See how EVOA works
A short look at what EVOA does, and what a free plan covers for your building.
Get my free planThe problem
Your property may be paying more each month than it needs to.
Most commercial properties have more than one way to cut the monthly bill. The hard part is finding them all, knowing which ones are worth it, and finding people you trust to do the work.
Everyone sells one piece
A solar company sells solar. An HVAC company sells HVAC. Nobody is paid to show you which mix could save your property the most.
Nobody looks at the whole building
Your roof, your site, your equipment and your bill all work together. Plan one system at a time and the savings may never add up the way they could.
You don't know who to trust
Different pitches, prices and promises are hard to compare, so it's easy to do nothing and keep paying.
We look at every way to save, together.
Your plan checks each of these against your building and your bill, then shows estimated cost, incentives and payback in one place.
Make your own power
Solar sized to your roof and your real usage.
Store it for later
Batteries that use your own power when rates are highest.
Tap the ground
Geothermal heating and cooling where your site allows it.
Heat and cool for less
HVAC options sized to your building's estimated needs.
Tighten the building
Envelope upgrades that can reduce the energy your property needs.
Charge EVs
EV charging, included only if you tell us you're interested.
How it works
From your energy bill to the partners who build it.
- 1
Tell us about your property
Your address and a recent energy bill, as a PDF or a phone photo. No bill handy? Your monthly cost works too. It takes about two minutes.
- 2
We size and design
We size each system internally, use specialized design software where it's needed, and combine the results into one free preliminary plan. For New York buildings it usually comes back within a day. Elsewhere our team builds it by hand.
- 3
Partners bid
Coming soon
Ready to move? Vetted partners in each trade bid on the same scope. Not ready? Keep the plan. No obligation.
- 4
Choose and build
Coming soon
Compare bids side by side and choose. The winning partner inspects the site, confirms the price, completes final design and builds the project.
Why start with EVOA
One plan, instead of a stack of sales pitches.
The usual way, you call a solar company, then an HVAC company, then someone about geothermal, and each one sells you their piece.
EVOA flips that. We start with your building and your bill, size every system together, and then connect you with partners to build it. Think of it as EnergySage for commercial buildings.
One plan for the whole building
Solar, batteries, geothermal, HVAC and envelope considered together, plus EV charging if you want it, with estimated cost and return in one place.
Free for owners, clear about how we earn
You never pay EVOA. Partners pay to be on the platform and pay a fee when they win work. They can't buy a higher ranking.
Vetted partners for each trade
Most projects need more than one company. We're building a network of vetted partners who can bid on the same scope, so offers are easier to compare.
Who it is for
Built for property owners and the partners who deliver the work.
