  • The Circularity Passport – A step towards a zero-waste construction industry

    The LEGOFIT project is a pioneer in the Circularity Passport, a digital tool designed to transform the construction industry towards a zero-waste future. By integrating material data, circularity strategies, and sustainability guidelines, this passport enables buildings to maintain their value throughout their lifecycle. It will provide real-time insights on material properties, recycling potential, and reuse strategies, helping architects, engineers, and policymakers make informed decisions. As part of LEGOFIT’s broader efforts to promote Positive Energy Buildings and Districts, the Circularity Passport will play a key role in reducing construction waste, lowering carbon emissions, and supporting the transition to a fully circular economy.

  • The Digital Building Logbook: Transforming building data archiving for a sustainable future
