Find Your Electric Utility

Denver buildings often use a lot of energy for lighting, heating, cooling, and hot water. Many buildings were built before modern energy codes, so upgrades can lower monthly bills.

Energy Help in Denver

Energy Audits

An energy audit is a walk through of your building by someone who looks at how energy is used. They check lighting, heating, cooling, hot water, and how long equipment runs.

You get a list of upgrades and a rough idea of what each one saves. Some utility programs pay part of the cost of a study for larger buildings. Ask your utility what is offered this year.

Financing

Many buildings pay for upgrades in one of three ways: cash, equipment financing through a lender, or a longer term program like Colorado C-PACE.

Rebates lower the amount you need to finance. Utility rebates are usually paid after the work is done and approved, so plan for that timing.

Colorado C-PACE

Colorado C-PACE is a state program that lets owners of eligible commercial buildings pay for energy improvements over a long term, repaid through a voluntary assessment on the property.

It is often used for larger projects that mix lighting, heating, cooling, and building shell work. Terms and eligibility are set by the program, so review the official program site before you plan around it.

Find a Commercial Energy Professional

We are not a contractor and we do not install equipment. When you are ready, we can point you to a commercial energy professional who works on buildings like yours.

Before you sign anything, ask for a written scope, the fixture or equipment list, the rebate paperwork plan, and who files the rebate application.

Colorado C-PACE can help pay for larger energy projects over time. Some utilities and lenders also offer financing. Terms depend on the building and the lender.
