Standvast Wonen built 74 flats for senior citizens in Nijmegen: independent social housing. Sustainability was a focal point; a heat and cold storage system supplies all flats with heat and cold via underfloor heating in the living room, bedrooms and bathroom.
With this project, housing association Standvast is responding to changing society. Older people are living independently for longer and longer, but are looking for a certain degree of protection and companionship. Together with the adjacent Huize Rosa care centre, the Tristan & Isolde residential towers form a care continuum in which elderly residents can live well together. Upon request, Huize Rosa can provide individual care at home for Tristan & Isolde residents.
The Tristan & Isolde residential towers were completed in 2011. Project developer and investor Standvast Wonen leases the flats to private individuals. The total gross floor area is 7,000 m2. Since 2015, Vaanster has been responsible for operating the WKO system.
"When we took over the management of the WKO system in early 2015, it was already clear that the system was not functioning properly. The system was unreliable and there was insufficient insight. We opted for a two-stage rocket: first get a good picture of the pain points, then look for targeted solutions.
The old system did not use integral control technology. This became one of our first improvements: adapt and expand the building management system. This adaptation significantly improved controllability. An additional advantage is that we simultaneously increased the efficiency of the WKO system.
In the quest to improve the WKO system, we worked with multidisciplinary teams. By centralising knowledge and skills of all parties, we achieved a great result. The installation works without major problems and is perfectly manageable and controllable.
The residents also thought constructively with us. By looking along from the residents' point of view, the concerned chairman of the residents' committee contributed to the solution."
