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
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
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
so electricity use only is available for SCE and gas and electricity for
PGE. Similarly, geographic coverage for CEUS is limited to the
territory of these utilities. The following are used in
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
use reported in the survey, PGE's analysis and simulation results are
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
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
US ARCH | CBSG | HPCBS | EETD | BTD | LBNL
This survey involved about 500
and targeted the following business types: Hotels/Motels, Elementary and
Secondary Schools, Colleges and Universities, Hospitals and Clinics, and
This project has been funded in part by the California Energy Commission Public
Interest Energy Research program under the
Building Systems project.
