A free building energy assessment that says no when the answer is no.
Send the property details, and a utility bill if you have one. NOI reads the tariff and the load and returns a written initial review within 2 business days on whether LED, solar, battery storage, HVAC or EV charging is worth pursuing for that building.

Every way the building uses energy, in one review.
The bill and the tariff
Energy charges, demand charges and time-of-use structure, and which meters the owner pays.
Lighting and HVAC
Fixture types and hours, and the age and condition of heating and cooling equipment.
Roof, parking and service
Space for solar or a canopy, roof condition, and electrical service capacity.
Programs
State and utility programs open for the property type and territory, with their current status.
A written answer, then a deeper look only if it is worth it.
Initial review
A written read of the property within 2 business days of receiving the details.
If it looks promising
We name the specific data needed for a deeper assessment, which takes longer than the initial review.
If it does not
We say so in writing and explain why. The assessment is free either way.

Demand Charges Explained: The C&I Bill Line Storage Actually Attacks
Most commercial energy budgets are managed on cents per kilowatt-hour. The line that moves NOI is usually the one priced per kilowatt of peak demand.
Efficiency First: Why LED, HVAC and Controls Come Before New Generation
The cheapest energy is the energy a building no longer needs. Efficiency work also shrinks the system you build next, so it belongs at the front of the plan.
Free building energy assessment: common questions
What does the free energy assessment cost?
+
Nothing. The initial review is free, including when the answer is that a project does not make sense for the building.
What do I need to send?
+
Start with the property details. A utility bill is optional, but it lets us read the tariff and demand charges in the first review.
How long does it take?
+
A written initial review within 2 business days. A deeper assessment, if the property looks promising, takes longer and needs specific data we will name.
Is this the same as an ASHRAE energy audit?
+
No. It is an initial review of where the building's energy cost comes from and which projects are worth pursuing. A formal audit required by a local building performance law is a separate scope.
