In the heart of London, close to the Bank of England and St Paul’s Cathedral, you will find two giant, bronze-clad office buildings linked by bridges.
The construction, which is being hailed as an exemplar of sustainability, houses Bloomberg’s new £1bn headquarter. With their new office, Bloomberg sets high standards for large-scale sustainable office design and with automated natural ventilation from WindowMaster, we are proud to be part of this unparalleled project.
The 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.
Besides vacuum drainage, a combined heat and power system, an absorption chiller and a bespoke chilled ceiling, a hybrid natural-ventilation solution is used in the northern building’s atrium. Consequently, the nine-storey building is expected to use 35% less energy than a typical office.
In the new headquarters, outside air will enter the floor plates through the vertical bronze fins that line the building’s façade and frame the glazing. The fins incorporate acoustically treated vents that open and close to control airflow. From the floor plates, the air will rise and excess heat will be exhausted out of the central atrium.
The automated natural ventilation system will be applied in mid-season periods with milder weather while in the summer and winter, when the façades are sealed, the office will be mechanically ventilated. Reducing dependency on mechanical ventilation and cooling equipment significantly reduces energy consumption.
WindowMaster has supplied MotorLink Controllers to offer the best functionality for this high-tech building, along with over 800 black actuators of various types. The building was completed in October, 2017.
