Case history: Colt design input at UPC

Excellent in sustainability

The offices of UPC in Leeuwarden have earnt a BREEAM Excellent certification, the highest rating in the world’s leading environmental assessment. The building won this not only because it is highly energy efficient but also because it provides a pleasant and comfortable environment for its occupiers. Firelight and Coltlite glazed natural ventilators installed into a Colt  glazing system contribute to the high levels of natural light.

The project presented one additional challenge. Since the building is at two different heights, we had to calculate the air currents that would affect the ventilators on the lower roof, as the taller building could deflect the wind onto the lower roof, blowing any heat and smoke back into the atrium. We devised an ingenious and aesthetic solution that ensures the correct performance of the Firelights on this section of the building.
