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 lamp**  **and lamp­and­ballast**  **designs DOE** 

**considers in**  **the rulemaking**  **analyses. The**  **results of**  **this analysis,**  **which represent**  **typical energy** 

**consumption in**  **the field,**  **are critical**  **inputs to**  **the life­cycle**  **cost (LCC)**  **and payback**  **period**

**(PBP) analyses,**  **described in**  **Chapter 8,**  **and the**  **national impact**  **analysis (NIA),**  **described in** 

**Chapter 10.**  **DOE needs**  **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**  **lamp­and­ballast**

**designs using**  **information on**  **their rated**  **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 lamp­and­ballast**  **designs. 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 OPERATING HOURS

**To characterize**  **the country’s**  **average use**  **of lighting**  **for a**  **typical year,**  **DOE develops** 

**annual operating**  **hours by**  **sector and**  **lamp category**  **(i.e., general**  **service fluorescent**  **lamps**

**(GSFL) and**  **incandescent reflector**  **lamps (IRL)).**  **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**  **13 census**  **divisions and**  **large States,** 

**building types,**  **and lamps**  **for all**  **sectors. a** 

**In conjunction**  **with data**  **from the**  **U.S. Lighting**  **Market Characterization:**  **Volume I** 

**1 (LMC), DOE**  **uses data**  **from the**  **Energy Information**  **Administration’s (EIA)**  **2003 Commercial** 

**2 Building**  **Energy Survey**  **(2003 CBECS), 2001**  **Residential Energy**  **Consumption Survey**  **(2001**

**3 4**  **RECS), and 2002**  **Manufacturer Energy**  **Consumption Survey**  **(2002 MECS). 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** 

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

**These operating**  **hours are**  **broken down**  **by application**  **for the**  **commercial and**  **industrial sectors,** 

**b and**  **room type**  **for the**  **residential sector.** 

**a Census**  **divisions include**  **New England,**  **Middle Atlantic,**  **East North**  **Central, West**  **North Central,**  **South Atlantic,** 

**East South**  **Central, West**  **South Central,**  **Mountain, and**  **Pacific. Large**  **States include**  **California, Florida,**  **New York,** 

**and Texas.**  **Sectors include**  **residential, commercial,**  **and industrial.** 

**b Residential**  **sector room**  **types include**  **bathroom, bedroom,**  **closet, dining**  **room, family**  **room, garage,**  **hall, kitchen,** 

**living room,**  **office, outdoor,**  **utility room,**  **and other.**  **Commercial and**  **industrial sector**  **applications include** 

**assembly, athletic,**  **bathroom, boarding,**  **class, dining,**  **display, exit,**  **ext­archi, ext­park,**  **exit­sign, exterior,**  **food**

**preparation, hall,**  **healthcare, office,**  **ship/rec, shop,**  **storage, task,**  **unknown, and**  **utility.**

**6­1 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**  **IRL. The**  **2001 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 of**  **IRL in**  **these rooms.**  **By using**  **probabilities derived**  **from RECS,** 

**the LCC**  **model selects**  **a building**  **of a**  **certain type**  **and census**  **division or**  **large State.**  **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 level,**  **rather than**  **at the**  **room**

**level, because**  **DOE believes**  **it more**  **closely represents**  **the impact**  **on an**  **individual consumer.** 

**However, DOE**  **does use**  **operating hour**  **data at**  **the room**  **level to**  **perform LCC**  **sensitivity results** 

**(Appendix 8B).** 

**DOE does**  **not develop**  **an operating**  **hour distribution**  **for GSFL**  **in the**  **residential sector** 

**for two**  **reasons. First,**  **DOE does**  **not analyze**  **GSFL in**  **the residential**  **sector; second,**  **the LMC** 

**does not**  **provide data**  **on this**  **lamp type**  **in this**  **sector. If**  **DOE determined**  **that analysis**  **in this** 

**sector were**  **necessary, it**  **could use**  **the distribution**  **of operating**  **hours of**  **GSIL, which**  **may**

**approximate the**  **operating hour**  **profile of**  **GSFL in**  **the residential**  **sector. Alternatively,**  **DOE**

**could develop**  **a distribution**  **of operating**  **hours from**  **another data**  **source.**

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

**commercial sector**  **for GSFL**  **and IRL.**  **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 DOE**  **believes 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 population**  **information from**  **the 2007**  **census 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**  **operating hours**  **per lamp**  **type per**  **sector.**

**Because the**  **NIA does**  **not use**  **Monte Carlo**  **analysis, it**  **does not**  **typically use**  **a**

**distribution of**  **data for**  **its inputs.**  **However, in**  **the NIA,**  **DOE uses**  **several values**  **for the**  **annual**

**operating hours**  **for longer­lived**  **IRL replacement**  **technologies (**  i.e.

**, reflector**  **CFL). DOE**  **uses**

**multiple annual**  **operating hours**  **for these**  **longer­lived lamps**  **because the**  **variation in**  **operating**

**hours has**  **a greater**  **impact on**  **their service**  **lifetimes. A**  **more accurate**  **representation of**  **the range** 

**of service**  **lifetimes of**  **these lamps**  **allows for**  **a better**  **projection of**  **shipments by**  **spreading out** 

**the replacement**  **cycle appropriately.**  **DOE does**  **not use**  **multiple annual**  **operating hours**  **for IRL** 

**or GSFL**  **because the**  **operating hours**  **do not**  **create as**  **large a**  **spread in**  **service lifetimes.** 

**6­3 To**  **estimate five**  **of the**  **most likely**  **annual operating**  **hour characteristics**  **of IRL**  **in the** 

**residential sector,**  **DOE uses**  **information from**  **a residential**  **IRL annual**  **operating hour** 

**distribution by**  **room type**  **developed with**  **data from**  **LMC and**  **RECS (Figure**  **6.2.2). DOE**  **uses**

**the mean**  **(884 hrs/year)**  **and standard**  **deviation (230**  **hrs/year) of**  **this distribution**  **to develop**  **a**

**normal distribution.**  **From this**  **normal distribution,**  **DOE selects**  **five different**  **annual operating** 

**hours to**  **represent the**  **annual operating**  **hours of**  **approximately 20**  **percent of**  **residential IRL** 

**sockets. Table**  **6.2.2 lists**  **the five**  **annual operating**  **hours DOE**  **uses in**  **the NIA.**

6.3 RESULTS OF THE ENERGY USE CHARACTERIZATION

**This section**  **presents the**  **annual energy**  **use estimates**  **for GSFL**  **and IRL.**  **DOE calculates** 

**the annual**  **energy consumption**  **using annual**  **operating hours**  **and power**  **rating estimates.**  **The**

**annual energy**  **consumption results**  **use average**  **annual operating**  **hours. 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).** 

6.3.1 General Service Fluorescent Lamps

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

**energy consumption**  **of the**  **entire lamp­and­ballast**  **system. The**  **following paragraphs**  **detail (1)** 

**the power**  **ratings for**  **all the**  **GSFL systems**  **DOE assesses**  **in the**  **LCC and**  **PBP analysis**  **for each** 

**product class**  **representing GSFL;**  **and (2)**  **average annual**  **energy consumption**  **per lamp­and** 

**ballast system**  **using the**  **U.S. weighted**  **average of**  **annual operating**  **hours in**  **each sector.**  **The**

**average GSFL**  **annual operating**  **hours for**  **the U.S.**  **commercial and**  **industrial sectors**  **are 3,435** 

**and 4,795,**  **respectively. Appendix**  **6A presents**  **the energy**  **consumption rates**  **for the**  **systems**

**DOE uses**  **in the**  **NIA. As**  **discussed in**  **the engineering**  **analysis (Chapter**  **5), DOE**  **pairs lamps** 

**6­8** 39**with ballasts**  **of different**  **ballast factors**  **to adjust**  **light output,**  **creating a**  **number of**  **system**

**designs.**
