De Vier Gravinnen is a residential care centre in Tiel. The floors consist of 192 flats and the ground floor is dedicated to business spaces for social and commercial entrepreneurs. The gross floor area is 20,000m2. Sustainability plays an important role at De Vier Gravinnen. Heat and cold is regulated via underground storage and the building has energy label A.
"The De Vier Gravinnen project was completed in 2011. SCW Tiel was responsible for the project development and SCW Energie was investor. The gross floor area is 20,000 m2 and the flats are leased to private individuals, STMR and SZR Zorgpartij. The operation of the WKO system has been in the hands of Vaanster since 2015. Vaanster takes all worries out of your hands regarding energy supply. The work is carried out in a timely, professional and regular manner. The quality requirements of the work and the organisation of the execution meet the set requirements and standards."
H.W.J. Suijdendorp, Director-Director SCW Tiel
The architects of De Vier Gravinnen have given new impetus to the Hertogen neighbourhood in Tiel by using the Italian city of Siena as a model for the design. Terra-coloured bricks, cream-coloured stucco, open connections and a 'plaza' where everyone meets. Obviously, Siena wins out in terms of atmosphere over this Tiel variant, but in terms of sustainability, De Vier Gravinnen triumphs.
In 2015, SCW asked Vaanster to take over the management of the WKO installation. In this construction, SCW remains the owner of the system, while Vaanster takes care of the technology, billing and all communication with the residents. This way SCW does not have the burden, but it retains control over the tariffs.
When Vaanster took over management of De Vier Gravinnen's WKO, it turned out to be malfunctioning energetically. Through hydraulic and control adjustments, gas consumption has dropped significantly compared to previous years. Supply reliability has also increased and cooling has improved. The modifications better achieve the primary objective: comfort for residents.
