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


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.

100 Resilient Cities

100 Resilient Cities is dedicated to helping cities around the world become more resilient to the physical, social and economic challenges that are a growing part of the 21st century. 

Cities face a growing range of adversities and challenges in the 21st century. From the effects of climate change to growing migrant populations to inadequate infrastructure to pandemics to cyber-attacks. Resilience is what helps cities adapt and transform in the face of these challenges, helping them to prepare for both the expected and the unexpected.

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.

Convenant of Mayers for Climate & Energy

The EU Covenant of Mayors for Climate & Energy brings together thousands of local governments voluntarily committed to implementing EU climate and energy objectives. The Covenant of Mayors was launched in 2008 in Europe with the ambition to gather local governments voluntarily committed to achieving and exceeding the EU climate and energy targets.


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.

Energy Cities

Energy Cities is the European Association of local authorities in energy transition. The association has been created in 1990 and represents now more than 1,000 towns and cities in 30 countries. Main objectives are: 1) to strengthen the role and skills in the field of sustainable energy; 2) to represent the interests and influence the policies and proposals made by European Union institutions in the fields of energy, environmental protection and urban policy; 3) to develop and promote initiatives through exchange of experiences, the transfer of know-how and the implementation of joint projects.

C40 Cities

Around the world, C40 cities are taking bold climate action, leading the way towards a healthier and more sustainable future. C40 cities have tremendous power to act on climate ambitions -- and their power only grows when they work together. The C40 network facilitates dialogue amongst city officials. This builds trusted relationships, which in turn ensures that ideas, solutions, lessons, questions, and even friendly competition can flow freely and responsively to cities' needs.

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.
