    Using BuiltCold is optional. The Colorado Energy Office funded the platform; this page is BuiltCold's and does not speak for the state. The Office of the State Architect sets eligibility. Estimates are illustrative.

    Build cleaner. Skip the sales tax.

    Colorado exempts lower-carbon materials from the 2.9% state sales and use tax. BuiltCold supports project teams with enrollment, documentation and submittals.
