The very first version of a green electricity roof has been placed on the NIOO building in a distant past (2011). After years of data collection and other research, this system was later completely replaced by a commercial system with lights. The NIOO is, as the first Plant-e ambassador, still a valued partner.
When the research system from Berkel & Rodenrijs had to make way for a roundabout, the NIOO agreed with the relocation of the research into their ditch. As a result, precious data has fortunately not been lost.
