Resumen de How green building rating systems are approaching circularity?

Design for deconstruction of buildings is a key-aspect for closing of the loop of materials involved in their life-cycle and contributing to circularity in the construction sector. Construction and demolition waste (CDW) accounts for more than one third of all waste generated in the European Union, so the design and installation of building systems with a focus on strategies such as minimization of material use, prefabrication and modularity, standardization of connections, ease of assembly and disassembly for replacement, reuse and/or repair of elements, as well as design for adaptability of the building to a use change, has a great potential in the reduction of CDW. On the other hand, in the built environment context there are tools specifically developed to assess the sustainability of buildings, so called Green Building Rating Systems (GBRS), such as LEED, Verde, BREEAM or Level(s), that propose indicators related to aspects such as technical, energy, comfort, water, social, economic, etc. The present work is aimed at understanding how the indicators included in the European GBRS are approaching design for deconstruction with focus on the multi-residential building sector, through the comparison with ISO 20887 standard and the Six S’s framework.
