The first Nabers UK energy rating that takes into account operational performance has been awarded to an office in Leeds owned by developer Grosvenor.

Nabers UK is adapted from the ratings programme developed in Australia more than 20 years ago, and is already being used to inform the design of buildings under construction. It gives ratings ranging from one star to six stars, based on the measured and verified energy use of operational offices,

The eight-storey, Grade A Toronto Square office building in Leeds city centre – which was refurbished in 2009 – has been rewarded a 4.5 star rating after analysis on 12 months’ data. The data for the building was collated and analysed by EP&T Global, a Nabers UK licensed assessor, and independently certified by BRE.

Nabers UK ratings have to be measured and verified every 12 months, and demonstrate whether offices are on a net zero carbon trajectory, They give investors and occupiers confidence that the buildings they own and occupy and aligned with their climate ambitions.

The Toronto Square rating will provide more information on the building’s performance, helping Grosvenor work with its occupiers to target additional improvements.
