Abstract This research analyses 44 interior partition walls (IPW) in the context of Spanish residential sector and establish the systems’ environmental profile through the application of the life cycle assessment technique. The analysis is performed within the stages of production to construction (“from cradle to handover” approach), using Ecoinvent as background database and ReCiPe as the impact assessment methodology. The analysis combines the technical requirements with the environmental data to establish the profile of the different multi-layer construction systems, with the objective of supporting the selection of the optimal elements from the design phase and promoting the development of regulations to include considerations of the embodied environmental impact in the constructive systems. The results show that the product stage has the greatest contribution to the environmental impact (78% average), followed by transport (21% average) and construction with
