Eneco - Energy Service Company (ESCo) for Kunsthal Rotterdam

Wednesday, September 2, 2015

“This is just the start. Over the next 15 years, the consortium will enjoy a close working relationship with the Kunsthal. We will be continually assessing the way in which the building can be designed more effectively or intelligently. Each partner, on the basis of their own individual expertise, will be monitoring and analysing the situation so that together we can harmonise our innovative capabilities. What’s more, we have a joint incentive to bring about additional savings.”

-Dick van Veen, director of Sustainable Property at Eneco Business.

 

Purpose of the project
The Kunsthal Rotterdam is an iconic edifice designed by the illustrious Dutch architect Rem Koolhaas. It hosts a surprising range of exhibitions targeted at a wider public. One of the most popular cultural establishments in Rotterdam, the Kunsthal puts on an average of 25 exhibitions per year, pulling in around 180,000 visitors. Plans to modernise the building for a more sustainable future came about against the backdrop of a rapid rise in energy costs. When the building was designed in 1992, sustainability didn’t feature high on the agenda. From a climatological point of view, the entrance, reception area and exhibition galleries formed a single large space through which visitors could pass without any obstacles. With energy efficiency as the main goal, overdue maintenance has been carried out and functional adaptations made to improve operational management of the Kunsthal building.

Approach
Energy company Eneco, construction company Dura Vermeer and building engineering systems expert Roodenburg together form the consortium which is working with the city of Rotterdam (owners of the building) and the Kunsthal to renovate the building to meet the requirements of the present-day. The consortium developed an innovative business model - the ‘maintenance and energy performance contract model’ - on the basis of which energy-saving measures will be pre-financed by Eneco. The consortium will then take on responsibility for managing the building at a fixed price for the next 15 years. The amount is all-inclusive: from leasing costs, maintenance of the engineering systems and laundering to waste and cleaning services. To this end, a ‘performance’ will be delivered, instead of a service and they will be taking on the risks of the client. A fixed charge has been determined in advance for the whole operational management of the building. All consortium members are willing to invest in order to make a success of the project. If targets are not met, they will collectively bear the costs for any (financial) liabilities. The modernisation programme will be financed by savings in energy bills.
Amongst other things, the raft of measures consists of adaptation and stabilisation of (de)humidification systems, the application of heat recovery, adaptation of the lighting systems, installation of HR++ glass and building compartmentalisation.

Results 
By careful scrutinisation of all the systems and, where necessary, their replacement and by improved insulation and optimisation of energy efficiencies, the Kunsthal will now have energy bills reduced by 29%. Substantial energy savings will be made with respect to demand for heat.
In addition to savings in energy consumption, the consortium has also taken stock of the operational possibilities of the Kunsthal and implemented functional improvements.
As a result of the improved internal climate (humidity and temperature), it is now possible for the Kunsthal to attract collections of works that have specific climate requirements. In turn, this will have the effect of boosting visitor numbers.
