The Real Estate Environmental Benchmark (REEB) is a publicly available benchmark of operational environmental performance for commercial property in the UK. It is one of the only benchmarks based on the performance of buildings ‘in-use’ and is increasingly becoming the industry standard used by investors, fund managers and property owners to compare the performance of commercial properties across the UK.

Based on the annual utility consumption data of the commercial property portfolios of BBP members, this report provides energy and water performance benchmarks for offices, shopping centres, retail parks, leisure parks and car parks, which can be used by others to compare the performance of their buildings.

The benchmarks provide one of the most up to date reflections of industry performance; the benchmarks are based on a 3-year rolling average and are updated each year. Details outlining how the benchmarks are calculated are provided at the end of this report.

The REEB dataset is one of the most comprehensive concerning performance in-use. With the permission of BBP members, the data is made available on an anonymous basis to support a wide range of research projects in this important field.
