Green roof

A green roof will be installed on the REC P building. We decided to do this because a green roof absorbs rainwater through the buffering of water in the plants, substrate and drainage layer. It slows down run-off to the sewage mains, purifies the rainwater and enables evaporation through the plants. This keeps the groundwater level stable and reduces the peak load on the sewage mains. A green roof also makes for cleaner air. The plants on a green roof filter particulate matter from the air and convert CO2 into oxygen. A green roof also provides a sound barrier around the building. It absorbs sound and creates a quieter environment, both inside and outside the building.

Circular renovation

Used materials from the former REC P are being reused as much as possible in the building. Materials that cannot be used are offered for sale on a special marketplace. In addition, building materials from other demolition/dismantling projects are being used. For example, we are reusing window frames, hardwood stairs, wood floor panels, concrete roof tiles and fixtures, and old doors that have been sawed up into planks are used as acoustic panelling.

Natural gas-free building and transport of building materials over water

Other action we are taking in order to carry out the project as sustainable as possible:

• REC P will be a natural gas-free building.
• Building materials are being supplied and removed over water in order to reduce the volume of traffic in the area.
• Hot water will be supplied through a central energy facility (CEF) that runs on geothermal heat by means of a thermal energy storage (TES) system.
• Energy-efficient LED lighting.
• Rooftop solar panels.
