### CHAPTER 11. LIFE

- CYCLE COST SUBGROUP ANALYSIS

11.1 INTRODUCTION

Chapter 8 describes the life

- cycle c ost (LCC) and payback period (PBP) analyses that

examine impacts of energy conservation standards on the U.S. population. In analyzing the potential

impact of new or amended standards on residential consumers, DOE further evaluates the impact on

identifiable groups of consumers (i.e., subgroups) that may be disproportionately affected by a

national standard level. The LCC subgroup analysis evaluates impacts by analyzing the LCC and

PBPs for subgroups of residential consumers.

For both clothes dryers and room air conditioners , DOE identified two consumer subgrou psthat warranted further study: (a) households composed of people 65 years of age or older (senioronly); and (b) households at or below the poverty line (low- income)

.



### DOE determined the impact on consumer subgroups for clothes dryers and room air
conditioners using the LCC Spreadsheet Model, which allows for the examination of particular
consumer subgroups. DOE has the ability to use the LCC Spreadsheet Model to analyze the LCC
for any subgroup by sampling only the data that apply to that subgroup (Chapter 8 explains in
detail the inputs to the model u sed in determining LCC and PBPs). As described in section 11.3,
the energy use and energy price characteristics of the two subgroups (senior -only and lowincome) are different than that for the general population.

This chapter describes the subgroup identification in further detail and gives the results of the
LCC and PBP analyses for the considered subgroups.



### 11.2 SUB G ROUPS DEFINITION

11.2.1 Senior

- Only Households

Senior-only households have occupants who are all at least 65 years of age. Based on the

DOE Energy Information Administration (EIA)’s Residential Energy Consumption Survey of 2005

(RECS), senior-only households comprise 17 percent of the country’s households. 1



### 11.2.2 Low- Income Households

As defined in the RECS sur vey, low-income households are considered to be those at or
below the “poverty line.” The “poverty line” varies with household size, head of household age,
and family income. Table 11.2.1 summarizes the income level baselines for selecting low

income households from the RECS sample. The RECS survey classifies 15 percent of the
country’s households as low- income.11 -2

- CYCLE COST AND PAYBA CK PERIOD

SUB G ROUP ANALYSIS

DOE performed the consumer subgroup analysis by analyzing the LCC and PBP of
senior-only, low-income , multi

- family, and manufactured households with the spreadsheet

models used for the LCC and PBP analysis.

Table s 11.3.1 and 11.3.2 summarize the household populations for clothes dryers and room

air conditioners , while T ables 11.3.3 and 11.3.4 summarize the weighted -average annual energy

use for the households analyzed in the consumer subgroup analyses. 

### These values are compared
against the weighted

- average values for the national sample.
