Rijkswaterstaat DI is a governmental agency that handles public works and water management for the Netherlands – including the construction of waterways and roads and flood protection and prevention. Made from prefab concrete, the ground floor offices of Control Building Volkerak Locks are covered with a rich grass roof that acts as a natural insulator. The upper levels are made from a timber and glass, allowing people inside to have a clear view of the water locks and the building’s surrounding landscape.
Well-orientated and protected from excess solar radiation, the building keeps its south facade and roof closed. These elements were built slightly apart from the building, generating an air current that brings cool in to ventilate the interiors. The Control Building uses a heat pump connected to the water lock to help regulate the interior temperature all year round.
