Only by truly understanding your operation can an energy manager provide accurate and actionable savings. We will establish your significant energy users (SEUs), assess and log your operation and calculate savings made available through the introduction of measures, technical installs, building fabric improvements, controls and behaviours. Once we’ve addressed your operation, we will also assess opportunities for renewable and low carbon energy and fleet alongside energy storage and on-site capacity.

By assessing your data and bench-marking against both yourselves and good practice, we are able to establish indicative savings potential. We can then assess and profile your site, equipment, operation and controls, and make calculations to establish actual energy, fuel, carbon and cost savings available. We will then make bespoke and specific recommendations to your organisation setting out internationally (IPMVP) recognised, guaranteed minimum savings.
