Our approach
Start with the building.
Keep the evidence visible.
You need to know what is being installed, how the saving will be assessed and whether the result is strong enough to justify a wider project.
We start with a free survey. If a pilot is suitable, we discuss the scope and agree a measurement method before work starts. The comparison uses your meter readings, with relevant site conditions considered.
Your engineer and finance team have something concrete to review. A result from another building is a useful starting point, but your own evidence has to make the case.
