Which type of provider do you need?
For an existing office, warehouse, retail property, multifamily building, hotel, or industrial facility, I'd generally divide the market this way:
Need
Provider type
Determine what the building needs
Energy/engineering consultant
Design the retrofit
MEP/energy engineering firm
Replace HVAC and controls
Building systems integrator such as Trane or Johnson Controls
Add solar/storage
Renewable-energy EPC/developer
Actually construct the retrofit
General contractor / design-build firm
Finance the improvements through energy savings
Important: "Net-zero" can mean different things. A building can be highly energy efficient, net-zero carbon, or net-zero energy (annual energy consumption offset by renewable generation). For an existing commercial building, getting to genuine net-zero energy often requires combining deep efficiency measures with electrification and on-site or contracted renewable energy rather than simply installing solar.
If you're looking for providers that will actually take an existing commercial building from its current condition through design, construction, financing, and verification of net-zero performance, I can narrow this to 10–15 U.S. firms and compare their capabilities, typical building sizes, financing models, and geographic coverage.
