Primary School Eindhoven – Netherlands

First Performance-based contract for primary school ‘The Rainbow’ in NL offers fresh new perspective

De Regenboog Steiner, a primary school in Eindhoven, is the first school in the Netherlands to conclude a 15-year performance-based contract setting out agreements on maintenance, energy-efficiency and the building’s indoor climate. Director Emiel Link is extremely satisfied about the responsible ‘ESCo’ organisation. “Obviously, it was a big decision, but there’s a great deal of mutual trust between the parties and they’re here in the blink of an eye if anything goes wrong. Good service comes at a price, but we now have the certainty of a healthy school for years to come and even enjoy the financial freedom to fund future measures.”

VBS De Regenboog in Eindhoven is housed in a monumental school building from the nineteen fifties. The building was expanded and partially renovated in 2014 – 2015. These parts of the school building now have a pleasant indoor climate thanks to systems designed and installed by ESCo Ovvia from Veldhoven. Ovvia guarantees an optimal and energy-efficient operation of all climate control systems and a class B indoor climate in accordance with the standards for schools with low energy consumption and a healthy indoor climate, the so-called Frisse Scholen. These standards have been recorded in an innovative performance-based contract that also contains agreements on ensuring fresh air and effective energy conservation in the remainder of the building and agreements on user satisfaction. Emiel Link: „This performanced-based contract enables us to hedge specific risks. And during the first contract period the ESCO has already made several extra investments, such as LED lightning and solar panels.”
