SUBJECT:Planned Development Zone Sustainable/Resilient Design Administrative
Manual
MEETING DATE:May 10, 2023
AGENDA ITEM TYPE:Citizen Advisory Board/Commission
RECOMMENDATION:Receive presentation, discuss questions, and provide input on guiding
questions.
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:
On July 13, 2022, the Sustainability Citizen Advisory Board held a Work
Session on the proposed Planned Development Zone process intended to
encourage efficiency and innovation in the built environment that reduces
the use of non-renewable energy for public benefit through efficient
electrification, energy efficiency, onsite renewable energy, and electric
vehicle charging stations.
Specifically, the Sustainable/Resilient Design PDZ requires that “the general
development plan or other documentation acceptable to the review authority
ensures that the level of combined water consumption, non-renewable
energy consumption, average daily motor vehicle trip generation, or a
combination thereof from all structures and uses included in the PDZ shall be
at least 25 percent lower than levels commonly experienced by development
meeting current established standards in each of the reference base districts
listed in the PDZ.”
On September 13, 2022, the City Commission provisionally adopted
Ordinance 2014 to repeal and replace Division 38.430 Planned Unit
Development with a new Planned Development Zone process in an effort to
support affordable housing, historic preservation, and sustainability. The
final adoption was completed with a second reading on September 27, 2022.
7
On September 14, 2022, staff provided an update to the Sustainability Board
on how comments from the Board were incorporated into the City's draft
implementation plan. Natalie Meyer, Sustainability Program Manager, will
present the board with an overview of the Sustainable/Resilient design
manuals, with a focus on the non-renewable energy manual and the
relationship of the provisions to federal incentives available through the
Inflation Reduction Act.
Guiding Questions:
The Planned Development Zone primarily serves as an incentive for larger-
scale new developments to provide a public benefit as defined under
Ordinance 2014.
What type of targeted outreach should we pursue to encourage the use of
the PDZ Sustainable/Resilient Design provisions?
Are there complementary education and outreach programs we should
consider to encourage participation?
UNRESOLVED ISSUES:None.
ALTERNATIVES:As identified by the Board.
FISCAL EFFECTS:None.

Sustainable/Resilient Design PDZ, Reduction in Non-Renewable Energy
Administrative Procedures Manual
I. Purpose
It is the intent of the City through the use of the Planned Development Zoning (PDZ) to encourage
efficiency and innovation in the built environment that reduces the use of non-renewable energy for
public benefit through energy efficiency and on-site renewable energy. A 25% reduction in non-
renewable energy may be achieved through one or a combination of the following categories:
1. Commercial Buildings
i. Energy Efficiency
ii. On-site Renewable Energy
2. Residential Buildings
i. Energy Efficiency
ii. On-site Renewable Energy
II. Authority
Sec. 38.200.010, BMC recognizes that the City Commission has the authority to review and require
revisions to all planned development zones. Sec. 38.430.130 authorizes the City Manager to establish
administrative procedures to implement planned development zones.
III. Definitions
“Climate zone” means a geographical region based on climatic criteria as specified in the 2021
International Energy Conservation Code.
“Commercial building” means all buildings that are not included in the definition of “residential
building”.
“Energy analysis” means a method for estimating the annual energy use of the proposed design and
standard reference design based on estimates of energy use.
“Energy Rating Index (ERI)” means a performance path that gives the option of complying with the 2021
IECC by meeting a target ERI score through a wide range of performance options with some mandatory
code requirements. The ERI score is a numerical score where 100 is equivalent to the 2006 IECC and 0 is
equivalent to a net-zero energy home. Each integer value on the scale represents a 1% change in the
total energy use of the rated design relative to the total energy of the ERI reference design.
“Energy simulation tool” means an approved software program or calculation-based methodology that
projects the annual energy use of a building.
“Energy Utilization Intensity (EUI)” means the site energy for either the baseline building or the
proposed building divided by the gross conditioned floor area plus any semi-heated floor area of the
building. For the baseline building, the EUI can be divided between regulated energy use and
unregulated energy use.
9

“Home Certification Organizations (HCOs) are independent organizations recognized by the
Environmental Protection Agency to implement an Energy Star certification program based on the
Energy Star Residential New Construction program requirements for site-built single-family and
multifamily homes and apartments when an Energy Rating Index (ERI) is used. Energy Rating Companies
(e.g. rater companies and providers) providing third-party verification for these compliance paths are
required to operate under an HCO.
“IECC” means the 2021 International Energy Conservation Code, published by the International Code
Council, Inc.
“Non-renewable energy” means fossil energy sources, including but not limited to oil, propane, coal, and
natural gas.
“On-site renewable energy system” means a renewable energy system located within the Planned
Development Zone.
“Proposed design” means a description of the proposed building used to estimate annual energy use for
determining compliance based on total building performance.
“Qualified Individual” is an individual not related to the Owner who is an engineer or contractor licensed
in the State of Montana. The qualified individual must demonstrate in writing to the owner that
he/she/they has the requisite qualifications to provide the certification or to perform the inspection and
testing required for the certification.
“Renewable energy system” means photovoltaic, solar thermal, geothermal energy, and wind systems
used to generate energy.
“Residential building” means a building containing dwellings and subject to the International Residential
Code or International Building Code as applicable.
“Standard reference design” means a version of the proposed design that meets the minimum
requirements of the code and is used to determine the maximum annual energy use requirement for
compliance based on total building performance.
IV. Application Process
A PUD application must follow the application process outlined in the Planned Development Zoning
(PDZ). In order to qualify for a PDZ with an emphasis on Sustainability, Non-Renewable Energy, the
development must be reviewed against the development standards established in the UDC and all
applicable building codes adopted by the State of Montana and the City of Bozeman Building Division.
It is recommended that prior to the pre-application review, the applicant meet with the City of
Bozeman’s Sustainability Division and Building Division. City staff will review applications on a case-by-
case basis when determining whether the required standards are adequate to move to formal review by
the City Commission.
V. Non-Renewable Energy Sustainable/Resilient Design Projects
Energy Efficiency and Renewable Energy Standard: Commercial Buildings
For the purposes of implementing Sec. 38.430.050.C, BMC, the non-renewable energy criteria for
commercial buildings may be achieved by certifying that the installation of the building envelope; the
10
3
heating, cooling, ventilation, and hot-water systems; and/or the interior lighting systems; and/or on-site
renewable energy systems, of the proposed design will reduce the total annual energy and power use by
25% in comparison to a reference design building.
Computer modeling must be used to compare two virtual buildings. The first virtual building is the
reference building. The reference building is identical to the proposed building except that the interior
lighting systems; heating, cooling, ventilation, hot water systems; and building envelope meet only the
minimum requirements as set by the most recent American Society of Heating, Refrigerating, and Air
Conditioning Engineers (ASHRAE) Standard 90.1. affirmed no later than the date that is 2 years before
the date that construction of the project begins, or the date the construction permit of the proposed
building. If the computer modeling indicates that the proposed building’s total annual energy and power
costs are less than the reference building’s total annual energy and power use by 25% or more, the
project is eligible for the Non-Renewable Energy Sustainable/Resilient Design.
Where multiple building types are identified within the PDZ, models should be created to demonstrate
the target percent reduction for each building type. Where the applicant proposes a combination of
more than two public benefits within the Sustainable/Resilient Design criteria, or other categories
eligible under the PDZ, the applicant may propose a percentage reduction that is less than 25%.
Commercial Building Submittal Materials
The non-renewable energy criteria for commercial buildings require four submittal phases:
1) PDZ Application – Identify intended methods to meet 25% reduction target and written
commitment to complete
2) Zoning or subdivision entitlement application – identify intended methods to meet 25%
reduction target, expected size of building(s) in sq. ft., location and type of intended on-site
renewable energy system if any, and written commitment to complete
3) Building design submittal - identify intended method to meet 25% reduction target, provide
modeling and energy analysis, identified construction methods, and written commitment to
complete
4) Post-installation verification and certification
Application
A completed PDZ application is outlined in Sec. 38.220.120, BMC. In addition, specific to the
Sustainability/Non-renewable Energy option the application must include a detailed narrative of the
anticipated energy modeling, energy conservation measures, and renewable energy systems that will be
included in the building design and construction. The target energy reduction for each building will be
identified within the application materials. The application also needs to mention how the measures
advance the Bozeman Community Plan (2020) and as updated.
Building Design Submittal1:
1) Square footage of the building(s).
2) Architectural documents used to determine the square footage of the building.
1 Submittal requirements are intended to align with the Internal Revenue Service 179D Energy Efficient
Commercial Buildings Deduction. Applicants claiming the IRS 179D deduction are advised to independently verify
all current eligibility and submittal requirements. Renewable energy systems are not eligible under IRS 179D but
may be eligible under Section 48 Investment Tax Credit.

3) Anticipated date of occupancy.
4) Computer modeling – energy model input and output files for proposed and reference buildings.
For a list of approved modeling software, visit the Qualified Software for Calculating Commercial
Building Tax Deductions.
a. The energy analysis will minimally include all assumptions around building occupancy, hours
of operation, and temperature settings.
5) Technical specifications and drawings required by the designer of the project.
6) The amount of reduction in total annual energy and power costs for each building type. Energy
efficiency and on-site renewable energy reductions must be identified as separate reductions.
7) The annual production of an on-site renewable energy system may be estimated using PV Watts
or an approved energy simulation tool. The submittal will include the percentage of the
building’s energy consumption to be provided by an on-site renewable energy system.
a. Sample system details for solar photovoltaics (PV):
i. DC System Size (kW) and System Output (kWh/year)
ii. Approximate Nominal Efficiency
iii. Array Type (fixed, tracking, two-axis tracking)
iv. Tilt angle (deg)
v. Azimuth angle (deg)
b. Sample calculation:
i. A proposed 50,000 ft2 building with a modeled Energy Use Intensity of 52
kBtu/ ft2 /year and a 50kW PV system with a generating output of 62,274
kWh/year would calculate the percent reduction in non-renewable energy as:
• 62,274 kWh/year = 212,529 kBtu/year
• 212,529 / 50,000 ft2 = 4.3 kBtu/ ft2 /year
• 52 – 4.3 = 47.8 kBtu/ ft2 /year
• ((52 – 47.8) / 52) x 100 = 8.2%
• 8.2% = reduction in non-renewable energy from an on-site
renewable energy system

9) Penalty of Perjury Statement
a. A declaration, applicable to the certification and any accompanying documents, signed by
the qualified individual, in the following form:
“Under penalties of perjury, I declare that I have examined this certification, including
accompanying documents, and to the best of my knowledge and belief, the facts presented
in support of this certification are true, correct, and complete.”
Energy Efficiency and Renewable Energy Standard: Residential Buildings
For the purposes of implementing Sec. 38.430.050.C, BMC, the non-renewable energy criteria for
residential buildings may be achieved by applying the 2021 IECC Energy Rating Index (ERI) Compliance
Alternative or the Department of Energy (DOE) Zero Energy Ready Home Program2.
Under these options, the standard reference design for single-family residential buildings is a maximum
Energy Rating Index of 54, without an on-site renewable energy system, in Bozeman’s Climate Zone 6.
Each ERI point reduction is recognized as a 1% reduction in non-renewable energy with the certification
of an approved third-party inspector or rater. For reference, Appendix RC, Zero Energy Residential
Building Provisions in the 2021 IECC identifies an ERI of 46 in Climate Zone 6 as the minimum level of
efficiency, without an on-site renewable energy system, needed to achieve Zero Energy ready
residential construction.
Applicants pursuing the DOE Zero Energy Ready Home program may identify a custom ERI target based
on the applicable single household or multihousehold program requirements with the certification of an
approved third-party inspector or rater. Where multiple building types are identified within the PDZ,
models should be created to demonstrate the target percent reduction for each building type. Where
the applicant proposes a combination of more than two public benefits within the Sustainable/Resilient
Design criteria, or other categories eligible under the PDZ, the applicant may propose a percentage
reduction that is less than 25%.
2 Applicants are responsible for identifying the appropriate version of the Zero Energy Ready Home Certification
program to be eligible for the New Energy Efficient Home Tax Credit found in section 45L of the Internal Revenue
Code.

Residential Building Submittal Materials
The Sustainability/Non-renewable Energy option for residential buildings requires three submittal
phases:
1) PDZ Application – Identify intended methods to meet 25% reduction target and written
commitment to complete
2) Zoning or subdivision entitlement application – identify intended methods to meet 25%
reduction target, type of proposed homes, location and type of intended on-site renewable
energy system if any, and written commitment to complete
3) Building design submittal - identify intended method to meet 25% reduction target, provide
modeling and energy analysis, identified construction methods, and written commitment to
complete
4) Post-installation verification and certification
Application
A completed PDZ application is outlined in Sec. 38.220.120, BMC. In addition, specific to the
Sustainability/Non-renewable Energy option include a narrative of the anticipated residential building
energy efficiency measures and any on-site renewable energy systems that will be included in the
building design and construction. The application will specify that verification of compliance will be
completed by an approved third-party inspection agency in accordance with Section R105.4. and/or a
Zero Energy Ready Home Program approved rater or another qualified third party operating under a
Home Certification Organization (HCO). The target energy reduction for each building will be identified
within the application materials. The application also needs to describe how the measures advance the
Bozeman Community Plan (2020) and as updated.
Building Design Submittal
1) The application must specify a compliance path through Section R406 Energy Rating Index
Compliance Alternative and/or the Zero Energy Ready Home Program.
2) Identify an approved third-party inspection agency in accordance with IECC Section R105.4 and,
if applicable, an approved verifier for third-party inspections under the DOE Zero Energy Ready
Home National Program Requirements. This party must be a rater that is working under the
oversight of an EPA-recognized Home Certification Organization (HCO).
3) Compliance based on the Energy Rating Index Compliance Alternative must conform to the
criteria established in the 2021 IECC Section R406.1 through R406.7.6, including R406.3.2 where
on-site renewable energy systems may be included.
4) Compliance based on the DOE Zero Energy Ready Home National Program Requirements
requires the following documentation:
a. The ERI of the DOE Zero Energy Ready Home “Target Home” for single household or
“Dwelling Design” for multihousehold
b. The size modification factor.
c. Complete ERI software calculations for a preferred set of energy measures and verify
resulting ERI at or below DOE Zero Energy Ready Home “Target Home” for single household
or “Dwelling Design” for multihousehold ERI, modified, as required, for house size.
d. A narrative describing the on-site renewable energy system with the installed capacity (kW)
annual energy production (kWh/year) of the proposed design using PV Watts or an
approved energy simulation tool. Submit the adjusted ERI based on the annual energy
production of the renewable energy system. The energy analysis will be provided by an
14
7
approved third-party rater. Each ERI point reduction from on-site renewable energy systems
is recognized as a 1% reduction in non-renewable energy use.3
e. Verification that all requirements have been met using an approved “verifier”, referring to
the person completing the third-party inspections required for qualification. This party must
be a rater that is working under the oversight of an EPA-recognized Home Certification
Organization (HCO).
f. Identify the target percent reduction of non-renewable energy. Both pathways for
residential compliance will use an ERI of 54 as the standard reference design from the 2021
IECC Table R406.5 Maximum Energy Rating Index, then subtract the percent reduction of
the proposed design, and repeat the calculation for each residential building type within the
PDZ.
i. Sample calculation:
• A standard reference design ERI of 54
• 54 – 10% = 44 ERI
• An ERI proposed design of 44 represents a 10% reduction of non-renewable
energy
Post-installation Verification
Prior to receiving a Certificate of Occupancy (CoO), the applicant will submit compliance verification that
all residential buildings within the PDZ were constructed using measures that resulted in an ERI at or
below the proposed design or the DOE Zero Energy Ready Home “Target Home” for single household or
“Dwelling Design” for multihousehold ERI, as previously submitted.
The third-party inspector or rater must certify that all requirements have been met and provide
documentation that the energy measures and the reduction in total annual energy use were achieved.
3 Note that on-site renewable energy generation may not be used to qualify a home for the
DOE Zero Energy Ready Home Target Home ERI requirements but can be used to achieve
additional ERI score reductions needed for homes larger than the Benchmark Home.
