The glass skin of the building is designed to reflect the Dutch skies. The panels of fused glass with lens-like spheres reference a vernacular window design that can be seen throughout the historic city. The combination and rhythm of open panels of high performance glass and closed fused glass panels enable a high degree of energy efficiency. Throughout the design process the building volume has been shaved and reformed to create a compact, highly efficient building form. The lowered roof lines at the corners provide a gradual transition towards the existing small-scale development of the Delft city centre and the adjacent Wester Quarter.
The facade responds to the different sun orientations, which determined the amount of glass incorporated, thus mitigating daylight needs while reducing heat gain in the summer months. The glass has a high light absorption factor but low solar absorption, and all windows can be opened manually for user comfort and natural ventilation. Solar panels on the roof provide 20% of the energy for the building mechanics and presence aware lighting. The GreenCalc+ score is rated at 270. Source by Mecanoo.
