Secondary school Notre Dame is in the middle of the countryside and was built with respect for the environment. Sustainability and green are important to the school. Therefore, the educational institution chose an installation company that was equally modern and ground-breaking in its thinking: VanderLinden.VanderLinden has been involved with the building from the design phase. It built a ground source heat system as a sustainable solution for heat and cold storage and it also built all the other systems, often inside the building. On the roof there was room for solar panels and a green living roof of moss and sedum. After the construction phase, VanderLinden deals with the sustainable maintenance and management of the systems. For example, VanderLinden manages the climate-control system remotely and actively manages on reduced energy consumption. It also provides the school with periodic insight into the condition of the systems.
