Madaster is an online one stop access point for information for registration of products, components and material used in construction objects. On the platform, registered data is safely stored, smartly enriched, easily shared, and managed. It generates material – or building - passport that create transparency about materials, components and products used. Enriched with data from other sources and services from third parties, this digital twin of buildings creates insight in the financial and circular valuation, toxicity, detachability and reuse potential of the applied material, components, and products. The real estate owner is the data owner and can give access to these data and insights to internal and external partners at any given moment. For real estate owners, Madaster is offered on a subscription basis, non-building owners can acquire an Enterprise licence. In our partner programme we offer different models. Students and universities can get access to the Madaster Education Environment.
