“Architects have a responsibility towards the environment.” That is quite a statement coming from Reginald Schellen, owner of architect company Schellen Architecten. “We need to do something to stop this earth from heating up,” he explains. “And we can contribute by building energy-neutral buildings.”The design of every building in the hands of Schellen is as energy neutral as possible. They work with the principle of the Trias Energetica, which means they waste as little energy as possible. The energy that is used is mostly sustainable and the fossil energy the buildings douse will be as efficient as possible. Therefore, elements like heat pumps and solar panels are used. “We do this with every kind of building we design. Whether it’s an office, apartment, villa, health facility or sports complex.”
