Summary

Boulder's green building rules live in its own Energy Conservation Code at BRC 10-7-2, which adopts the 2024 City of Boulder Energy Conservation Code (CoBECC), amended for local conditions. New construction must include electric vehicle charging under amended Section C405.13, and projects seeking HVAC efficiency credits under C406.2.2 must meet specific SEER, EER, and AFUE benchmarks referenced by the code's tables.

10-7-2. - Energy Conservation Code. (a)Council adopts by reference the 2024 City of Boulder Energy Conservation Code published by the International Code Council which shall have the same force and effect as though fully set forth in the Boulder Revised Code, 1981, except as specifically amended by the provisions of this chapter. This code shall also be known as the City of Boulder Energy Conservation Code. This chapter and the 2024 City of Boulder Energy Conservation Code shall be administered, applied, and interpreted in accordance with and as part of Chapter 10-5, "Building Code," B.R.C. 1981.(b)Section C405.13, "Electric vehicle (EV) charging for new construction," is repealed and reenacted to read as follows: C405.13 Electric vehicle (EV) charging for new construction. The building shall be provided with electric vehicle (EV) charging in accordance with this section and the National Electrical Code (NFPA 70). Where parking spaces are added or modified without an increase in building size, only the new parking spaces are subject to this requirement.

Full Breakdown

BRC 10-7-1 sets out the purpose behind Boulder's separate energy chapter: conserving scarce energy resources by regulating building construction standards to minimize energy consumption for heating, cooling, lighting, and ventilating structures, while encouraging green building techniques. Section 10-7-2(a) adopts by reference the 2024 City of Boulder Energy Conservation Code published by the International Code Council, giving it the same force as if written directly into the Boulder Revised Code, and folds its administration into Chapter 10-5, the Building Code. The chapter then layers city-specific amendments on top of the base code.

13, 'Electric vehicle (EV) charging for new construction,' as repealed and reenacted by 10-7-2(b), requires new buildings to provide EV charging in accordance with the section and the National Electrical Code, with the number of required EVSE-installed, EV-ready, EV-capable, and EV-capable-light spaces determined by the total count of provided motor vehicle parking spaces; where parking is added or modified without increasing building size, only the new spaces trigger the requirement. 3, with oversized equipment held to the efficiency listed for the largest table capacity and multi-system projects averaged by weighted capacity. The city manager can adopt reasonable interpretive and administrative rules under 10-7-3 to help applicants show compliance.

Violations & Fines

Building without meeting the adopted Energy Conservation Code, including skipping the required EV charging infrastructure under C405.13 or claiming HVAC efficiency credits without meeting the referenced performance tables, is enforced through the same Building Code violation framework incorporated by Chapter 10-5: civil penalties starting at $150 for a first offense and climbing to $1,000 for a third, plus the possibility that occupancy approval is withheld until the energy code deficiencies are corrected.

Frequently Asked Questions

Does Boulder require EV charging in new buildings?
Yes. Section C405.13 of the adopted Energy Conservation Code, reenacted at BRC 10-7-2(b), requires new buildings to provide electric vehicle charging that complies with the section and the National Electrical Code. The number of EVSE-installed, EV-ready, and EV-capable spaces required is calculated from the total number of vehicle parking spaces the project provides, and additions that don't grow the building only trigger the rule for the new spaces.
What energy code edition does Boulder currently use?
The 2024 City of Boulder Energy Conservation Code (CoBECC), adopted by reference at BRC 10-7-2(a) and administered together with Chapter 10-5, the Building Code. It's a locally amended version of the International Code Council's energy code rather than an unmodified state or national standard.
How do I get HVAC efficiency credits under Boulder's energy code?
Under amended Section C406.2.2, your heating and cooling systems first have to meet the baseline requirements of Section C403, then reference the seasonal or part-load efficiency numbers, SEER/SEER2, EER, IEER, IPLV, or AFUE, in the tables tied to Section C403.3.3. Oversized equipment is measured against the efficiency listed for the largest table capacity, and projects with multiple systems use a capacity-weighted average.
