How to prove energy savings your finance team will accept
Finance teams have heard savings promises before. Three things separate credible claims from marketing:
- Baseline — agreed period, normalised for weather or trading where relevant
- Measurement route — meter, sub-meter or calculated verification method defined upfront
- Site context — what changed, what didn't, and why the figure is attributable
Every item in a Green Wing Discovery Assessment Report and Roadmap includes all three before it becomes a recommendation. That is how savings stay credible after the work is done — not just at sign-off.
