Decarbonisation of buildings

Considering the growing demand for energy in buildings and the expansion of the building sector, it is crucial to reduce its carbon footprint. This can be achieved through the implementation of energy-efficient technologies, the use of low-carbon building materials in which green concrete will be an important factor, and the adoption of renewable energy sources. At Cordeel, we are aware of the challenge and see the many opportunities and devolved several solutions to tackle the problem.

We believe that buildings are material banks for the future.

As one of the first Belgian companies, we have incorporated Madaster to create material passports for our projects. By registering building materials on the platform, we can automatically create a unique material passport for each building. This passport shows comprehensive information about the materials and products used, their impact on circularity and the environment, and the potential residual value they hold.

Green concrete

Structural components like columns, beams, walls and floors have a significant impact on the embodied carbon of buildings. We aim to industrialise the building process as much as possible and use concrete precast elements for structural components, prefabricated by C-concrete.

Our aim is to reduce the use of cement, which is responsible for 7% of the global CO₂-emissions, as much as possible. We have developed alternative concrete mix formulas with a lower cement content, reducing CO₂ emissions by over 650 tons (-7.4%) in 2022. We optimize our concrete mix by using alternative binders, substitute materials, and optimizing particle sizes. We also recover granulates and optimize local sand and aggregate use to reduce transport emissions.
