I've done a number of energy surveys for a big energy user and there are a lot of opportunities to improve their performance and realise a significant saving. I produced a few slides as a summary of my findings. Let's hope they move to phase 2!

1. Energy Survey
Overview

2. Sites Surveyed
Site 1 Site 2

6. Next Steps
Client to agree to move to next step
Return to four sites with specialists to produce accurately costed
proposals
Undertake Air Conditioning Inspections to ensure compliance with
the Energy Performance of Buildings Directive across portfolio
Appoint Dedicated Energy Management Resource conversant with
ISO50001
Initiate Energy Awareness Campaign

7. Potential
A saving on total energy costs of
between 20 and 30% can be
achieved at each site
