8-77 Definitions.

(a)    A "thermal energy system" shall mean any space condition, domestic hot water, cooking, appliance, process heat, or other building system that relies on thermal energy.

(b)    "Fossil fuel" shall include all fossil-based heating fuel, including coal, natural gas, kerosene, oil, and propane.

(c)    "Renewable energy" shall include all of the electrification, geothermal, and solar measures, and renewable fuels included in (d) and (e) of 30 V.S.A. § 8127. Renewable energy measures that do not rely on electrification, geothermal or solar will be subject to the applicable requirements of Section 8-78(a).

(d)    Any "renewable energy" fuel or measure set forth in subsection (c) of this section shall be considered excluded from the definition of "renewable energy" if the Vermont Public Utility Commission determines a renewable measure or fuel source is not eligible for renewable heat credits under the requirements of a State of Vermont Renewable Heat Standard or any similar State thermal energy policy.

(e)    A "large existing building" shall mean a building with at least fifty thousand (50,000) feet in total floor area of enclosed conditioned space, including hotels, but excepting the following:

(1)    All residential buildings; and

(2)    Buildings listed, or eligible to be listed, on the National Historic Register, provided the applicant can demonstrate to the satisfaction of the department of permitting and inspections that there is no renewable energy thermal energy system available to the building due to the historic nature of the building and any limitations imposed by the National Historic Register.

(f)    A "new building" shall mean the new construction of any building, excepting all additions, alterations, renovations, or repairs to an existing building.

(g)    An "existing city building" means all municipal buildings constructed prior to January 1, 2023, and owned by the City of Burlington, regardless of their size or square footage.

(Ord. of 6-28-21(1); Ord. of 11-20-23)

8-78 Renewable energy requirements.

(a)    New buildings. Applicants seeking permits pursuant to this chapter for new buildings shall demonstrate that the new building will utilize renewable energy thermal energy systems. If an applicant utilizes a primary thermal energy system that relies on renewable energy other than electrification, geothermal, or solar measures, the applicant must certify prior to receiving a permit that the use of electrification, geothermal, or solar measures is not technically feasible, is economically unduly burdensome, is not permitted by applicable regulation, or is not feasible for other similar reasons demonstrated to the satisfaction of the department of permitting and inspections. If an applicant utilizes a nonprimary thermal energy system that relies on renewable energy other than electrification, geothermal, or solar measures, the applicant must provide the department of permitting and inspection a written explanation of the reason for not using a thermal energy system that relies on electrification, geothermal, or solar measures.

(b)    Large existing buildings. Applicants seeking permits to replace space conditioning systems or domestic water heating systems that are in large existing buildings shall demonstrate the new space conditioning or domestic water heating systems will utilize renewable energy. This subsection (b) shall also apply to existing city buildings, except that existing city buildings are not subject to the carbon pollution impact fee established in Section 8-79.

(c)    Annual certification. If an applicant utilizes renewable energy in a thermal energy system capable of also using fossil fuels, the applicant must certify prior to receiving a permit and annually thereafter that the renewable energy fully offsets the annual usage for the thermal energy system. This certification may include, but shall not be limited to, submitting a contract, invoice, or proof of a subscription to or participation in a tariff program that demonstrates the applicant’s purchased renewable energy fully covers the annual need of the thermal energy system. If the applicant fails to provide annual certification for any thermal energy system capable of also using fossil fuels, that thermal energy system shall be considered a fossil fuel thermal energy system that may only be utilized pursuant to subsection (d) of this section, subject to the carbon pollution impact fee established in Section 8-79 prorated to the remaining lifetime of the fossil fuel thermal energy system.

(d)    Utilization of fossil fuel thermal energy systems. An applicant covered by this section may alternatively utilize a fossil fuel thermal energy system and the applicant’s building shall be subject to the carbon pollution impact fee established in Section 8-79, but no permit shall be issued to an applicant utilizing a fossil fuel thermal energy system unless the applicant establishes that the cost of a renewable energy thermal energy system is unduly burdensome. To establish that the cost of a renewable energy thermal energy system is unduly burdensome, the applicant must demonstrate to the satisfaction of the department of permitting and inspections that the twenty-five (25) year capital and operational cost of the least expensive renewable energy thermal energy system, including any available incentives, rebates, or tax credits, is more than the twenty-five (25) year capital and operational costs of the applicant’s fossil fuel thermal energy system and the carbon pollution impact fee that will be assessed on the applicant’s building.

(e)    Supporting incentives, rebates, or tax credits. Nothing in this article prevents or prohibits applicants from utilizing any and all available local, State, or federal incentives, rebates, or tax credits that support implementation of renewable energy for their buildings, and applicants are encouraged to access available incentives, rebates, or tax credits.

(Ord. of 6-28-21(1); Ord. of 11-20-23)

8-79 Carbon pollution impact fee.

(a)    Assessment of fee. Applicants utilizing a fossil fuel thermal energy system pursuant to Section 8-78(c) shall be assessed a carbon pollution impact fee on the greenhouse gas emissions from the applicant’s building or buildings that are attributable to the applied-for fossil fuel thermal energy systems. In no event should an applicant pay a carbon pollution impact fee twice for the same ton of carbon, and the department of permitting and inspections should ensure in application of the fee that it is not duplicative for applicants with multiple buildings or campuses.

(b)    Amount of fee. Effective January 1, 2024, the carbon pollution impact fee shall be equal to one hundred fifty dollars ($150.00) per ton of greenhouse gas emissions attributable to a building’s fossil fuel thermal energy systems over their lifetime, based on a net present value calculation (using a discount rate that is the lower of the rate used by either the environmental protection agency or the State of Vermont in calculating the social cost of carbon) at the time the permit application is submitted. The emissions attributable to a building’s fossil fuel thermal energy systems will be based on the expected lifetime of the system and its expected annual emissions. Applicants shall be required to submit this information during the permit process, and the department of permitting and inspections may work with Burlington electric department energy services staff to assess and verify applicant information for expected lifetime and emissions of a system in a building. On each subsequent January 1, the carbon pollution impact fee shall be increased by any percentage increase of the Consumer Price Index, CPI-U, U.S. city average, not seasonally adjusted, or successor index, as calculated by the U.S. Department of Labor or successor agency for the twelve (12) months preceding the previous September 1, but in no event shall the increase be greater than five (5) percent. The carbon pollution impact fee shall be rounded off to the nearest dollar.

(c)    Exceptions.

(1)    For large existing building applicants, the carbon pollution impact fee shall be capped at no more than seventy-five (75) percent of the installed cost of the proposed space conditioning or domestic water heating system.

(2)    An applicant building a new, residential multi-unit dwelling with four (4) or more units shall not be subject to the alternative compliance carbon pollution impact fee as it applies to domestic water heating systems until January 1, 2026.

(3)    If an applicant with one (1) or more buildings is seeking a permit pursuant to this chapter, and is already using one (1) or more thermal energy systems that rely on renewable energy, the applicant may apply for a credit toward any carbon pollution impact fee equal to the carbon value of the renewable energy used for any thermal energy system permitted by the City of Burlington since January 1, 2024, and not regulated under this article.

(d)    Renewable energy fund. All carbon pollution impact fee proceeds, except those funds needed to administer this article, shall be placed in a renewable energy fund established and managed by the department of permitting and inspections with technical support from the Burlington electric department. Renewable energy fund proceeds shall be made available as follows:

(1)    Half of the proceeds paid into the renewable energy fund by a large existing building applicant shall be available to the payor for projects to reduce greenhouse gas emissions at any site owned by the payor in the City of Burlington. The large existing building applicant must request these proceeds within one (1) year following payment of their carbon pollution impact fee; the applicant shall demonstrate to the satisfaction of the department of permitting and inspections that the proceeds will be used to meaningfully reduce greenhouse gas emissions; the proceeds may not be used to subsidize the cost of thermal energy sytems requlated by this article, and any proceeds not requested within that year shall be made available under subsection (d)(2) of this section.

(2)    Any remaining proceeds collected from large existing building applicants and all proceeds paid into the renewable energy fund by new construction applicants shall be available to provide financial assistance to help low-income Burlington residents with funding initiatives that reduce greenhouse gas emissions, including, but not limited to, the installation of renewable energy thermal energy systems, weatherization projects, or subsidizing utility costs associated with purchasing renewable energy rather than fossil fuel. This funding may be delivered either through direct payments to homeowners and renters who are income-qualified per the most recent income-qualification levels published by the community and economic development office ("CEDO"), or through payments to property owners of multifamily buildings where at least twenty-five (25) percent of the tenants in the building are income-qualified; provided, that the property owner must commit to not raising the rent of income-qualified tenants as a result of costs associated with the funded initiatives to reduce greenhouse gas emissions.

(Ord. of 6-28-21(1); Ord. of 11-20-23)

8-80 Effective date and reporting requirement.

(a)    The provisions of this article shall take effect on January 1, 2024.

(b)    The department of permitting and inspections shall maintain records on applications submitted pursuant to this article, including, but not limited to, information on applicant type, the size of an applicant’s building(s), the thermal energy system(s) applied for, whether the thermal energy system(s) utilize fossil fuel or renewable energy, and information submitted in support of an applicant utilizing fossil fuel or renewable energy. The department of permitting and inspections shall also maintain records on any carbon pollution impact fee proceeds paid into the renewable energy fund and how these proceeds have been distributed. The records required under this section shall be reported to the city council no later than January 1, 2026, and biannually thereafter, or otherwise upon request.
