Bloomberg building has a Breeam Outstanding environmental rating, with a score of 98.5% – the highest design-stage score ever for a major office development. It is designed to use natural ventilation for as much of the year as possible, when outside air temperatures are in the range between 10 and 26 degrees C. The natural ventilation is enabled by automatic openings integrated in the facade in the bronze shading louvers. The outlet is constituted by automated vents atop the central atrium.
