Short Term Energy Monitoring: What Does This Information Mean to the Facility Energy Manager?
Abstract
Engineers at the Energy Systems Laboratory at
Texas A&M University have completed short term
energy metering studies at a complex of offices in
northern Texas and several buildings on the Texas
A&M University campus during the past 18 months.
These studies typically consisted of installing
electrical metering at the, whole building level and
included sub-metering of selected circuits when
possible. Personnel would go through the entire
facility ensuring that all lighting, fan, and mechanical
systems were active and on. After a period of
approximately 10 minutes, a selected areas of the
building would be "turned off." This sequence was
repeated for all areas of interest in the facility. At the
end of the lighting test, air handlers, then chilling and
pumping equipment was turned off (if applicable)
and a final ten minutes of electrical use data taken.
In each of these facilities, lighting system load
verification was the primary goal and the data
provided a very good accounting for all buildings
studied. The northern Texas office buildings in
particular, were interested in these data for
comparison with a recently hired performance
contractor. The A&M study was a follow-up to an
earlier lighting study that had been conducted by the
campus energy office. Base electrical load data was
also determined from these tests. This paper presents
results of these studies and suggests that the method
is attractive to both contractors and facility energy
managers as well.
