Some are calling One Angel Square in Manchester ‘the most environmentally-friendly building in the world', and it might be true considering it's the highest scoring BREEAM building. The new headquarters for the Co-operative Group boasts a number of sustainable strategies including a high performance, double-skinned facade, earth tubes for heating and cooling, rainwater harvesting and much more. 3DReid, the architects behind the project, even went so far as to future-proof the building in anticipation of a three to five degree increase in summer temperatures and a 30 percent increase in winter rainfall. The building was completed this year and it officially opened with the help of the Queen during a royal visit.
One Angel Square is a 500,000 sq ft, 14-story building right in the downtown of Manchester.
Now the largest building in the city, it is part of a larger effort to redevelop the core and is strategically located to Victoria Station, the city's major commuter hub
3DReid and the Co-operative Group were aiming high from the start to create highly sustainable building.
With it's completion in the middle of 2013, One Angel Square was awarded BREEAM Outstanding with a score of 95.16%, the highest ever.
Her Majesty The Queen, accompanied by His Royal Highness The Duke of Edinburgh, visited the office building on November 14th to officially open it to the public.
Employees of the Co-operative Group line the balconies to celebrate the opening of the building.
Euan Sutherland, The Co-operative Group Chief Executive said: “From the outset the Group set very high aspirations for the green credentials of the new building but for One Angel Square to be recognised as the most environmentally friendly building in the world is a truly remarkable achievement. The visit today of the Queen and The Duke of Edinburgh symbolises the completion of the building and one of the most significant UK construction projects in the past five years.”
Compared to its old headquarters, One Angel Square reduces energy use by 50% with an 80% reduction in carbon emissions. This is achieved through a highly engineered design relying on passive solar, thermal mass, innovative materials and efficient systems.
Massing, orientation, solar shading and the double-skinned facade work to provide daylighting without overheating, while thermal mass soaks distributes heating (or cooling).
Earth tubes use geothermal energy to provide energy efficient heating and cooling with the help of a CHP biomass system.
Water efficient fixtures, rainwater harvesting and greywater recycling all work together to reduce water usage.
Beyond the sustainable building strategies, the Co-operative Group has also instituted operational changes to help reduce their carbon footprint like a green travel program and personal carbon trackers.
With the award of the BREEAM Outstanding certification, the project is being heralded as the most eco-friendly building in the world.
