Bloomberg’s new European headquarters—billed as the “world’s most sustainable office building”—opened yesterday in London. Designed by Foster + Partners, the 3.2-acre Bloomberg HQ achieved a BREEAM Outstanding rating with a 98.5% score that the architects say is the “highest design-stage score ever achieved by any major office development.” The nine-story headquarters is estimated to save 73 percent in water consumption and 35 percent in energy consumption when compared to typical office buildings.

Clad in nearly 10,000 tonnes of English sandstone and bronze, the massive Bloomberg HQ mitigates its size by carving out a public pedestrian arcade between its two buildings, while bronze fins give the buildings human scale and also allow for natural ventilation and protection from solar gain. Located between the Bank of England and St. Paul’s Cathedral, the city block-sized development is also meant to blend in with and respect its historic surroundings. In addition to the pedestrian Bloomberg Arcade, the building features three public plazas and ground-floor restaurants to engage the urban fabric. Site-specific art installations, from artists like Cristina Iglesias and Olafur Eliasson, punctuate the development.

“From day one, we talked with Mike Bloomberg about creating an elegant stone building that responds to its historic setting yet is clearly of its own time and which would be a good neighbour in the City of London in every sense of the word,” said Lord Foster, Founder and Executive Chairman, Foster + Partners. “We wanted the building to have an integrity and continuity of expression both inside and out, creating an inspiring, innovative, dynamic and collaborative workplace for Bloomberg that embodies the core values of the company. Above all, we had a shared belief with Bloomberg that we should provide the highest standards of sustainability and wellbeing for its occupants, as well as create major new public spaces at ground level, making a significant contribution to the daily life of the City of London and its inhabitants.”
