P2-6. Enhancement
of
the Whole Building Diagnostician > Conclusions
Conclusions:
The enhanced features of the WBD will promote wider use by building operators.
Data collection, as reported in Project 2.4, is a significant barrier to
effective use of the WBD on line. The WBD documentation provides instructions
for creating files for batch processing by the WBD, which removes most
of the difficulties associated with data collection.
Commercialization potential:
-
The WBD software may be licensed from Battelle.

Recommendations:
Standardization of data collection and access to data from building automation
systems should be pursued at the national level through organizations such
as ASTM, ASHRAE, or a government agency.
Full commercialization of the WBD or derivatives
will require field
testing and should be
supported through
a future Energy Commission
project, or a CPUC
program.
Benefits to California:
Based on new data regarding the characteristics
of California building
stock and statewide
energy use, the projected
benefits of this
project are updated
as follows:
Updated Baseline:
The GWh savings estimated in the original
projected outcome
was based on a baseline
load of 74,677 GWh/yr
for the entire State.
The Commission's
figure for Year 2000 is
91,771 GWh/yr. The
WBD technology can be
applied in buildings
that have energy management
and control systems,
which constitute about
29% of the State
commercial and institutional
building floor area
and 29% of the statewide
electric load. This
is based on the prevalence
of EMCSs in Pacific
Gas and Electric Company's
territory. The baseline
load for the WBD's
WBE module would
be about 23,700 GWh per
year.
Updated Outcome:
Assuming that the WBD's Whole Building Energy
diagnostic module could be applied to 20%
of the baseline building load, and that 5%
savings could be achieved, the total savings
would be about 237 GWh/yr.
