The main objective of this research project on sustainability assessment is to identify the opportunities that digital fabrication can provide for sustainable construction. These opportunities are identified by assessing different construction projects employing digital fabrication methods. Some of the assessed projects are at the scale of the lab prototypes while others are projects at the building scale. From all these case studies we identified general trends or fundamental processes involved. We use the Life-cycle Assessment (LCA) method (ISO 2006) in order to evaluate the environmental impact. In most projects, the focus is on the production phase, including data from the energy and resources demand to produce the materials and robotic infrastructure, energy demand during on-site construction and waste produced during production (EN 15978 modules: A1–A3, A5). The LCA method is applied to compare the difference in environmental impacts between digital fabrication and conventional construction and to understand for which type of projects digital fabrication brings environmental benefits. The social aspect is briefly questioned through a potential understanding of what could be the organisation structure of a construction project with the use of digital fabrication. The collaborative work in this project consists of studying construction projects developed within the NCCR Digital Fabrication for research development. The interdisciplinary character of the projects and the development of demonstrators (e.g. dfab house) facilitates the understanding of digital fabrication processes to perform the analysis of environmental and social aspects.
