Foster + Partners-designed Bloomberg London office is world’s most sustainable

Bloomberg‘s new London-based headquarters for Europe has achieved an ‘Outstanding’ rating under the BREEAM sustainability assessment method, with a 98.5% score – the highest design-stage score ever achieved for a major office development, Construction Week reported.

Design by Foster + Partners, the Bloomberg HQ will deliver a 73% saving in water consumption and 35% saving in energy consumption and associated CO₂ emissions, compared to a typical office building.

These savings are being delivered by a range of innovative features, including distinctive bronze blades on the building can also open and close in ambient weather conditions are temperate to allow natural ventilation through the structure.

Internally, smart CO2 sensing controls will allow air flow to be dynamically adjusted to match the number of occupants in the different areas of the building, resulting in savings of 600-750 MWhr of power per annum, and a reduction in CO2 emissions of approximately 300 tonnes each year.

Integrated petal-shaped ceiling panels will meanwhile combine all HVAC, lighting and acoustic functions, and use of 500,000 LED lights to deliver a 40% lower energy demand than a fluorescent office lighting system.

Norman Foster, founder of Foster + Partners, commented: “The deep plan interior spaces are naturally ventilated through a ‘breathing’ façade while a top lit atrium edged with a spiralling ramp at the heart of the building ensures a connected, healthy and creative environment.”

Features such as the central ramp, which spans six floors, will encourage workers to move through the building on foot, and are complemented by sit-to-stand work stations for all employees, two cycle centres and a wellness centre incorporated on-site health services.

An efficient on-site combined heat and power generation centre is also expected to save 500-750 metric tonnes of CO2 each year, while a rainwater and greywater recycling system will also save 25 million litres of water each year, enough to fill ten Olympic swimming pools.

Alan Yates, technical director of BRE Global’s Sustainability Group said: “What sets the Bloomberg building apart is its focus on innovation and its holistic approach to sustainable construction and design. Projects like these are really important in giving confidence to the industry to experiment.”

Across Bloomberg’s operations, environmental impact management has helped the company to eliminate nearly 700,000 tonnes of CO2e (41% of CO2e intensity reduction) and avoid $95m in operating costs since 2008.

Bloomberg has also been a zero-landfill operation in London since 2010; instead, waste is recycled, composted or converted to energy. Globally, Bloomberg currently diverts 75% of its total waste away from landfills and is targeting 90% diversion by 2020.

Michael Bloomberg, founder of Bloomberg said: “We set out to push the boundaries of sustainable office design, and to create a place that excites and inspires our employees, and I hope we’ve set a new standard for what an office environment can be.”

With the addition of the new London building, Bloomberg will have 34 LEED or BREEAM-certified projects globally.

By the end of 2017, nearly 70% of the company’s 19,000 employees will occupy an environmentally certified office.

Foster + Partners is also designing the Middle East’s first design institute, DIDI, which will be completed next year.
