The NABERS rating scheme, which already operates in Australia, aims to bridge the gap between the design and in-use energy performance of UK offices.
NABERS Energy ratings measure and verify the actual energy use of existing offices, providing a rating from 1-6 stars and helping building owners to accurately target, measure and communicate the energy performance of their buildings.
This investment grade rating can be used to demonstrate whether offices are on a net zero carbon trajectory and provide investors and occupiers with the confidence that the buildings they own and occupy are aligned with their climate change ambitions.
As part of NABERS UK, developers will also be able to use the Design for Performance process to target a NABERS Energy rating at the design stage of a new office development or refurbishment and verify performance when the building is occupied, overcoming the well-evidenced performance gap between design and operation.
This approach is already being pioneered by 12 major UK property owners on new office developments totalling over half a million m2 across the UK.
The NABERS UK scheme has been developed via the Design for Performance initiative led by the Better Buildings Partnership (BBP), working in close collaboration with the market transformational Australian NABERS programme. That has resulted in a billion dollars saved in energy bills over decade and seven million tonnes of CO2.
The work has been funded by British Land; Derwent London; Federated Hermes / MEPC; Great Portland Estates; Grosvenor Britain & Ireland; Landsec; Legal & General Investment Management; Lendlease; Nuveen Real Estate; Royal London Asset Management and Stanhope, and backed by industry bodies including the British Council for Offices; British Property Federation; BRE; BSRIA; CIBSE; CREFC Europe; RIBA; RICS; UKGBC and the Usable Buildings Trust. The scheme was developed for the UK market with expert input from Verco & DeltaQ.
NABERS is a huge leap forward for the industry in measuring and verifying the actual energy performance of UK officesSarah Ratcliffe, BBP
The scheme will be governed by a Steering Committee comprised of NABERS, BBP and BRE, who in a recent development have been confirmed as the NABERS UK administrator and will be responsible for assessor training and building certification. These founding members will be joined by other stakeholders early in 2021, representing industry bodies, scheme users and technical experts from across the property sector.
The launch of the scheme comes at a critical time for the industry, with the UK government’s consultation on energy performance disclosure for commercial buildings expected before the end of the year. Yesterday (25 November, 2020), the UK government also published its National Infrastructure Strategy, which sets out how the UK will boost the economy and meet the UK’s net zero emissions target by 2050.
Sarah Ratcliffe, CEO at BBP said: “The launch of NABERS UK marks a significant milestone for this project, but more importantly a huge leap forward for the industry in measuring and verifying the actual energy performance of UK offices. This has been a truly collaborative effort from across the industry over many years. I am absolutely delighted that we now have a scheme in the UK that will transform the market for better, more energy efficient offices.”
Shamir Ghumra, Head of Building Performance Services at BRE, said: “Administering NABERS UK will allow us to deliver greater performance improvements in the construction and upkeep of commercial offices. With sustainability firmly on the agenda, and COP26 on the horizon, 2021 is set to be an important year in the global fight against climate change and I am delighted that by collaborating with NABERS, BRE will continue to play an important role in this challenge.”
