Ordinance entitled “Building Energy Use,” Chapter 8.67 of the Municipal Code of the City of Cambridge Building Energy Use Disclosure and Emission Reductions BEUDO (Ordinance 2021-26)

“Alternative Compliance Credit” shall mean a credit obtained by a Covered Property Owner to offset greenhouse gas emissions from the Covered Property. One Alternative Compliance Credit shall be equivalent to one metric ton of Greenhouse Gas Emissions. In the first Compliance Period, each Alternative Compliance Credit shall cost $234.

The Assistant City Manager for Community Development shall promulgate regulations pursuant to 8.67.130 prior to each Compliance Period to establish the price of the Alternative Compliance Credit for that Compliance Period, based on review of the average cost of reducing one metric ton of greenhouse gas emissions in Covered Properties.

Monies from Alternative Compliance Credits shall be used by the City solely for City programs and projects that directly reduce carbon emissions, including but not limited to, greenhouse gas reduction projects in Affordable Housing properties, if approved by the Cambridge Affordable Housing Trust.

“Approved Verification Body” shall mean a firm accredited by the American National Standards Institute to conduct greenhouse gas inventory verification services.

“Baseline” shall mean the average of Greenhouse Gas Emissions of Covered Properties for two consecutive calendar years comprising the default baseline, alternative baseline, or new covered properties baseline as set forth in section 8.67.100 for purposes of calculating emissions reduction targets in order to meet the requirements of this ordinance set forth in section 8.67.100.

“Benchmarking Information” shall mean information input and/or generated by the Benchmarking 2

Tool, as herein defined including descriptive information about the physical property and its operational characteristics. The information shall include, but need not be limited to:

Property address; Primary use type; Gross floor area; Site Energy Use Intensity (EUI) as defined in this section; Weather normalized Source EUI; (f) Annual greenhouse gas emissions; (g) Water use; and (h) The energy performance score that compares the energy use of the building to that of similar buildings, where available.

“Benchmarking Tool” shall mean the ENERGY STAR Portfolio Manager tool developed and maintained by the U.S. Environmental Protection Agency to track and assess the relative energy performance of buildings nationwide, and/or other tools identified by the Department to collect and track Benchmarking Information necessary for compliance with this ordinance.

“Campus” shall mean a minimum of 5 (five) Covered Properties owned by the same Owner, or any number of Affordable Housing properties owned by the same Owner.

(8) “Compliance Period” is a defined set of years, in each year of which Covered Properties must achieve the performance requirements of 8.67.100. Compliance Period 1 is the years 2026 through 2029. Compliance Period 2 is the years 2030 through 2034. Compliance Period 3 is the years 2035 through 2039. Compliance Period 4 is the years 2040 through 2044. Compliance Period 5 is the years 2045 through 2049. Compliance Period 6 is the years 2050 and onwards.

(9) “Condominium” shall mean a residential or non-residential condominium property established pursuant to G.L. c 183A, as may be identified by the City of Cambridge Assessor’s Records.

(10) “Cooperative” shall mean a multi-dwelling complex in which owners acquire an interest in the entire complex and a proprietary lease to their own apartment or dwelling, which complex is formed or held pursuant to Chapters 156C, 156D, 157, 157B, or 180 or similar provision in the Massachusetts General Laws.

(11) “Covered Property” shall mean a parcel, as described in public records or as determined by the Department, containing any of the following:

One or more non-residential building(s) where such building(s) singly or together contain 25,000 or more Covered Square Feet One or more residential building(s) that singly or together contain 50 or more residential Dwelling Units

(12) “Covered Square Feet” shall mean the living area of the property as per the City of 3

Cambridge Assessors’ records.

(13) “Department” shall mean the City of Cambridge Community Development Department.

(14) “Dwelling Unit” shall mean a single residential unit, as defined by the Cambridge Zoning Ordinance, consisting of one or more habitable rooms, occupied or arranged to be occupied as a residential unit separate from all other residential units within a building, and used primarily for residential purposes and not primarily for professional or commercial purposes.

(15) “Emission Factors” shall mean the multipliers used to determine the annual Greenhouse Gas Emissions produced by the production or consumption of Energy. The Assistant City Manager for Community Development shall promulgate regulations pursuant to 8.67.130 no later than the year prior to each Compliance Period to establish the annual Emission Factors for that Compliance Period, and no later than one year prior to the first Compliance Period to establish the annual Emission Factors for 2010-2025.

For the combustion of fuels, such as oil and gas, the Emission Factors will be based on standard scientific values published by federal agencies. For the use of all electricity purchased from the grid other than Renewable Electricity, the annual Emission Factor will generally reflect the emissions intensity of electricity consumed in Massachusetts.

For the generation of steam, hot water, and chilled water, and the generation of electricity other than Renewable Electricity, the Emission Factor for each output from the generation facility will be calculated using the Greenhouse Gas Protocol methodology jointly developed by the World Resources Institute and World Business Council for Sustainable Development, or similar methodology, using data provided by the generation facility owner.

(16) “Energy” shall mean purchased electricity, natural gas, steam, hot or chilled water, heating oil, or other product or electricity generated on site, for use in a building for purposes of providing heating, cooling, lighting, water heating, or for powering or fueling other end-uses in the building and related facilities, excluding any verified amount of electricity used for charging electric vehicles.

(17) “ENERGY STAR Portfolio Manager” shall mean the tool developed and maintained by the U.S. Environmental Protection Agency to track and assess the relative energy performance of buildings nationwide.

(18) “Energy Use Intensity (EUI)” shall mean a building’s annual energy consumption measured in kBTUs (1,000 British Thermal Units) used per square foot of gross floor area.

(19) “Greenhouse Gas Emissions” (GHG) shall mean the carbon dioxide equivalent emissions produced from the operations of the Covered Property calculated by the Department according to the following calculation:
