CHAPTER 6. ENERGY USE CHARACTERIZATION 

6.1 PURPOSE OF THE DOCUMENT 

This chapter presents the methodology the U.S. Department of Energy (DOE) follows to 

estimate the annual energy consumption of the fluorescent lamp-and-ballast system designs DOE 

considers in the ballast rulemaking analyses. Because fluorescent lamp ballasts are designed to 

operate fluorescent lamps, DOE chooses the most common fluorescent lamp used with each 

ballast to develop representative lamp-and-ballast systems. Fluorescent lamps will not be 

regulated under the proposed ballast rulemaking; however, the input power of the complete 

lamp-and-ballast system is considered for the energy use analysis. The results of this analysis, 

which represent typical energy consumption in the field, are critical inputs to the life-cycle cost 

(LCC) and payback period (PBP) analyses (preliminary technical support document [TSD] 

chapter 8) and the national impact analysis (NIA; preliminary TSD chapter 10). DOE requires 

information on annual energy consumption to determine the potential energy and operating cost 

savings to consumers from the use of more efficient equipment. 

DOE determines the annual energy consumption of the lamp-and-ballast systems using 

information on their rated input power (i.e., the rate of energy they consume) and the way 

consumers use them (i.e., operating hours per year). The engineering analysis (chapter 5) 

discusses the power ratings of lamp-and-ballast systems. The following sections discuss the 

inputs and calculations DOE uses to develop annual operating hours and annual energy 

consumption for the products considered in this analysis. 

6.2 LAMP AND BALLAST SYSTEM OPERATING HOURS 

To characterize the country’s average use of lamp-and-ballast systems for a typical year, 

DOE develops annual operating hours by sector. For the LCC, DOE accounts for variability in 

operating hours by developing a distribution of operating hours for the LCC spreadsheet. The 

operating hour distributions capture variation across nine census divisions (New England, 

Middle Atlantic, East North Central, West North Central, South Atlantic, East South Central, 

West South Central, Mountain, and Pacific) and large States (California, Florida, New York, and 

Texas), building types, and lamp-and-ballast systems for three sectors (residential, commercial, 

and industrial). 

In conjunction with data from the U.S. Lighting Market Characterization (LMC) 

Volume 1,1

 DOE uses data from the Energy Information Administration’s (EIA) 2003 

Commercial Building Energy Survey (CBECS),2

 2005 Residential Energy Consumption Survey 

(RECS),3

 and 2002 Manufacturer Energy Consumption Survey (MECS).4 These EIA studies 

provide information on the distribution of U.S. buildings by building type and census division. 

The LMC, which is based on thousands of building audits and surveys, provides national-level 

data on annual operating hours by building type and lamp type for all sectors. These operating 

hours are divided by application (assembly, athletic, bathroom, boarding, class, dining, display, 

exit, exterior-architectural, exterior-parking, exit-sign, exterior, food preparation, hall, 

healthcare, office, ship/rec, shop, storage, task, unknown, and utility) for the commercial and 

6-1 

EERE-2007-BT-STD-0016 COMMENT 25
industrial sectors and room type (bathroom, bedroom, closet, dining room, family room, garage, 

hall, kitchen, living room, office, outdoor, utility room, and other) for the residential sector. 

DOE associates LMC operating hour data by building type with EIA data by building 

type and census division to derive annual operating hours by census division and large States. 

This allows DOE to correlate the electricity price distribution (chapter 8), and sales tax 

distribution (chapter 7) with the operating hour distribution by census division and large States in 

the LCC spreadsheet. The following paragraphs describe data sources DOE uses to develop 

annual operating hours by sector. 

For the residential sector, DOE uses RECS building data and LMC residential sector 

operating hour data to develop a distribution of annual operating hours for fluorescent lamp-andballast systems. The 2005 RECS data indicates the probability that a certain building type resides 

within a census division. The LMC indicates the occurrence of certain room types within a given 

building type and the operating hour characteristics in these rooms. DOE then uses aggregated 

data from the LMC to associate average annual operating hours per building type. DOE chose to 

aggregate operating hour data to the building rather than at the room level because DOE believes 

it more closely represents the impact on an individual consumer. However, DOE will use 

operating hour data at the room level to perform uncertainty results in the notice of proposed 

rulemaking (NOPR) stage of this analysis. 

DOE uses a similar approach to develop a distribution of annual operating hours in the 

commercial sector. However, instead of room type, DOE aggregates LMC annual operating hour 

data by application to develop average annual operating hours by building type. The 2003 

CBECS data indicates the probability a certain building type in a certain census division exists. 

Once the LCC model selects a building, DOE associates the aggregated LMC annual operating 

hour average with the building type selected. Like the residential sector, DOE chose to aggregate 

LMC operating hour data to the building level for the commercial and industrial sectors because 

it more closely represents the impact on consumers. 

To develop a distribution of annual operating hours in the industrial sector, DOE uses an 

approach consistent with that used for the commercial sector. The 2002 MECS data indicates the 

probability a certain building type exists. DOE aggregates LMC annual operating hour data by 

industrial application to develop average annual operating hours by building type. Once the 

model selects a building, DOE associates the aggregated LMC operating hour average with the 

building type selected. Because MECS does not provide the location of industrial sector 

buildings, DOE uses 2008 U.S. Census Bureau population information to establish the 

probability that a certain industrial building exists in a certain census division or large State. 

Table 6.2.1 summarizes the weighted average annual operating hours per sector.

Figure 6.2.3. Industrial Sector Annual Operating Hour Distribution by Building Type 

In the case of programmed-start (PS) ballasts operating two-lamp and four-lamp 4-foot 

MBP F32T8 lamps, DOE assumes that these lamp-and-ballast systems are operated on 

occupancy sensors in the commercial sector. Occupancy sensors detect the presence or absence 

of people within their coverage area and turn lights on and off accordingly, thereby reducing 

operating time and energy consumption. DOE examined a range of estimates for energy savings 

from occupancy sensors compiled in Esource5

 and assumes, based on this estimate, energy 

savings of 30 percent for operating lamp and ballast systems on occupancy sensors in the 

commercial sector. To account for these energy savings, DOE reduces average operating hours 

for affected lamp-and-ballast systems by 30 percent. Table 6.2.2 presents the adjusted average 

annual operating hours for PS lamp-and-ballast systems operating on occupancy sensors in the 

commercial sector.

6.3 RESULTS OF THE ENERGY USE CHARACTERIZATION 

This section presents the annual energy use estimates for fluorescent lamp-and-ballast 

system designs. DOE calculates the annual energy consumption using annual operating hours 

and input power rating estimates. DOE uses the annual energy consumption results in the LCC 

and PBP analyses and the NIA to calculate the operating cost of systems and estimate the 

potential energy savings of candidate standard levels (CSLs). 

Using annual operating hours and system rated input power ratings, DOE calculates the 

annual energy consumption of the entire lamp-and-ballast system. The engineering analysis 

(chapter 5) references both measured system input power and normalized system input power, 

with the latter used to normalize input power between baseline and standards-case systems to 

maintain the same approximate light output. 

Table 6.3.1 through Table 6.3.15 detail (1) the measured and normalized input power 

ratings for all the lamp-and-ballast systems DOE assesses in the LCC and PBP analysis for each 

product class; and (2) average annual energy consumption per lamp-and-ballast system based on 

measured and normalized input power, using the U.S. weighted average of annual operating 

hours in each sector. The average annual operating hours for the U.S. residential, commercial, 

and industrial sectors are 789, 3,435, and 4,795, respectively.
