Waterman in UK pilot of world-leading office energy rating scheme

Waterman is collaborating with Stanhope and Mitsui Fudosan UK on a new pilot programme which employs the principles of the NABERS (National Australian Build Environmental Rating System) scheme, a new development leading the world in providing high performance prime office space. 

Stanhope plc and Mitsui Fudosan have agreed to the use of the new Angel Court, Bank, office building in London for part of the study. 

Australia’s NABERS office energy rating scheme targets the in-use energy performance throughout the development process which is then verified by an investment-grade rating using 12 months of metered data. These ratings have been particularly successful for so-called base building services in large rented offices, typically under control of the landlord. The analysis of Angel Court follows a feasibility study, published in May 2016, which confirmed whether NABERS-style commitment agreements could work in the UK.

The 18-month pilot is led by Robert Cohen from Verco Advisory Services and supported by Bill Bordass from the Usable Buildings Trust. Waterman’s building services teams in London and Australia have been appointed to test a ‘design for performance’ approach in UK prime rented office developments, validating a building’s energy consumption compared to that declared at design stage. Waterman’s certified NABERS assessors in Australia will be reviewing the project thermal modelling and providing a performance rating for the development in advance of occupation, as well as providing input on ‘lessons learnt’ when handing over and monitoring buildings in use. 

Waterman director Mark Terndrup commented: “This pilot means that office buildings across the UK can achieve more accurate predictions of thermal models which has historically been a challenge. Differentiating base building energy use from that used by occupiers has provided a focus for stakeholders in Australia and has allowed the market to drive improvement. We are convinced the same potential exists for the UK market place.” 

Angel Court was designed by Fletcher Priest Architects with MEP, structural and environmental multidisciplinary services provided by Waterman Group.
