Circle House lab develops future standards for circular construction
Circular House lab gather more than 80 circular frontrunners across the building industry, with the aim to develop the future national and European circular building standards.
Circle House Lab aims to accelerate the transition to circular economy in the Danish building industry. Experience shows that the change from linear to circular economy results in a number of challenges, that need to be solved on a global scale, by collaboration across the industry.
As the name indicates, the Circle House Lab is a laboratory. Members commits to engage with experimenting solutions and think in collaboration across the industry.
The knowledge gained in Circle House Lab will be the starting point of a development of a European standard for circular processes and products. The project is supported by Realdania and MUDP and runs from spring 2019 to summer 2021.
Development of solutions and standards
In addition to serving as housing, Circle House is a scalable demonstration project that can give the construction industry new knowledge about the experience of circular building.
The transition to building circular implies, among other things, that the materials must be produced so that they can be separated. It is not just a purely technical challenge. Today, some of the elements in the building’s value chain are also missing, which are necessary for the materials to be recycled. Manufacturers will only in a few cases take back their own used products so that they can be sold again. And leasing, known from cars, is not yet developed for construction.
There is also a need to renew the traditional business models and ensure that the legislation supports recycling, whose circular construction really needs to accelerate. For example, it is currently unclear who is responsible for the quality and the material used.
The Circle House project wants to get closer to the answers to these challenges. So, the project analyzes value chains, business models, business cases and framework conditions. All results and recognitions are shared through a broad discussion of circular construction throughout the industry.

The 3 processes of the laboratory
Standards is like a common language, that able us to communicate and pass on information in a common tongue. It is with standards we ensure that the light pulp fits the lamp, that the nut fits the bolt. Standards are the key to establish a common foundation for the handling of materials reuse, and necessary to accelerate the transformation to a Circular industry.
Circle House Lab will process and develop standards within six topics; Building passport, waste management and take back arrangements, Design for disassembly and selective demolition. The two final topics will evoke from experiments and dialogs in the laboratory.
All topics will be treated through three types of activities:
Share the knowledge!
Circle House Lab aims to push all in the industry towards a circular economy. The key to make a change beyond you own ability is sharing your knowledge. We believe that knowledge sharing is one of the strongest tools to cause a change. That is why we believe in opensource. The knowledge and discovery from Circle House Lab will be updated and shared on this webpage and in a cloud folder.
For everyone to access!
FROM A LINEAR TO A CIRCULAR ECONOMY
In Denmark, the construction sector accounts for 1/3 of the total materials waste volume and globally for around 1/3 of carbon dioxide emissions. One of the reasons for this is that the economic model that prevails in the building industry today is linear. In real terms, this means that raw materials for construction are mined and excavated, building components are manufactured and subsequently used in buildings, and ultimately they end up as construction waste.
One possible solution to this immense challenge is to switch from a linear economy to a circular economy. The transition to circularity in the built environment means, for example, that products must be manufactured so that their constituent materials can be separated out. This is not only a technical challenge, but also calls for recirculation capabilities in the building industry value chain that do not as yet exist. In only a few instances do manufacturers take back their products for resale.
The Circle House project wants to get closer to the answers to these challenges. So, the project analyzes value chains, business models, business cases and framework conditions. All results and recognitions are shared through a broad discussion of circular construction throughout the industry. Realdania has supported this part of the work.
Who is behind the Circle House Lab
Circle House Lab builds on the circle of companies behind the Circle House project.
Circle House Lab is a continuation of the company developments and collaborations from the project Circle House. With Lejersbo as the developer, Circle House is designed to be the world’s first residential building constructed according to circular principles. The aim of Circle House is to create a circular example that is offered and built on market conditions. The project is expected to be completed in 2021.
Circle House Lab is run by GXN and Responsible Assets, in collaboration with Danish Standard.
Circle House Lab is anchored physically and digitally at BLOXHUB, where knowledge from projects and events can be accessed. The project is supported by: Realdania and the Danish Environmental Protection Agency’s Development and Demonstration Pool (MUDP).
