Research, policy, tools, and field knowledge for the circular built environment — where universities, R&D centres, policymakers, innovators, and experienced practitioners share what they know with the people who can act on it.
Horizon Europe projects produce findings that never reach the contractor who needs them. EU regulations reshape procurement rules that half the market hasn’t read yet. A university in Eindhoven develops an LCA methodology for reused materials that an architect in Vienna is still trying to figure out independently. A federation publishes a best practice guide that circulates within its membership and nowhere else. A startup demonstrates a robotic deconstruction technology at a conference in Amsterdam that a developer in Warsaw will hear about three years too late.
This category exists to close that gap.
Knowledge & Research is the intelligence layer of (re)build — the place where the full spectrum of circular construction knowledge, from peer-reviewed research to field-tested practice, from EU policy to startup innovation, is shared with the professionals who can put it to work.
Who belongs here
This category is for everyone who generates, synthesises, or applies knowledge in the circular built environment:
-
Universities and research institutions — share your findings, your methodologies, your ongoing projects. Industry is here and ready to engage.
-
R&D centres and technical institutes — Buildwise, CSTC, Fraunhofer, TNO, VTT and their equivalents across Europe. Your applied research is exactly what this community needs.
-
EU-funded project consortia — Horizon Europe, Interreg, COST Actions, Life projects. If public money funded the research, the built environment professionals who need it are here.
-
Federations and confederations — national and European construction federations, material associations, professional bodies. Your policy positions, guides, and market reports belong in this conversation.
-
Policymakers and European Commission — regulation documents, consultation processes, implementation guidance, what is coming and when. Practitioners need to understand policy before it lands.
-
Journalists and analysts — articles, investigations, market reports, trend analysis. If you are covering the circular built environment, your audience is here.
-
Startups and technology innovators — new tools, platforms, and approaches that are changing how the sector operates. If you have built something that solves a real problem, share it with the people who have that problem.
-
Practitioners with field experience — the knowledge that lives in project files and hard-won experience is as valuable as any paper. If you have learned something the hard way, share it here.
What belongs here
-
Research papers, journal articles, and academic publications on circular construction, embodied carbon, material reuse, and whole-life carbon
-
EU-funded project outputs — Horizon Europe, Interreg, COST Action deliverables, Life project results
-
Policy and regulation analysis — EPBD implementation, EU Taxonomy for construction, national circular economy strategies, procurement frameworks
-
LCA and EPD methodologies — tools, databases, approaches, limitations, and ongoing debates
-
Market reports and industry surveys — material availability, pricing trends, adoption barriers, regional comparisons across Europe
-
Technical guides and best practice documents — from federations, research centres, and professional bodies
-
Tool and technology reviews — LCA software, BIM for circularity, material tracking platforms, digital building passports
-
Innovation and emerging technology — robotics for selective deconstruction, AI for material identification and carbon optimisation, sensor technologies for material tracking, digital twins for end-of-life planning
-
Startup showcases — new solutions solving real problems in the circular construction value chain
A note on the balance we are looking for
Pure academic rigour and pure field experience are both welcome here — but the posts that generate the most value are the ones that bridge both. A research paper shared with a paragraph explaining what it means for a contractor bidding a circular renovation project. A field observation connected to the methodology that explains why it happened. A policy document unpacked for the professional who needs to comply with it by next year.
Knowledge that stays theoretical stays useless. Knowledge that travels and connects is what accelerates the transition.
If you have something worth sharing — share it here.
