Project description
Two new, sixteen-storey oval towers, an underground podium structure with the main entrance, conference centers, and restaurant of the Netherlands Tax Administration, along with a parking structure for visitors.
Special details
An integral approach was taken to the design of the complex, with close collaboration between the architect, landscape designer, structural engineers, and facility services consultants. This led to innovative solutions.The construction of the first tower was completed before the second tower was started. The entire building team, including the client, was able to profit from this by learning from the first construction phase. As a result, the construction of the second tower went smoothly.
A highly flexible lighting control system is implemented in the buildings. The lighting is integrated with the climate management system. Another special feature of the lighting is that it is fashioned in a star shape. This creates spectacular effects for external viewers on dark evenings.
The complex has very energy-efficient facility services with an energy performance standard that is 25% lower than the current mandatory standard. The complex includes a separate energy building housing a combined heat and power plant. The podium structure has a roof pond, which is connected to the combined heat and power plant.
Fixed fins that seem to hover in space are attached to the façades of the two towers. Where light passes through the fins to the interior, patterns have been placed on the windows to diffuse the light. Both of these measures reduce the use of artificial light. Deerns' consultants also took on the task of furnishings the conference centers and restaurant.
