Building B30, The Hague, The Netherlands
energy efficiency and legacy meet.
Building B30, the former Dutch Ministry of Economic Affairs, was transformed into a multifunctional governmental knowledge centre and think tank. Deerns designed the technical installations and building physics, changing the 1917 building from an uncomfortable space and an energy guzzler into the first BREEAM Excellent-certified national monument in the Netherlands. The installations, including low-temperature heating, were integrated into the existing architecture by utilising empty space in its construction, thickening walls, repeating historical building elements, adding flexible fabric installations to the vaults and erecting wooden meeting cubicles with integrated technology.
