Introduction
In association with the 2014–2018 Energy Efficiency Portfolio (EEP), the Interstate Power and Light (IPL)
Savings Reference Manual (SRM) provides guidance for measuring the resource savings from standard
energy-efficiency measures. The SRM was developed for estimating annual electric and natural gas
energy savings and coincident peak demand savings for a selection of energy-efficient technologies and
measures.
The savings algorithms provided in this document were developed using industry-accepted methods.
The algorithms were largely guided by the findings of the joint utility Assessment of Energy and Capacity
Savings Potential in Iowa (Statewide Assessment) dated February 28, 2012 and other sources. The
Statewide Assessment is a comprehensive study of energy efficiency and demand response savings
potential in the service territories of Iowa’s three investor-owned utilities: IPL, Black Hills Energy (BHE),
and MidAmerican Energy Company (MEC). The Assessment focused on reporting potential savings over
a 10-year planning horizon, from 2014 to 2023.
To assess the impacts of each measure, and the programs as a whole, algorithms use customer data as
input values. Savings per measure are either deemed or based on engineering algorithms that can be
used to estimate savings based on the information provided by participants on a rebate application
and/or equipment records stored in IPL’s or other organizations’ databases such as ENERGY STAR®, the
Air Conditioning, Heating and Refrigeration Institute (AHRI), and the Consortium for Energy Efficiency
(CEE).
The SRM’s resource energy savings methodologies may be represented in one of three ways: (1) fully
deemed; (2) partially deemed algorithm; or (3) fully calculated algorithms. The majority of the SRM
contains fully deemed and partially deemed algorithms.
1.
2.
Fully Deemed: A fully deemed measure receives a stipulated (deemed) savings value. A
measure often has deemed savings when savings have been found to be stable for certain,
standard measure types when they are used in common applications and/or in cases where
collecting participant-specific data for calculating savings is difficult or impossible. Deemed
savings for a given measure may be provided for a range of different application scenarios
such as for specific building types. In cases where fully deemed savings are used in the SRM
the savings are generally based on the Statewide Assessment results.
Partially Deemed Algorithm: Algorithms can be used to calculate savings in cases where
input parameters are stipulated or determined based on project-specific conditions.
Partially deemed algorithms are used for measures with commonly accepted formulas and
rigorously reviewed inputs. Partially deemed algorithms allow participant-specific data to be
applied but minimize the data-collection burden by using preapproved, standard inputs for
uncollected variables. Partially deemed algorithms can also prove effective with weatherdependent measures (such as furnaces) where look-up tables provide variables such as fullload hours, based on the climate zone.
1
3.
Fully Calculated Algorithms: Fully calculated algorithms are applied only with custom
measures, where individual projects vary significantly in terms of installed measure
parameters and other factors that affect energy use and savings.
The 2014–2018 EEP is composed of 25 programs targeting single family and multifamily residential, lowincome residential, commercial, industrial, and agriculture customers. Of those 25 programs, 15 offer
direct financial incentives, direct installation measures, and/or technical assistance for customer actions
to improve building efficiency and two programs offer incentives for customer actions to reduce peak
demand. However, the SRM addresses only the 15 energy-efficiency programs that generate measurebased savings. IPL designed its Energy-Efficiency Portfolio to offer customers in every sector the
flexibility to participate at many levels, based on their individual needs and building type.
The SRM algorithms support programs within the EEP where fully and partially deemed algorithms are
used to estimate savings. The savings algorithms are incorporated into IPL’s customized energyefficiency tracking system, Tool for Reporting Energy Efficiency Savings (TREES), to calculate and track
rebate payments and impacts. TREES receives data feeds from IPL’s customer billing system, which
ensures the customer’s account is active and that the service type (electric, natural gas, or both) is
accurately reflected when calculating measure savings.
In addition to the SRM, TREES relies on energy-savings tracking and documentation by program
implementation contractors, such as WECC, Michaels Engineering, CLEAResult, and Iowa Community
Action Program (CAP) agencies, as shown in Table 1.

spreadsheet workbooks are available upon request.

Update Process
Annual updates to this SRM will be published prior to the filing of IPL’s annual report each year to
reflect the electric and natural gas energy savings assumptions in place for the year. The updates will be
incorporated in the original document and changes will be indicated in Appendix F: Revision History
table. This regular update process is intended to ensure the SRM remains relevant and useful by:
•
Presenting validated savings calculations for any new measures added to the IPL programs since
the previous year’s update;
•
Eliminating measures that are no longer being offered by IPL; and
•
Updating information on existing measures to reflect new research findings and technology
changes.

Calculated from SEERBASE, methodology from NREL Building America Research
Benchmark Definition 2009, Equation 4: EER = -0.02×SEER2+1.12 × SEER. SEER based
on Federal Code, 2006 and 2015, 10 CFR 430.32(c)(2) and 10 CFR 430.32(c)(3).
Entered from application form or AHRI database. For heat pumps larger than 65
MBtuh, it is assumed multiple air-source heat pumps are installed that are less than
65 MBtuh maintaining the same baseline.
Federal Code, 2006 and 2015, 10 CFR 430.32(c)(2) (converted HSPF to COP, dividing
HSPF by 3.412).
Based on Cadmus analysis of the relationship between part- and full-load capacities
from building simulations of BEopt (Building Energy Optimization) to generate the
energy models. The models were calibrated using Cadmus metered data of 13 highefficiency multi-stage GSHP models functioning in both part- and full-loads.
GSHPs produce higher cooling capacity than heating capacity. A 4-ton GSHP might
produce 50,000 BTUs of cooling but only 37,400 BTUs of heating at peak cooling and
heating conditions, respectively. In Des Moines, homes demand more heating than
cooling. This means that the GSHP must run longer at full-load to heat a home, but
can meet the homes cooling load with less capacity. As a result, the part-load
adjustment has a proportionally larger impact on the cooling season usage. Based on
Cadmus analysis of the relationship between part- and full-load capacities from
building simulations of BEopt (Building Energy Optimization) to generate the energy
models. The models were calibrated using Cadmus metered data of 13 highefficiency multi-stage GSHP models functioning in both part- and full-loads.

Central Air Conditioner system compliant with federal standard; with a
minimum SEER/EER of 13.0/11.2.
Room AC standard changes in 6/1/2014. IPL adopts mid-year code changes the
first of the year following the change (e.g., the room AC change due 6/1/2014
would be implemented by IPL programs and TREES on 1/1/2015). All analysis
and assumptions are based on the first of the year following the mid-year code
change.
For 2014 Program Year (federal standard effective October 2000 through
June 1, 2014):
-Room AC system that is ENERGY STAR.
After 2014 Program Year (federal standard effective June 1, 2014):
-Room AC system that is ENERGY STAR, rated in CEER. This new ENERGY STAR
criteria rating had not been announced as of July 29, 2013.
-Taking a 8,000-13,999 Btu unit, the new federal baseline for room AC will be
roughly EER = 11 (CEER = 10.9), rendering the current ENERGY STAR measure
with EER 10.8 to incur negative savings.
-Recommend update to energy-efficiency program requirements for the 2015
program year. Update calculation workbook once new criteria becomes
available.
-Efficiency (in EER and/or CEER).

Savings are captured by load sensing advanced power strips (APS) also known
as smart strips. Smart strips typically have one master or controller outlet,
several controlled or switched outlets, and one or two uncontrolled or alwayson outlets. The controlled outlets will automatically stop drawing power when
the homeowner turns off the controller device. This creates energy savings by
reducing the power draw from the controlled devices’ standby mode.

Cadmus has conducted many evaluations of refrigerator and freezer recycling programs
and, as part of these studies, has developed regression models to estimate the annual
consumption of recycled appliances, based on age, weather, configuration (side-by-side,
top freezer, etc.), and whether the unit is primary or secondary. Consumption used as the
dependent variable derived from metering of recycled units. Applied Des Moines weather
along with data from IPL’s 2011 program tracking database (age and configuration) to
these regression parameters estimated average gross savings for refrigerators and freezers.
This analysis produced 1,239 kWh and 1,029 kWh for refrigerators and freezers,
respectively. The final annual kWh savings values are subsequently calculated by applying
the part-use factor and the annual de-rating factor.

Savings were calculated assuming existing 10,000 BtuH EER 7.7 RAC units were recycled
and replaced by EER 9.8 RAC units, with the recycling percentage of 76%.( OH TRM—Based
on Nexus Market Research Inc., RLW Analytics, December 2005; “Impact, Process, and
Market Study of the Connecticut Appliance Retirement Program: Overall Report.” Report
states that 63% were replaced with ENERGY STAR units and 13% with non-ENERGY STAR.
OH TRM assumes this formula that all are non-ENERGY STAR since the increment of savings
between baseline units and ENERGY STAR would be recorded by the Efficient Products
program when the new unit is purchased.)

Sector(s)
Program
The program offers two participation options: a measure-based
(prescriptive) approach and a performance-based approach. For the
measure-based option, homeowners or builders must meet the program
specifications by installing the prescriptive measures included in a builder
option package (BOP). The performance-based option focuses on achieving a
minimum Home Energy Rating System (HERS) score in one of two
performance tiers. Qualified air source heat pumps must have SEER/EER
15/12.5 (Split System) and HSPF 8.5 or higher ratings than conventional
models. Qualified central air conditioners have SEER/EER 15/12.5 (Split
System) or higher ratings than conventional models. Efficient furnaces with a
quality installation use less energy than conventional furnaces with a
minimum of 94% AFUE. A high-efficiency water heater reduces standby
losses and therefore proves more efficient than a standard gas water heater.
Tank-less water heaters provide hot water at a preset temperature when
needed and without storage, thereby reducing or eliminating standby losses.
A heat pump water heater moves heat from a warm reservoir (such as air),
transferring this heat into the hot water system.

The Weatherization Program is a collaborative utility program, implemented jointly through the Iowa
Utility Association (IUA). IPL contributes program funding through the Iowa Department of Human
Rights (DHR), which in turn, supports CAP agencies to perform energy assessments and purchase and
install qualifying energy-efficiency measures in residences occupied by low-income families.
The Weatherization Program is delivered to homeowners and renters with income levels at or below
200% of the FPL. Homes occupied by the elderly, disabled, and families with children under the age of
six receive priority for weatherization assistance, as do households with high energy usage. The CAP
agencies market and deliver the program to low-income customers, and the DHR’s Division of
Community Action Agencies administers the program.
The program provides a comprehensive home energy audit and the installation of cost-effective energyefficiency measures, including: wall, attic, and foundation insulation; furnace replacement; refrigerator
and freezer replacement and/or removal; water heater replacement; water heater insulation wrap; hot
water pipe insulation; low-flow showerheads; faucet aerator replacement; and CFLs. Other services
provided falling outside the involvement of the utilities include: evaluation of the health and safety of
the home; exhaust ventilation; installation of smoke and carbon monoxide detectors; and some minor
home repairs. Customers receive all measures free of charge. Upon completion of weatherization work
and equipment installation, CAP agencies conduct a final home inspection to ensure quality work.
CAP agencies track and capture all savings and provided these to the IPL for program tracking. The SRM
does not summarize measure algorithms for this program.

improving efficiency and reducing their energy expenditures. Local CAP agencies provide energy
education workshops for participating households. Participants receive a free kit, containing multiple
low-cost, easy-to-install, energy-efficiency measures and a survey about participants’ experience with
the program.
Eligible households, with incomes at or below 200% of the FPL, receive the program free of charge.

Through its Multifamily and Institutional Efficiency Improvements (MIEI) Program, IPL provides funding
to support energy-efficiency improvements in eligible multifamily properties and institutional facilities
where low-income customers reside. MIEI includes two components:
1. A free assessment with direct-installation of low-cost, energy-efficiency measures for tenant
units and common areas; and
2. Enhanced prescriptive rebates for multifamily buildings that meet Section 81 housing
qualifications.
The program offers a comprehensive energy assessment and direct-install measures at no cost to
customers. IPL determines incentives on a per-measure basis; however, the total utility incentive for
each project is targeted to be 40% of the total cost of upgrades.
IPL administers and implements the program with support from a program contractor. IPL also
coordinates this program with MEC, BHE, and the IUA. The program contractor tracks and captures all
savings and provides these for IPL’s program tracking. The SRM does not summarize measure algorithms
for this program.

program strives to encourage energy-efficient practices in the homes of limited-income customers,
defined as households with incomes that 50% to 100% above the current limit associated with federal
weatherization assistance guidelines. CAP agencies market and deliver HES to these limited-income
customers.
IPL pays the full cost for audits and direct-installation measures, and covers 90% of the installed cost of
energy-efficiency measures recommended by CAP agency energy auditors. Eligible measures include:
wall, attic, and foundation insulation; furnace replacement; refrigerator and freezer replacement and/or
removal; water heater replacement; water heater insulation wrap; pipe insulation; low-flow
showerheads; faucet aerator replacement; and CFLs. CAP agencies may also evaluate the health and
safety of a home,2 install smoke and carbon monoxide detectors, and perform minor home repairs.
Upon completion of weatherization work and equipment installation, the CAP agency conducts a final
home inspection to ensure quality work.
CAP agencies track and capture all savings, and provide these to the IPL for program tracking. The SRM
does not summarize measure algorithms for this program.

Based on Cadmus analysis of the relationship between part- and full-load capacities from
models. The models were calibrated using Cadmus metered data of 13 high-efficiency
multi-stage GSHP models functioning in both part- and full-loads.
GSHPs produce higher cooling capacity than heating capacity. A 4-ton GSHP might produce
50,000 BTUs of cooling but only 37,400 BTUs of heating at peak cooling and heating
conditions, respectively. In Des Moines, homes demand more heating than cooling. This
means that the GSHP must run longer at full-load to heat a home, but can meet the homes
cooling load with less capacity. As a result, the part-load adjustment has a proportionally
larger impact on the cooling season usage. Based on Cadmus analysis of the relationship
between part- and full-load capacities from building simulations of BEopt (Building Energy
Optimization) to generate the energy models. The models were calibrated using Cadmus
metered data of 13 high-efficiency multi-stage GSHP models functioning in both part- and
full-loads.

Ground HDD adjustment factor calculation based on HDD, winter ground temperature, and
weather bin data. Based on ground temperature of 53 degrees. (ASHRAE HVAC
Applications pg. 34.17) Weather bin data and HDD obtained from TMY3 Weather Data for
the weather station Des Moines International Airport. Ground temperature at 4-ft. depth is
assumed to have a temperature of 5 degrees below the temperature of the surface based
on: Figure 4, http://www.geo4va.vt.edu/A1/A1.htm
The initial R-value for a foundation or basement wall assumes zero or minimal existing
insulation, or that it has fallen down, resulting in an R-value equivalent to building
materials with only a small contribution of installed R-value (assume R-3).
Inferred from the 2011 assessment and the PA TRM 2013. The initial R-value for a wall
assumes zero or minimal existing insulation, or that it has fallen down, resulting in an
R-value equivalent to building materials with only a small contribution of installed R-value
(R-4.5). The construction materials (roughly R-3) and their thickness, based on building
simulation modeling using DOE-2.2 model (eQuest), inferred from the PA TRM. The
baseline R-value resulting assumption is R-7.5.

The Custom Rebates Program promotes energy-efficiency products and practices among commercial
and industrial customers. The program’s custom incentive structure gives energy users the flexibility to:
install a broad range of high-efficiency equipment not included in IPL’s Nonresidential Prescriptive
Rebates Program; or implement equipment optimization and/or operational and process changes that
reduce energy consumption and peak demand.
IPL nonresidential customers may qualify for custom rebates if they replace standard-efficiency
equipment with equipment and measures that provide energy and/or demand savings. The program
also offers energy-efficient training for facility managers and operators. Program incentives include:

Any measure or project not included in IPL’s Nonresidential Prescriptive Rebates Program or
Agriculture Sector Program due to size, scope, or unique characteristics of the energy-efficiency
equipment or measure;

New construction, additions, and remodeling projects that have progressed beyond the early
design phase;3

Design assistance to improve the efficiency of industrial processes;

Cost-effective and qualified combined heat and power projects;

Training on efficient building operations and efficient technologies for operations and
maintenance staff; and

Equipment optimization, retrocommissioning, or other operational and maintenance
improvements that ensure customer facilities’ continue performance over time.
The Custom Rebates Program offers incentives for a comprehensive set of energy-efficiency measures
and projects for existing buildings and new construction. Eligible efficiency measures may include:

incentives to commercial builders and developers who design and build new energy-efficient buildings
and facilities that exceed the current State of Iowa commercial building energy code.
IPL provides incentives to participants when they achieve a target level of energy savings above the
current State of Iowa building energy code. Construction incentives are designed to offset the additional
cost of constructing high-performance commercial buildings.
IPL offers four program tracks based on the planned project size and end use:
1) Program Track I targets the construction of commercial buildings up to 15,000 square feet in size
that are primarily design/build or design/bid/build construction projects. Participants in this
track must exceed current commercial energy-efficient code requirements by 15 percent.
2) Program Track II (formerly encompassed within the Custom Track) targets buildings larger than
15,000 square feet that are straightforward in design and may be on a fast design schedule.
Track II provides evaluation of efficiency options for one type of mechanical system solution. IPL
works with developers in this track to achieve energy savings between 15 and 40 percent above
the current commercial energy code.
3) Program Track III (formerly Custom Track) targets buildings larger than 15,000 square feet that
require more customized energy design. The program provides energy modeling of custom
efficiency strategies selected by the owner/design team. IPL works with developers in this track
to achieve energy savings between 15 and 40 percent above the current commercial energy
code.
4) Program Track IV (formerly Custom Plus Track) offers incentives and assistance to help building
owners or developers achieve energy savings that are 40 to 60 percent above current energy
351
code. This track also provides technical and certification support for participants to meet the
requirements of Leadership in Energy and Environmental Design (LEED), ENERGY STAR, Energy
Policy Act of 2005, 2030 Challenge, and other built-environment initiatives.
Participants work closely with IPL energy-efficiency staff. IPL provides incentives throughout the design
and implementation process, under the following protocols:

EDA: IPL provides free consulting to help customers identify the optimal mix of cost-effective
energy-efficiency strategies, such as building shell/envelope, window glazing, day-lighting design
and control, lighting design and control, heating and cooling systems, motors and pumps,
compressed air, and outside air. IPL pays incentives for design assistance services directly to the
third-party consultant.

Design Team Incentive: IPL provides a prescriptive design team incentive based on the
customer’s construction track. This incentive is intended to offset most or all of the expenses
incurred by participating in the EDA process. IPL provides the design team incentive following
submittal and review of construction documents.

Construction Incentives: IPL designed its construction incentives to cover a portion of the cost of
implementing strategies that result in energy savings of at least 15 percent above the State of
Iowa commercial building energy code. Incentive levels are based on the completed building’s
verified savings, and are paid approximately 60 days following occupancy of the new building.
Similar to the Custom program, Michaels Engineering tracks and captures all savings, following the
ASHRAE-90.1 standards and Technical Guide Book for new construction projects. IPL receives all
data and analysis for program tracking. The SRM does not summarize measure algorithms for this
program.

Sector(s)
Program
-Savings achieved by replacing an existing, old grain dryer with a new grain
dryer.
-Retrofit projects achieve electric savings by replacing old grain dryers with
new grain dryers that operate more efficiently due to design improvements,
increased capacity, increased production, and reduced hours of operation.
-The same electric savings are achieved in new construction projects
because the customer typically has the option of purchasing old or
refurbished grain dryers that are still on the market (per discussions with
Dave Warrington). These baseline grain dryers would cost less and have
efficiencies comparable to old grain dryers, and the savings are, therefore,
the same for new construction and existing buildings.
Electric
Agriculture-Specific
Existing old grain dryer with lower efficiency.
-Only electric projects may qualify. Combination or gas-only projects are
directed to the Custom Rebate program.
-Bushels/hr must be provided by the manufacturer, rated at 5 pts of
moisture removal per bushel.
-Variability in grain dryer type/savings for dryers larger than 2,000
bushels/hr is such that grain dryers of that size fit better with the Custom
Rebate program.

Based on Cadmus analysis of the relationship between part- and full-load capacities
from building simulations of BEopt (Building Energy Optimization) to generate the
energy models. The models were calibrated using Cadmus metered data of 13 highefficiency multi-stage GSHP models functioning in both part- and full-loads.
GSHPs produce higher cooling capacity than heating capacity. A 4-ton GSHP might
produce 50,000 BTUs of cooling but only 37,400 BTUs of heating at peak cooling and
heating conditions, respectively. In Des Moines, homes demand more heating than
cooling. This means that the GSHP must run longer at full-load to heat a home, but
can meet the homes cooling load with less capacity. As a result, the part-load
adjustment has a proportionally larger impact on the cooling season usage. Based on
Cadmus analysis of the relationship between part- and full-load capacities from
models. The models were calibrated using Cadmus metered data of 13 highefficiency multi-stage GSHP models functioning in both part- and full-loads.
