Memorandum
REPORT TO:Sustainability Board
FROM:Jon Henderson, Strategic Services Director
SUBJECT:Electrification Campaign Work Session.
MEETING DATE:April 13, 2022
AGENDA ITEM TYPE:Citizen Advisory Board/Commission
RECOMMENDATION:Electrification Campaign Work Session.
STRATEGIC PLAN:6.3 Climate Action: Reduce community and municipal Greenhouse Gas
(GHG) emissions, increase the supply of clean and renewable energy; foster
related businesses.
BACKGROUND:
Action 1.A.3 of the Bozeman Climate Plan calls for energy efficiency
information and resources for private parties, Action 1.B.1 calls for high
performance building resources and training for the development
community, and Action 1.C.3 calls for outreach and incentives for high-
efficiency electric appliances and equipment. These are priority actions
needed to address energy efficiency of existing buildings (Solution A.), net
zero energy new construction (Solution B.), and building electrification
(Solution C).
The City of Bozeman has been recently accepted into Rocky Mountain
Institute’s 2022 Electrify Community Cohort. The goal for this effort is to
help communities launch Electrify campaigns to accelerate heat pump
adoption for space heating/cooling and water heating, particularly in
underserved neighborhoods. The City has partnered with the Montana
Weatherization Training Center to help reach a wide audience. This is a high
priority campaign with national, state, and community partnerships in place
to build an outreach and bulk purchasing campaign.
During our presentation, we will discuss the environmental and health
imperative of building electrification, why heat pumps are the preferred
solution, common barriers to electrification, and our anticipated community
engagement strategy. We would like the Board to consider the following
questions during the discussion:
What do you see as the local barriers to residential heat pump
adoption?
7
For new construction in Bozeman, how do we effectively provide
resources and trainings for the development community (architects,
designers, engineers, contractors, distributors, realtors etc.)?
For existing homes in Bozeman, how do we encourage homeowners
and landlords to consider heat pumps retrofits?
What can we do to make heat pumps more attainable for low-income
and median-income residents?
Useful background information can be found in Rocky Mountain Institute's
article "Building Electrification: A Key to a Safe Climate Future ", along with
the attached program map, and attached heat pump economic analysis.
UNRESOLVED ISSUES:None.
ALTERNATIVES:As suggested by the Sustainability Citizen Advisory Board.
FISCAL EFFECTS:$25,000 has been included in the City Manager's recommended FY23 budget
to support outreach and marketing materials.

RMI analyzed the costs of a new all-electric home versus a new mixed-fuel home that relies
on gas for cooking, space heating, and water heating. In Austin, the all-electric home saves
$4,400 in net present costs and 15 tons of CO2 emissions over a 15-year period.

Key Findings
The new all-electric home has a lower net present cost
than the new mixed-fuel home, with roughly equivalent
up-front costs and substantial annual bill savings.
• Up-front costs for the all-electric and mixed-fuel homes
are roughly equivalent. The Minneapolis climate requires
a higher capacity heat pump than other cities in the study.
This requirement comes at a higher cost, outweighing the
equipment and labor cost savings seen with heat pump
systems in milder climates.
• The all-electric home has 9% lower annual utility costs.
There are significant energy savings with heat pump space
and water heaters over corresponding gas appliances,
even though electricity costs more per unit energy than gas
in Minneapolis. The all-electric home also benefits from a
lower electricity rate during winter months.
• Carbon emissions from space heating, water heating, and
cooking are 51% lower in the all-electric home, due to more
efficient appliances and increasingly low-carbon electricity.

New Customer Gas Connection
We assume an out-of-pocket cost of $2,100 for the
gas connection of a new home, with scaling by a local
construction cost factor. This estimate is conservative,
as our research shows that the out-of-pocket cost range
for a new customer gas connection per lot is $0 to $15k+.
This cost varies widely depending on the extent of
infrastructure upgrade required and the ratepayer-funded
customer allowance from the utility in each location.

Methodology

•ASHRAE Standard 90.2-2019 used as reference HVAC

reflecting invoice analyses, contractor surveys, and
professional estimates. Costs were then scaled by
city using RSMeans Construction Cost Indices. HVAC
equipment costs were scaled on a per-ton basis

FROM:Jon Henderson, Strategic Services Director
SUBJECT:Bozeman Climate Plan Dashboard Work Session.
MEETING DATE:April 13, 2022
AGENDA ITEM TYPE:Citizen Advisory Board/Commission
RECOMMENDATION:Bozeman Climate Plan Dashboard Work Session.
STRATEGIC PLAN:6.3 Climate Action: Reduce community and municipal Greenhouse Gas
(GHG) emissions, increase the supply of clean and renewable energy; foster
related businesses.
BACKGROUND:Ongoing monitoring of progress and reporting of achievements is essential in
keeping the Climate Plan current and on track to achieve the City's climate
goals.
The City has recently invested in a technology platform that provides a
transparent view into recent accomplishments, current work, and future
initiatives related to specific action items listed in the Climate Plan.
Performance measures (i.e., charts and graphs) will be developed over time
to support a number of action items and solutions to help communicate
measurable progress.
The Bozeman Climate Plan Dashboard will be formally released to the public
through the City's website and presented to the City Commission on April 26,
2022 as part of the City's Climate Plan Triannual Report.
During our presentation, we will provide an overview of the dashboard. We
would like the Board to consider the following questions:
What do you like about dashboard, and how do you think the
dashboard can be used to keep the community informed over time?
What should the City consider as it relates to future enhancements to
make the dashboard more effective?
UNRESOLVED ISSUES:None.
ALTERNATIVES:As suggested by the Sustainability Advisory Board.
FISCAL EFFECTS:None.
