The desire to create a highly innovative, sustainable building was central to the original design brief for architects 3DReid and the
The focus on sustainability has been embedded at the heart of the project and has shaped all of the core activity – impacting everything from choosing the initial location for the building, the architectural design, throughout the construction process and has also influenced how The Co-operative Group will occupy the building in its entirety.
The building will be powered using a pioneering, bio-fuel cogeneration plant oil fed combined heat and power (CHP) system. Rapeseed oil, which is being grown on The Co-operative's own farmland, will be used to run the engine. Rainwater and greywater harvesting has been employed to guarantee low water consumption and the building has many ground breaking engineering features, including a double skinned façade to minimise heating and cooling throughout the year. Geothermal earth tubes to circulate fresh air and chilled beams throughout to provide natural cooling.
One Angel Square will operate with at least an 80% reduction in carbon emissions and a 50% reduction in energy consumption compared to the current Co-operative head office complex, which in turn will save the Group over £500k per annum.
As occupiers, The Co-operative Group have seized the opportunity to introduce a programme of organisational transformation to ensure the building is used in a sustainable way including creating a green travel plan for the site and rolling out virtual desktop technology that not only uses less heat and energy but will also enable flexible working, including home working and hot desking to drive maximum space efficiency.
