Executive Summary

There is a pressing need among residential retrofit market stakeholders (homeowners, 

contractors, researchers and utility and government program administrators) to understand how 

collections, or packages, of retrofit measures affect home energy use. The combined effects of 

multiple measures can be significantly different than the effects of individual retrofit measures. 

The higher levels of energy savings that are currently being targeted by the Department of 

Energy require implementation of multiple measures. It is important that interactions between 

measures be considered when determining the costs and benefits of advanced retrofit strategies. 

The impacts of these interactions cannot generally be determined using historical data from 

retrofit programs that target a single measure. This document provides a reference point that 

stakeholders can consult and use to educate themselves about how to most cost effectively 

achieve significant energy savings in existing homes. The most immediate audiences are 

stakeholders for the Department of Energy’s Better Buildings Neighborhood Program and 

Building America program. However, the information is equally useful for others who need an 

initial point of reference when choosing between myriad retrofit options for meeting their own 

cost and energy savings needs. 

This document presents a simple starting point to determine the most cost-effective Energy 

Savings Measure Packages (ESMP) for existing homes to achieve 15% and 30% savings in 37 

locations across the United States. These packages are optimized for minimum cost to 

homeowners for known source energy savings given the local energy cost, climate and prevalent 

building characteristics (i.e. foundation types). To provide consistency among grantees, the 

reference home for each retrofit energy savings optimization is based on the definition provided 

by NREL (Polly et al 2011). Details on the reference houses for Mixed Fuel and All Electric

houses are provided in Table 2 and Table 5 respectively. 

The information in the tables was developed using state-of-the-art building energy simulation 

software, BEopt (Building Energy Optimization) (Christensen et al 2006) and reflects advanced 

energy models for a variety of retrofit measures. Climate-related details that are provided in 

Table 2 and Table 5 provide details on the reference buildings and measures that were enabled in 

the optimizations. Summary tables for the 15% and 30% packages are provided in Tables 3 and 4 

(Mixed Fuel Prototype) and Tables 6 and 7 (All Electric Prototype). Additionally, summary 

tables sorted by Building America Climate Zones are provided for the 15% and 30% packages 

for both the Mixed Fuel and All Electric Prototypes in Tables 8 through 11. 

Optimum retrofit packages for higher energy savings levels are also provided in the Appendix 

for each location, of up to 60% savings in some instances. The analysis period is 30 years with 

an inflation rate and discount rate of 3%. The retrofit measure capital costs are financed via a 

five-year loan at an interest rate of 7%. All measure costs are assumed to be installed capital 

costs taken from NREL’s National Residential Efficiency Measures Database (NREL 2011).

Appendix: National Pathways Analysis - Detailed Cost and 

Performance Results for All Locations, Measures, and 

Performance Levels

The following graphs describe optimal retrofit packages for locations across the United States. 

The tables describe these packages according to increasing source energy savings. The average 

annual dollar savings to the homeowner is also included; this dollar savings represents the 

average annual net savings including utility bill savings due to lower energy bills and the 

additional costs associated with paying for the retrofit measures. A positive number represents 

net savings to the homeowner relative to not implementing any of the measures; a negative 

number represents a net cost. Two levels of energy savings are highlighted, 15% and 30%, which 

are the goals for the Better Buildings Neighborhood Program and Building America programs, 

respectively.

The graphs show the average annual dollar savings to the homeowner for each level of energy 

savings. All simulations performed in BEopt appear in the graph as points. Each point represents 

a different package of energy savings measures. The dark line shows the package that saves the 

homeowner the most money for a given level of energy savings. Retrofit packages on this line 

represent the optimal path to achieving cost effective energy savings. Each optimal retrofit 

package is shown in the corresponding table.
