In 2016 the final phase of the renovation of the RDW office (The Netherlands) was realized. The new concept focused on energy efficiency, health and flexibility. The renovated RDW building had to be at least 40% more energy-efficient with energy label A+. This has been realized with energy-efficient fans, standard WTW unit (Topvex FC) and modular air handling units (type HHFlex). Systemair has also been able to supply the fire dampers.
