The Atlas of Regenerative Materials is an open-source knowledge platform providing reliable and interconnected information about construction with regenerative building materials. This platform is backed with a database structured around the 5 main entities Resources, Building Materials, Construction Techniques, Professionals, and Buildings. Together they illustrate the whole value-chain. The target public goes beyond the field specific audience of students and academic or industrial experts to decision makers and the broad public. This is why the mere scientific data sheets are supplemented with anecdotal and personal tidbits in all formats: text, image, audio, video etc. An expert community of professionals provides information according to their specific know-how or knowledge. All entries are peer-review and thus shall render the Altas of Regenerative Materials the go-to resource for information regarding sustainable construction. The website is up and running since 27.6.2025 We are constantly improving and adding functionalities for user-friendliness and comprehensiveness. For the 2nd period of the project, we have focused on community management, input curation and enhancement of the platform. As we continue beyond 02/26, we will wrap up our work with SDSC on introducing semantics to the taxonomies and continue with the expansion of the Atlas- especially integrating befriended associations’ and organisations’ address books.
