Eden is a speculative, 12-storey office development on the English Cities Fund’s (ECF) New Bailey, Salford Central scheme. ECF has a vision for the project to be as sustainable, energy and carbon efficient as possible, increasing biodiversity and creating a positive impact on society. The scheme is targeting net zero carbon in operation and has been designed in line with the UKGBC Net Zero Carbon Framework Definition. The building is the first new build in the UK to achieve a 5.5 NABERS 'Design Reviewed' Target Rating with an upfront embodied carbon of 620kgCO2/m². Eden is also set to be BREEAM Outstanding and WiredScore Platinum.

Embracing the WELL Building Standard principles, we developed a holistic sustainability strategy to deliver a building that is net zero carbon in operation and designed to enhance occupancy health, wellbeing and productivity. The design includes a living façade that will remove air pollutants, reduce urban temperatures and improve biodiversity, while providing biophilic health and wellbeing benefits to the users.

Simon Wyatt, Partner, commented, "Cundall is committed to pushing the boundaries in the development of sustainable buildings. We are proud to have played a critical part in ensuring this building design meets its many sustainability targets, including the UK Green Building Council net zero carbon operation 2030 targets. It is exciting to now follow the project’s progress and see its potential come to fruition."

One of the greatest challenges was ensuring that requirements for operational energy, embodied carbon and biodiversity net gain were written into the building contract in a meaningful way, with a clear methodology for measuring, reporting and certifying performance in use.
