If a developer goes to all the trouble of building an office cloaked with 350,000 plants, then that greenery had better be more than skin deep. Fittingly named Eden, this 12-storey office, which stands out among the grey, metallic and dull red brick colours of Salford, is the first building in the UK to feature a NABERS UK 5.5* design review rating. 

NABERS is the energy efficiency rating system that is gaining traction because it is a proven methodology for predicting energy performance which is subsequently vindicated with annual energy consumption monitoring.
