Platform on new construction, renovation, restoration and transformation
To this end, innovative steps were taken particularly in the steel construction. This is coated with Biocoat® and can eventually be easily dismantled and reused.
"Building a fully circular building had been on our wish list since 2016," says Aniek Averesch, project consultant at Circular Steel. "Circular building, however, has only been taking concrete form for a year. We started looking for a builder who wanted to co-develop the concept and a user who wanted to embrace our ambition." With the steel concept of Brink Staalbouw 'Circulairstaal', Metron Vastgoed and Aan de Stegge Twello, the new building plan for DAVO Publishers came on the table for an optimally circular company building.
Three pillars were always central to the development of the building. The building had to be reusable, detachable and with minimal environmental impact. It required an intensive search to gather the appropriate products and concepts. "Ultimately, the building materials used for 80% are circular," says Teun Wesselink, technical project manager at Aan de Stegge Twello. "The remaining 20% is in the foundation. Not fully circular, but very low CO2."
Particularly innovative steps were taken with the steel structure. The design took into account from the very beginning that the structure had to be fully dismantleable and reusable for other purposes after a period of time. Therefore, the steel elements were not welded together, but connected with bolted joints. This approach also reduced CO2 emissions. The traditional, color-bound coating was replaced by a protective Biocoat®, a durable and transparent powder coating.
Circular Steel and all other shell suppliers provide a buy-back guarantee on the materials. This also makes the project unique. By registering all used materials and agreeing on take-back guarantees with the suppliers, there remains long-term visibility on the raw materials used and they can be reused when demolished. In addition, the building remains worth more money because parts do not have to be demolished but can be reused.
However ambitious, circular steps are not always enthusiastically received yet. "In most cases the focus is on BREEAM; circularity still remains a tricky item," Averesch says. "Steel construction companies see reuse as a threat to their services. DAVO's circular commercial building has accelerated the acceptance process. The building is already serving as an example for other circular new construction projects."
