Defining strategies to adopt Level(s) for bringing buildings into the circular economy. A case study of Spain

摘要: Abstract Level(s) is a common European Union framework of core sustainability indicators for measuring the performance buildings along their life cycle, enabling emissions reductions and circular resource flows. A fundamental tool development policies to boost market sustainable, resilient climate change adapted buildings. The objective this study contribute existing body knowledge in field sustainable building research, through definition strategies adopt bringing into Circular Economy. For reason, triple SWOT-Analytical Hierarchy Process (AHP)-TOWS analysis was applied. strengths, weaknesses, opportunities threats (SWOT) have been identified relation availability resources, product quality, internal structure, consumer perception, among others. results obtained are conclusive terms experts’ positive assessment tool; highlighting factors such as its response need adapt change, standard reference language, use multiple situations. However, several barriers also identified, which may affect development, including complexity use, lack self-sufficiency, dependence criteria used each evaluation. Finally, key be carried out implementation Levels established.
