Circle House lab develops future standards for circular construction

Circle House Lab brings together the construction industry’s circular frontrunners across disciplines, in order to develop and design the future circular building standards for Danish and European construction under the auspices of the Danish Standard.

The purpose of Circle House Lab is to accelerate the transition needed to realize the potential of circular economy in Danish construction. Experience shows that the conversion from linear to circular economy is a number of challenges that need to be worked together to solve – across the construction industry.

Circle House Lab is about establishing a forum among spearhead companies and research and development organizations to develop a common understanding and solution to the most important challenges and to develop the future building standards. The name Circle House Lab indicates that its a laboratory form, where members commit to experimenting with solutions to the many challenges together – to put them into play in own businesses, education and research projects.

The knowledge gained in Circle House Lab is the basis for, in collaboration with Danish Standard, to develop European standards, which construction actors can use to explain their 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

BUILDING PASS

Gathers all relevant building information in a sole place and get an up-to-date screenshot of the building across its lifetime, with information about comfort levels (air quality, better daylight entry, etc.) and the overview of circular materials and systems used in the project.

WASTE MANAGEMENT AND TAKE BACK ARRANGEMENTS

Circular construction is gentle on the environment as resource use is smaller and the materials cleaner than usual construction, and socially sustainable as the building stock can be adapted to demographic fluctuations.

Design for disassembly

Circular construction is a new definition of sustainable construction. Smaller CO2 prints are supplemented by minor imprints for all resources that are achieved by sharing, extending and reusing raw materials which are clean materials, as it does not make sense to recycle hazardous substances. Indoor climate and health are essential results.

SELECTIVE DRIVE

Switching from linear to circular construction involves entirely new forms of collaboration, work procedures and processes. Circular building elements will be examine through the prism of their utility, affordance and reusability.

UNDEFINED LAB

The theme of the laboratory will be selected during the laboratory days.

Circle House Lab Elements

Laboratory days

To find solutions to the challenges identified in today’s theme. Pre-collected data from the participant circle, barriers, best practices and analyzes, so the work on the laboratory day itself is based on market relevant knowledge. Each laboratory day discusses the issues that are crucial for developing indicators and standards in cooperation with Danish Standard. Held at BLOXHUB and with participating companies.

Green papers

Communicates key issues and solutions that have been discussed and tested on each laboratory day. Each Green Paper is distributed to companies, researchers and students through industry organizations, industry media, the participating educational institutions and via BLOXHUB, so that knowledge from the laboratory days is spread to the entire industry.

Circle house summit

Brings together the strongest national and international actors in circular conversion in the construction of BLOXHUB. Circle House Summit is an international event where Danish companies can cement their position as front runners in relation to sustainable construction. Insights, recommendations and standards are communicated via industry organizations and a press effort in Danish and international media.

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 started up in 2017 and develops with Lejerbo as the builder the world’s first general residential building constructed according to circular principles. The goal of Circle House is a scalable circular lighthouse building that is offered and built on market conditions and is expected to be completed in 2021.

Circle House Lab operates 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).
