In: CEES 2023 - 2nd International Conference on Construction, Energy, Environment & Sustainability, Funchal, Portugal, 27-30 June, 2023http://hdl.handle.net/10400.9/4226ABSTRACT: LIFE ReNatural NZEB project and is part of action B3 of the project "Demonstration experiences of NZEB with low carbon footprint". The article intends to present the results obtained in the development of the model, for which two surveys were sent to several construction companies and material supplying companies. These surveys aimed at knowing the market's ability to comply with the sustainability criteria for low carbon footprint residential buildings. The model was defined based on the analysis of national and international good practices that were collected, the EU GPP criteria and the manual "Green Public Procurement Criteria under ENCPE 2020 for Design, Construction and Management of Office Buildings". The model is divided into five parts: selection of the design team and contractors; detailed design and performance requirements; dismantling, demolition, and site preparation works; construction of the building or major renovation works; and finalization and handover. Overall, it was found that companies in the construction sector can meet most of the selection criteria for the design team and contractors and for some of the technical specifications. It was also found that material suppliers can meet the various sustainability criteria for materials.engBuildingsZero Energy BuildingsNZEBLow carbon energySustainabilityconference object
