LES-TER

The Landlord Energy Statement (LES) and Tenant Energy Review (TER) is an innovative measurement system developed by the British Property Federation with the support of The Carbon Trust.

The Landlord's Energy Statement draws together the landlord's annual energy data, converts it into CO₂ emissions, and reports it in a standard format with a set of performance indicators. The LES takes account of any on-site renewable energy generated and, separately, it reports other measures undertaken to minimise emissions, including off-site generation, accredited 'green' fuels and carbon offsets. The LES also allows current performance to be compared with the previous four years.

Combined with data on their direct energy supplies, this can provide the whole picture, sufficient for the creation of a Display Energy Certificate. The availability of LESs will also encourage less environmentally-aware tenants to think about their own energy consumption. Where landlords and tenants share information, the landlord can create a record of the energy performance of the whole building.

BeyondCarbon establishes LES-TER for individual buildings, and integrates it use into building management, contracting, and corporate reporting.
