Sustainable renovation of the existing housing stock is currently one of the biggest challenges for the construction sector.
In this publication, we show the material-related CO₂ emissions of renovation projects and how these emissions can be reduced. By analysing eleven conventional renovation projects (100,000 m² GFA) in the Utrecht region, we gained insight into current emissions, the potential of reused and biobased materials, and the financial implications of circular measures. The report also highlights the risks of continuing to rely on traditional construction materials, such as uncertainty in supply chains, price fluctuations, and risks to human health.
The research underlines that steering toward minimal material-related CO₂ emissions, incorporating a fair CO₂ price in decision-making, and fostering collaboration between government, clients, and builders are essential for an effective and future-proof renovation approach.
Involved parties
Commissioned by the Province of Utrecht and DigiC (ROM Region Utrecht), Copper8 and W/E consultants conducted research into the CO₂ impact of eleven renovation projects in the Utrecht region. Information and project data were provided by market parties: Coen Hagedoorn Bouw, Dura Vermeer, Elk Groep, Hemubo, Van Wijnen, and Rutges vernieuwt.
What’s next?
There is strong willingness to get started with circular renovation. The various stakeholders can begin with several concrete initial steps. At the same time, it is necessary to work toward creating the preconditions needed to establish a level playing field for circular products and materials in renovation projects. The publication offers guidance on how to move forward.
