Grainger ESOS Assessment.

Small smart changes = big savings.

The importance of data in driving a new cultural emphasis on energy saving across an organisation cannot be underestimated. We were appointed to work with Grainger plc, one of the UK’s largest professional landlord companies, to help it meet the Energy Savings Opportunity Scheme (ESOS) assessment.

Putting it into practice.

With an impressive portfolio of office and residential buildings, Grainger not only wanted to meet the assessment requirements, but also help develop its sustainability strategy. This involved undertaking nationwide energy audits on multiple properties, including its head office and high-profile residential buildings, along with an assessment of transport energy use.

An additional challenge on this project was providing practical and meaningful energy analysis and savings recommendations that could be implemented across Grainger’s ever-growing portfolio. We worked closely with the Director of Strategy and Change to define our approach and gain a clear understanding of what needed to be delivered.

A tactical approach.

The first step was to identify, in collaboration with the client, the buildings consuming the highest levels of energy. The energy-reduction opportunities we identified in these particular buildings – such as lighting controls/LED, heating controls, and automatic metering – could then be implemented across the wider portfolio. Once this was complete, we produced a league table of Display Energy Certificates to showcase the performance of each office.

We also undertook an in-depth analysis of energy data provided for buildings and transport to identify any gaps in data and anomalies in recorded data. The outcome was a new cultural emphasis on energy saving across the organisation, bringing both commercial and environmental benefits.
