Lighting Upgrades
IMPORTANT CHANGES TO 2021 BPO DEADLINES
The City of Boulder is officially extending the 2021 compliance deadlines associated with the Boulder Building Performance Ordinance (Ordinance No. 8071) in order to minimize near-term impacts as area businesses continue to recover from the economic impacts of COVID-19. Specific deadlines that are to be extended are:
- Energy Assessment requirement for all buildings 30,000 to 49,999 square feet extended from June 1, 2021 to Dec. 31, 2021;
- The One-time Lighting Upgrade requirement for all buildings 50,000 and greater (including city facilities) extended from June 1, 2021 to June 1, 2022; and,
- Retro-commissioning Report requirements for all buildings over 50,000 square feet and larger (including city facilities) extended from June 1, 2021 to June 1, 2022. All Retro-commissioning Measure Implementation requirements will be moved from June 1, 2023 to June 1, 2024.
There will be no change to June 1, 2021 Rating and Reporting deadline for all buildings 20,000 square feet and larger including city facilities.
Overview
Affected building owners must complete one-time lighting upgrades that meet specific energy codes for interior and exterior lighting power, controls and sensors as outlined below.
| Lighting Requirement | Code | Code Section |
| Occupancy Sensor Controls | 2017 COBECC | C405.2.2.2 |
| Time-switch Controls | 2017 COBECC | C405.2.2.1 |
| Exterior Lighting Controls | 2017 COBECC | C405.2.4 |
| Interior Lighting - Power | 2017 COBECC | C405.5 |
| Exterior Lighting - Power | 2012 IECC | C405.6 |
2012 IECC= 2012 International Energy Conservation Code
2017 COBECC = 2017 City of Boulder Energy Conservation Code 
- Review the Lighting Compliance Checklist to prepare for compliance.
- For interior lighting compliance, you are REQUIRED to complete and submit the Interior Lighting Compliance Form
. For exterior lighting compliance, submit a copy of your 2012 IECC ComCheck Compliance Certification. - Submit your lighting compliance through this Submission Form . More information on required documentation can be found in the Efficiency Requirements How-to Guide .
Electrical Permit
If lighting upgrades are necessary to meet compliance, an electrical permit may be required. To ensure your lighting project is reviewed against the BPO lighting requirement (and not the entire City of Boulder code), ensure you submit the Building Performance Ordinance Checklist and Electrical Permit together to Planning & Development Services .
Cost Saving Opportunities
Lighting rebates may be available through Xcel Energy and Boulder County PACE . Connect with a PACE Business Sustainability Advisor at Boulder County to identify applicable rebates. Call 303-786-7223 or email [email protected]
BPO and the Outdoor Lighting Ordinance
Building owners are encouraged to ensure any lighting upgrades completed for the Building Performance Ordinance on the exterior of the building also meet the Outdoor Lighting Ordinance requirements. The Outdoor Lighting Ordinance of 9-9-16 B.R.C. 1981, includes specific lighting standards that apply to all new development and newly proposed exterior lighting. Additionally, 9-9-16 also contains thresholds for incremental compliance (based on cumulative project valuation compared to existing structure valuation) that must be addressed at the time of building permit application for work that triggers such lighting improvements. Lastly, the Outdoor Lighting Ordinance includes an amortization deadline requiring compliance of all exterior lighting by Nov. 2018.
The BPO lighting deadlines begin in 2021 based on building size. However, with the Outdoor Lighting Ordinance amortization deadline in Nov. of 2018, owners are encouraged to comply with both ordinance lighting requirements at the same time to capture economies of scale and realize cost savings for the exterior lighting upgrades required by both ordinances.
Lighting Compliance Overview
Proving Compliance
There are several steps to complying with the one-time BPO Lighting Compliance requirement:
- Determining if your Exterior Lighting Controls are Compliant with the 2017 City of Boulder Energy Conservation Code (COBECC).
- Determining if your Exterior Lighting Power is Compliant with 2012 International Energy Conservation Code (IECC)
- Determining if Interior Lighting Power is Compliant with the 2017 City of Boulder Energy Conservation Code
- Determining if your Interior Time Switch and Occupancy Sensor Controls are Compliant with the 2017 City of Boulder Energy Conservation Code
To show compliance in each of the 4 areas outlined above, you must work with a qualified lighting contractor or PE to submit the appropriate documentation. The Table below illustrates the required submittals.
| Compliance Submittal Guidance Chart | |||
| Fully Upgraded and Permitted Lighting Already in Place (with a permit issued after March 1, 2017) | Permit Unavailable or No Upgrade Necessary (already in compliance) | Partially Upgraded or Unsure | |
| Outdoor Lighting | |||
| Power | COMCheck Certification* | COMCheck Certification* | COMCheck Certification* |
| Controls | Indicate controls scheme on Lighting Submission Form | Indicate controls scheme on Lighting Submission Form | Indicate controls scheme on Lighting Submission Form |

How do I find the right Lighting Contractor to perform this work?
The work can be performed by any qualified individual either internal or external to the organization; however, verification that the work meets the requirements must be certified by someone carrying professional engineering license issued by the State of Colorado or a . When considering hiring a contractor to perform this work, the following qualifications should be considered:
- Have a staff member with one of the following certifications: CLEP (Certified Lighting Energy Professional, PE or LC (Lighting Consultant) (alternative certifications will be approved on a case-by-case basis)
- Have at least 5 years of experience performing lighting audits and upgrades
- Have specific experience with LED lighting and controls
- Have an understanding of and experience in the 2017 City of Boulder Energy Conservation Code, the 2012 International Energy Conservation Code and COMCheck
- Have completed at least 5 interior and/or exterior lighting projects since the inception of the 2017 City of Boulder Energy Conservation Code
The City of Boulder has posted a list of pre-screened lighting contractors that meet the above qualifications.
What is a Lighting Audit?
A lighting audit is a room-by-room assessment of the types, voltage/wattage, and functionality of lighting fixtures and controls that currently exist in your building.
Although we do not have a REQUIRED format for the lighting audit submittal, we would highly advise you to work with your contractor to insure that, at a minimum, your audit includes:
- power density calculations (using our Interior Lighting
- Compliance Form or ComCheck for Exterior Lighting)
- drawings
- fixture counts
- light readings
- If your building is NOT in compliance, the audit should include a turnkey solution that includes: a detailed room by room solution list, photometric drawings, energy savings with rebates, project timeline and cost of installation.
This seems like it could get expensive. Is there any information or support around some of the costs of auditing and/or upgrading lighting?
Lighting upgrades are not only some of the best investments with the fastest paybacks for building owners; but they offer the ongoing longer-term benefits of lower utility bills, better quality lighting and reduced maintenance costs! Payback periods can be made even faster with the addition of rebates from your local utility provider and other municipal rebate opportunities.
There are a variety of methods available to you, the building owner, to support the costs of performing lighting audits and any required upgrades.
Rebates are currently available through Xcel Energy to defray the cost of your project. You may also receive support through Boulder County’s Partners for a Clean Environment (PACE).
Stand-alone lighting audits typically cost $0.02-$0.06 per square foot depending on the complexity of the facility. This may be offered at no cost when your contractor is also performing the lighting upgrade.
Once your contractor has determined that your building will need lighting upgrades to meet compliance requirements, your audit SHOULD include a list of potential rebates available to you to lower the cost of your equipment purchases. Often, lighting contractors will submit rebate applications on your behalf to lower the total contracted cost of your upgrades.
If you own several buildings within the City of Boulder, you may consider asking your lighting contractor for a set cost per square foot for the entire portfolio to perform lighting audits.
Some lighting contractors offer financing mechanisms, such as performance contracting, paying for Lighting as a Service or financing through a contractor/bank arrangement.
