Developing Energy Consumption Estimates by End Use for EIA's Buildings Surveys : 

Developing Energy Consumption Estimates by End Use for EIA's Buildings Surveys Residential Energy Consumption Survey (RECS) Commercial Buildings Energy Consumption Survey (CBECS)

RECS: 

RECS Fielded in 1978, 1980, 1981, 1982, 1984, 1987, 1990, 1993, 1997, 2001 Next RECS: 2005

RECS Universe: Occupied Primary Housing Units: : 

RECS Universe: Occupied Primary Housing Units: Covered: Single family detached homes Town homes Mobile homes Individual apartment units

RECS Universe: Occupied Primary Housing Units:: 

RECS Universe: Occupied Primary Housing Units: Not covered: Second homes Vacation homes Group quarters (college dorms, military barracks) Common areas in apartments

RECS Sample Design : 

RECS Sample Design Area probability design 116 primary sampling units 1,460 secondary sampling units

RECS Household Data Collection: : 

RECS Household Data Collection: Personal on-site interview with occupants Rental agent contacted to verify data on units in apartments buildings

RECS Energy Consumption and Expenditures Data : 

RECS Energy Consumption and Expenditures Data Obtain billing data from suppliers No Submetering for end-use data Use regression-based procedure to estimate consumption by end use

RECS End Uses: 

RECS End Uses Space heating Water heating Air conditioning (electricity) Appliances Refrigerators (electricity)

CBECS: 

CBECS Fielded in 1979, 1983, 1986, 1989,1992, 1995, 1999 Next CBECS: 2003

CBECS Universe: Commercial Buildings : 

CBECS Universe: Commercial Buildings Over 1,000 square feet Non-residential buildings Non-industrial buildings Non-agricultural buildings

CBECS: Examples of In-scope Buildings Types: 

CBECS: Examples of In-scope Buildings Types Office/professional buildings (including government buildings) Laboratories Food sales Food service

CBECS: Examples of In-scope Buildings Types, Continued: 

CBECS: Examples of In-scope Buildings Types, Continued Retail Service Strip malls and enclosed malls Lodging (hotel, motels, and college dorms)

CBECS: Examples of In-scope Buildings Types, Continued: 

CBECS: Examples of In-scope Buildings Types, Continued Public assembly Warehouses Religious worship Schools

CBECS: Examples of In-scope Buildings Types, Continued: 

CBECS: Examples of In-scope Buildings Types, Continued Public order and safety (fire stations and police stations) Hospitals and nursing homes Vacant buildings Other

CBECS Out-of-scope Structures: 

CBECS Out-of-scope Structures Buildings Under 1,000 square feet That are primarily residential That are primarily industrial That are primarily agricultural On military bases and other secure sites On industrial establishments

CBECS Out-of-scope Structures, Continued: 

CBECS Out-of-scope Structures, Continued Water towers Parking garages Power plants Grain silos Mobile or temporary offices

CBECS Sample Design: 

CBECS Sample Design Area probability design Supplemented by a list sample Large buildings Buildings on large universities Hospitals Government buildings

CBECS Buildings Characteristics Data Collection: 

CBECS Buildings Characteristics Data Collection Mostly personal interview (telephone interviews some years) May interview multiple respondents for one building  

CBECS Energy Consumption and Expenditures Data: : 

CBECS Energy Consumption and Expenditures Data: Obtain energy consumption and expenditures data from occupants Contact supplier when occupants cannot provide data  No Submetering for end-use data Use model/regression based procedure to estimate consumption by end use

CBECS End Uses: 

CBECS End Uses Space heating Water heating Air conditioning/cooling Cooking (electricity and natural gas) Appliances/other

CBECS End Uses, Continued: 

CBECS End Uses, Continued Electricity: additional end uses Ventilation Lighting Refrigeration Office equipment
