6.1 P URPOSE O F THE DOCUMENT

**This c**  **hapter 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 d**  **etermines 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 O PERATING H OURS

**To characterize**  **t he**  **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** 

**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 t**  **he residential**  **sector, DOE**  **uses RECS**  **building data**  **and LMC**  **residential sector** 

**operating hour**  **data to**  **develop a**  **distribution of**  **annual operating**  **hours for**  **IRL and**  **GSFL. 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 u**  **ses 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.**

**To estimate**  **f ive**  **of the**  **most likely**  **annual operating**  **hour characteristics**  **of IRL**  **in the** 

**residential sector**  **in the**  **NIA, DOE**  **uses information**  **from a**  **residential IRL**  **annual operating** 

**hour distribution**  **by room**  **type developed**  **with data**  **from LMC**  **and RECS**  **(Figure 6.2.3).**  **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**

6.3 R ESULTS O F THE ENERGY USE CHARACTERIZATION

**This s**  **ection 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**  **efficacy levels**  **(ELs).**

6.3.1 G eneral S ervice Fluorescent Lamps

**Using a**  **nnual 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.**  **residential, commercial,**  **and industrial**  **sectors**

**are 789**  **hours, 3,435**  **hours, and**  **4,795 hours,**  **respectively. For**  **the residential**  **lamp failure**  **event,**

**however, residential**  **high operating**  **hours of**  **1,210 hours**  **per year**  **are used.**  **This is**  **because a** 

**5 measure**  **life report**  **has shown**  **that ballasts**  **in the**  **residential sector**  **last approximately**  **15 years.** 

**6­9** 39**The usage**  **of 1,210**  **operating hours**  **leads to**  **a baseline**  **lamp lifetime**  **of approximately**  **12.5**

**years, which**  **allows the**  **lamp failure**  **event to**  **occur. The**  **usage of**  **789 hours**  **would result**  **in a** 

**ballast reaching**  **the end**  **of its**  **life before**  **a lamp**  **failure. 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**  **with ballasts**  **of different**  **ballast factors**  **to adjust**  **light**
