Access to data on built environment in national, regional and local databases makes nowadays possible generating models of our urban spaces to facilitate visualization and analysis of information and synthesize it in sustainability indicators.
Life Cycle Assessment (LCA) can greatly benefit from this wealth of potentially available information. In particular, the use of LCA data in models developed in the Building Information Modelling (BIM) platform would facilitate the implementation of quantitative environmental assessment in the construction field. However, there are presently very few examples of LCA-BIM coupling, because this coupling requires a level of technical integration that has not yet been achieved. In fact, despite the clear advantages of BIM methods for urban planning and management, existing BIM software lacks interoperability with conventional LCA tools.
Another very important and timely research theme within the sustainable urban planning and management context, not currently explored in LCA, is the use of nature-based solutions (NBS). Those represent, among others, a means to activate impact mitigation measures in cities. NBS strictly belong to the sustainable management of natural resources, urban spaces and technological know-how. Their implementation in urban contexts (neighbourhood, or whole city) is recommended for different reasons, such as to enhance the well-being of individuals and communities and the provision of urban ecosystem services and biodiversity. However, the impact of NBS projects, in terms of benefits, co-benefits and costs still remains not sufficiently understood. Hence, the investigation of NBS-related impacts based on an LCA approach could facilitate the interpretation of the sustainability dimensions underpinning NBS.
This session aims at exploring the above mentioned integration issues via some case studies presentation, proofs of concept and a discussion on different experts’ visions.
