This report presents the data protocol needed for the sustainability assessments on product and building level. Requirements will be defined for geometrical information (3D models) such as building footprint and volume and semantic information, such as material properties. In addition, requirements for data on the use phase (e.g., user profiles, monitored energy consumption) will be included. The protocol will follow international standards and best-practices and define new standards where needed and is mainly targeted at product developers and environmental impact assessors. The key point delivered in this report is a concise protocol to conduct beyond the state of the art environmental and circular impact assessment.
