WHAT IS THE PERFORMANCE GAP?

The built environment is currently facing a huge challenge. On average, buildings are currently consuming between 150% and 250% their predicted energy and carbon values. This problem is known as the performance gap: the difference in energy use and carbon emissions of non-domestic buildings, from design prediction to performance in use. In some cases, this gap has added over £10/m² in unexpected annual operating energy costs.

There is growing evidence that current legislation is not achieving expected reductions in the actual energy use of buildings, leading to unintended financial and environmental consequences. Buildings continue to use energy and carbon unsustainably, despite current and emerging knowledge and practices that can deliver highly efficient and sustainable buildings.

The typical risks of underestimating the likely energy consumption of buildings is significant. We label these risks collectively as 'unregulated' because mandatory compliance calculations do not account for occupant-related energy use.

WHY DOES THE GAP OCCUR?

The gap can occur for a number of reasons: from inaccuracies during the design process, to design changes or poor quality of construction, to inadequate commissioning or systems not operating as intended once the building is in operation.

While leading portfolio holders are taking notice of the commercial risks associated with ‘low carbon’ buildings, a lack of cross-sector data sharing, building performance knowledge, design, technology and refurbishments mean many buildings fall short of performance expectations.

CLOSING THE GAP

The key to bridging this performance gap lies in the provision of robust data and the closure of the ‘feedback loop’ along each stage of the building lifecycle . The solution to delivering buildings at optimum performance therefore relies on the transparent sharing of knowledge and data through the life of the building, and a single platform for cross sector collaboration using a common metrics.

And that's where we come in!

As a not-for-profit initiative, our mission is to provide property professionals with the tools to understand and validate energy and carbon data, to reduce the performance gap in buildings... so that every building will have no disparity between design prediction and operation, resulting in a truly sustainable built environment.

We do this through our four service offerings: Briefings and events, Bespoke advisory, collaborative research and training led by property professionals.
