What is Benchmarking?
Per Energy Star,
"The first step to saving energy at your building is to benchmark — that is, to measure and compare your building’s energy to similar buildings, past consumption, or a reference performance level.
Benchmarking turns the information on your utility bill into knowledge you can act on.
when you improve the energy efficiency of your building, you reduce the greenhouse gas emissions produced in powering your building, which helps in the fight against climate change."
