CHARM - Circular Housing Asset Renovation & Management

Project Summary

The building sector is responsible for more than 60% of resource use in Europe with more than 30 - 50% of material use taking place in the housing construction sector. The sector also generates about one third of all waste in the EU. It is because of these staggering statistics that increasing resource efficiency in the housing sector is of great importance for a sustainable society.

Main objective of project CHARM: optimise (re)use of material and natural resources

The main project objective of CHARM is to optimise (re)use of material and natural resources. Other objective is to demonstrate innovative approaches for housing renovation and asset management that prevent downcycling. The project also wants to secure adoption of these approaches within the housing organisation partners, as well as to accelerate the adoption of such approaches throughout the social housing industry.

Asset management approach

Currently, the trend is to improve recycling of building materials from demolition waste. This often leads to downcycling, reducing the use value of materials. For example, concrete from buildings being converted to form the foundations of roads. A circular economy promotes optimal reuse of building materials at at least an equivalent value, such as bricks reused as bricks. CHARM develops and implements an asset management approach that prevents downcycling of materials in renovation and construction of social rented dwellings by creating:

  • circular building strategies tested in demonstration exemplars
  • guidelines for a circular procurement strategy for social housing organisations
  • material exchange platforms to enable circular flows of materials and building components in the social rented sector

Project partners

The project output will be jointly generated by social housing organisations from 4 countries in the InterregNWE region (Belgium, France, the Netherlands, United Kingdom), in co-creation with supply chain partners and knowledge institutes. The social housing organisations and partners are: Zonnige Kempen, Paris Habitat, Stichting Woonbedrijf SWS.Hhvl and Accord Housing Association. Other partners of the project are: European Federation for Living (EFL), Kamp C and the University of Birmingham. Lead partner of project CHARM is TU Delft. 

Outcome

The CHARM building strategies will lead to 36% of materials being prevented from downcycling, compared to the current maximum of 10%. This is equivalent to 40.000 tonnes of annual material recovery by the project partners alone. Dissemination and uptake of the results in the social rented sector in the NWE region will be achieved through the involvement of European, as well as national, innovation exchange platforms.

Activities

Belgian/Dutch Online Training Workshop

, online training session

This online workshop session will discuss circularity. We will talk about circularity and where to start. The circular pilot project of Zonnige Kempen will be highlighted (from a circular renovated office to circular homes) and Woonbedrijf Eindhoven is going to talk about the choice to choose for 100% circular projects or use circular components in housing projects. We end the session with a workshop on getting started with circularity.

The project output will be jointly generated by social housing organisations from 4 countries in the Interreg North-West Europe (NWE) region. Interreg NWE is a European Territorial Cooperation programme with the ambition to make the North-West Europe area a key economic player and an attractive place to work and live, with high levels of innovation, sustainability and cohesion.

CHARM addresses the challenge to create a resource efficient society, focussing on social housing. The housing organisation partners of CHARM have begun to experiment with more circular approaches towards construction and renovation. Here, you will find more information on these experiments, which we call 'demonstration exemplars'.

Making the social housing sector more circular also means that we have to share the information we have and are collecting on CHARM, circularity, and interesting websites.

CHARM tutorial

This online tutorial consists of 3 episodes. It is build up upon the Interreg NWE funded project CHARM. The project has been running for five years (2019 - 2023). We developed the tutorial to facilitate adoption of the approaches developed by the CHARM partners to incorporate circularity in their housing development and renovation.

In the first part of the tutorial, we introduce the background of the project.

CHARM tutorial part 1

In the second part we dive deeper into the demonstration exemplars that have been developed by our social housing organisation partners.

CHARM tutorial part 2

In the third part we explain the basics of material exchange platforms for social housing organisations, distinguishing a physical and a digital variant. We employ the sustainable business model canvas (developed by Bocken et al. (2018) based on Osterwalder &Pigneur (2010) and Richardson (2008)) to structure the explanation of the approaches in the tutorial.

CHARMing Talks

CHARMing Talks is a initiative of Sultan Çetin-Öztürk (TU Delft). She is also the host of this webinar. Peter Hoogeweg (EFL) is co-hosting the webinar. The webinars are about 30 minutes and are handling two topics on sustainability and/or circularity in the construction sector. All webinars are being recorded and published.

 

CHARMing Talks #1 is about the virtually plastic-free houses of Accord and the Green Light District in Amsterdam of De Groene Grachten.

CHARMing Talks #2 is about how MetroPolder keeps cities more liveable through smart water management on paved surfaces. And Paris Habitat and the circularity measures in their renovation projects in Paris.

CHARMing Talks #3 is about Circular Maker City, a research project of Delft University of Technology. And Kamp C about their - award winning - Circular Procurement. 

CHARMing Talks #4 is about Energy & Circularity in housing renovation. Maarten Hommelberg of Flitshome - introduced by Ad Straub - told about their solution.

Tour 't Centrum of Kamp C in 2023 

By offering a broad view on circular construction and by constructing the first circular building itself, Kamp C wants to get this innovative and sustainable way of building off the ground in Flanders, Belgium. The pilot project around 't Centrum provides insights into the obstacles and solutions. In this way we accelerate the much-needed circular transition in the construction sector. A tour can be booked in 2023.

The seminar will take place on 21 September 2023, starting at 09h30 until 16h00. Venue: Delft Bouwkunde in Delft (the Netherlands).

Lessons Learned CHARM Project

On 29 September 2023, we are ready to present the lessons learned and other results of CHARM during the final CHARM meeting. This will take place in Paris, France.

News

During the period of five years (2019 - 2023), CHARM has developed interesting demonstration exemplars. These demonstration exemplars were executed by social housing organisations Leefgoed in Belgium, GreenSquareAccord in the United Kingdom, and Paris Habitat in France. They were supported by Kamp C, University of Birmingham and TU Delft. Co-partner of CHARM is l'union sociale pour l'habitat. Project CHARM is funded by Interreg NWE and financially supported by Provincie Noord-Holland.

In these five years, things have changed. There were mergers and one of the demonstration exemplars was replaced by another one (due to external circumstances). However, the goal of our project remained: optimise the (re)use of material and natural resources. Another objective of the project is to demonstrate innovative approaches for housing renovation and asset management that prevent downcycling. And we did.

In the UK e.g., GreenSquareAccord has developed and built 12 social housing dwellings with about 85% less plastics than conventional houses. In Paris, social housing organisation Paris Habitat has built a Material Exchange Platform (MEP). This is an online platform where used materials can be traded. Also, they are renovating dwellings with used materials. And in Belgium, Leefgoed renovated their head quarters almost completely with the use of existing and used materials. These insights, knowledge and craftsmanship is now being used and applied in a renovation project of social houses.

You will find more detailed information on the results of the demonstration exemplars here soon. On 17 January 2024, lead partner of CHARM TU Delft presented the final project result summary during a webinar, hosted by project partner EFL. You can find the CHARM project result summary here.
