The overall reduction in environmental impact materials achieved establishing sustainable continuity between end-of-life phase production individual components. In particular, reference (BS EN 15978: 2011), Minimum Environmental Criteria foresee preparation plan disassembly selective demolition building, which allows reuse or recycling materials, components prefabricated elements used. According guidelines low-carbon design, takes into account circular economy, thesis deals methodological proposal study “dry” systems (wood steel). intends reach development such an elaboration carrying out assessment steel systems. model developed basis reading level sustainability emblematic case studies, appropriately identified, i.e., ‘quality’ architectures, ‘dry’ (steel)
