CEUS


The California Commercial End-Use Survey (CEUS) was last conducted in 1995.  CEUS is a comprehensive buildings characteristic survey sponsored by the California Energy Commission (CEC).  In the past this survey was contracted out to the three major California electric utilities: Pacific Gas & Electric (PGE), Southern California Edison (SCE), and San Diego Gas & Electric (SDGE).  The actual surveys were conducted through on-site interviews performed by companies contracted to the utilies.  CEUS has been largely underutilized as it has not been available to the general public.  The next CEUS to be released will be conducted by a single contractor and will be made publicly available in some form.

The CEUS data currently available to us is thus divided into 5 separate surveys conducted between 1992 and 1997 by the various utilities.  Data from SDGE was not used as energy use was not provided to us.  The only energy use reported by SCE and PGE was for the energy use provided by the utilities conducting the survey, so electricity use only is available for SCE and gas and electricity for PGE.  Similarly, geographic coverage for CEUS is limited to the service territory of these utilities. The following are used in Cal-Arch:

1996 PGE CEUS
This survey involved nearly 1000 commercial sites chosen to represent the commercial customer base in PGE's electric service territory.  While Cal-Arch utilizes the actual energy use reported in the survey, PGE's analysis and simulation results are reported in the 1999 Commercial Building Survey Report

1992 SCE CEUS
This survey involved approximately 700 sites of which 300 were allocated to a high-resolution survey and 400 were allocated to a low-resolution survey according to  SCE's stratification methodology.  The resolution of the survey does not affect the data used for Cal-Arch.  The building types targeted in this survey were Offices, Restaurants, Retail Stores, Food Stores, Refrigerated Warehouses, and Nonrefrigerated Warehouses. 

1995 SCE CEUS
This survey involved about 500 locations and targeted the following business types: Hotels/Motels, Elementary and Secondary Schools, Colleges and Universities, Hospitals and Clinics, and Miscellaneous Commercial.
