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 objectives of project CHARM

The main project objective of CHARM is not only 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 organization 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


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.

International Social Housing Festival 2019

The International Social Housing Festival 2019 (4 - 8 June 2019) is linking the homes we inhabit, the cities we live in and the overall quality of life, the ISHF 2019 aims through a series of diverse events to highlight the importance of access to decent housing for all, to celebrate the long tradition of public, cooperative and social housing and its key role in addressing current and future housing challenges.

EU Sustainable Energy Week 

European Sustainable Energy Week (EUSEW) is a month-long series of activities to build a secure energy future for Europe. It brings together public authorities, private companies, NGOs and consumers to promote initiatives to save energy and move towards renewables for clean, secure and efficient power. Launched in 2006 by the European Commission, the EUSEW is organised by the Executive Agency for Small and Medium-sized Enterprises (EASME) in close cooperation with Directorate-General for Energy.

Amsterdam Smart City

Amsterdam Smart City is an platform that brings together citizens, innovative companies, knowledge institutions and public authorities to shape the city of the future. Amsterdam Smart City consists of a public private partnership and an international community. By sharing knowledge and by collaborating we come up with innovative solutions for metropolitan issues of a social, economic and ecological nature. This way we ensure that the Amsterdam Metropolitan Area remains liveable, now and in the years to come.

17 - 23 June 2019  We make the City Festival in Amsterdam

ZenN: Nearly Zero Energy Neighbourhoods

The research project ZenN aims to reduce energy use in existing buildings and neighbourhoods. The residential areas that are participating in the project and in conjunction with the renovation of these areas a number of specific measures will be implemented.

Solar Decathlon Europe

The Solar Decathlon was launched in 2000 as a challenge to university teams to design, build & operate highly energy-efficient & solar-powered homes. By generating widespread media coverage to reach millions of people, SD generated parallel power to educate the public on the benefits, affordability & availability of clean energy solutions.

TU Delft is in the competition of the Solar Decathlon with their MOR-team. MOR stands for Modular Office Renovation. Ultimate goal of MOR: creating a future proof built environment that gives back more to its surroundings than it takes away from it.

The Green Village

The Green Village is an innovation site where new technologies in the field of sustainable energy provision, water and waste systems will be tested and applied in a real life environment. One of its main aims will be to accelerate innovations in energy transition. The Green Village is a platform where knowledge institutions and companies will be able to jointly develop and valorise technologies and systems. TU Delft will create the basic facilities for The Green Village. The facilities will take the gradual commercialisation of The Green Village into account.


Energiesprong is a revolutionary, whole house refurbishment and new built standard and funding approach. It originated in the Netherlands as a government-funded innovation programme and has set a new standard in this market. The mission of Energiesprong International is to scale this approach to other markets.

Energiesprong uses the social housing sector in each market as the launching market for these solutions, with a view to later scale to the private home-owner market. The independent Energiesprong market development teams aggregate mass demand for high quality retrofits (and new built houses) in a market and creates the right financing and regulatory conditions in parallel. With this in place, solution providers can go into a quick and transformative innovation process to deliver against this new standard.

Vlaanderen Circulair/Circular Flanders

Circular Flanders is the hub and the inspiration for the Flemish circular economy. It is a partnership of governments, companies, civil society, and the knowledge community that will take action together.


The URBACT programme has been the European Territorial Cooperation programme aiming to foster sustainable integrated urban development in cities across Europe. It is an instrument of the Cohesion Policy, co-financed by the European Regional Development Fund, the 28 Member States, Norway & Switzerland.

URBACT’s mission is to enable cities to work together and develop integrated solutions to common urban challenges, by networking, learning from one another’s experiences, drawing lessons and identifying good practices to improve urban policies.

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.


Partners of project CHARM

The social housing organisations involved in Interreg NWE project CHARM are: Zonnige Kempen from Belgium, Paris Habitat from France, Stichting Woonbedrijf SWS.Hhvl from the Netherlands and Accord Housing Assocation from the United Kingdom. 

Lead partner of project CHARM is Delft University of Technology. The project is actively supported by: European Federation for Living (EFL), Kamp C and the University of Birmingham.
