We are excited to see the BRE extend the NABERS UK scheme to include Whole Building and Tenancy ratings under the recently released NABERS UK V2.0 launch. These two additional ratings will join the NABERS UK Base Buildings rating, launched in November 2020, and will complete the NABERS UK Energy for Offices suite.
NABERS UK is a simple, reliable and comparable system for rating the energy efficiency of office buildings across England, Wales, Scotland and Northern Ireland. Unlike design-based ratings, NABERS Energy ratings measure and verify the actual energy use of offices, helping building owners to accurately track and communicate the energy performance of their buildings.
Just as the Base Building Rating looks to assess only the Landlord responsible energy the Tenancy Rating allows for businesses to rate the space they occupy within a building. The Rating tool considers the Tenant responsible energy only and considers factors such as occupied area, occupancy hours and occupancy density to create a comparable metric of performance.
The Whole Building rating combines the Base Building and Tenancy rating to measure the whole building performance. Typically this will be used for single tenant occupiers however it offers an important alternative to Landlords whose buildings currently cannot obtain a Base Building rating due to lack of sufficient metering.
Through our experience, Watkins Payne can offer a wealth of advice for delivering a NABERS UK Energy Rating including offering the Accredited Assessor role required in order to conduct and issue a NABERS UK rating. We can also advise on if a building is NABERS UK “ready” by assessing its existing metering provision and building management policies along with providing advice on maximising a building’s rating. Our experienced Building Performance Engineers and Simulators can provide the advanced simulation modelling required to help predict a building’s future performance.
All three rating types can be targeted at the Design Stage by signing up to a Design for Performance Agreement and following the process detailed in the Guide to Design for Performance.
The UK has a design for compliance culture which has led to the ‘performance gap’ that exists between the original design intent and how a building truly performs in use. Design for Performance (DfP) is a process that overcomes this where a developer or owner commits to design, build and commission a building to achieve a targeted NABERS UK Energy rating.
Through our experience Watkins Payne can offer a wealth of advice for delivering a DfP scheme including the Independent Design Reviewer role. If you have a project which is looking to target a NABERS UK rating in design or is looking to sign up for a Design for Performance Agreement contact Watkins Payne to see how we can support your project through the process.
