Hewlett-Packard (HP)
Company facility operators
had been optimizing the
campus’ energy use for
many years. However, with the onset of
California’s energy crisis, HP wanted to
be doing more to save energy and to help
avert rolling blackouts in their community.
Their energy management system (EMS)
had limited automation: cutting back
on HVAC and lighting loads was labor-
and time- intensive, involving the manual
adjustment of several controls spread
out over the vast campus. Such a system
did not allow them the flexibility to
curtail load and still maintain occupant
comfort, a high priority at HP.
The availability of funding from the California Energy Commission for the
installation of enhanced automation technologies served as a catalyst for HP
to move ahead with plans to modify the automation capability of their EMS.
HP traditionally used its EMS for monitoring temperatures and for operating
air-handlers and other mechanical HVAC equipment. However, control over lighting was limited.
Adding the desired level of automation involved linking the EMS to all lighting and HVAC
systems via direct digital controls (DDC). Roseville Electric, HP’s municipal electricity supplier,
secured and administered the California Energy Commission grant funds and played a key
role in shaping and implementing the project.
The project was a
resounding success.
We discovered very
quickly that we could
curtail demand any
day of the year, and
we did. Our historical
peak was 10.9 MW
and we were routinely
able to reduce that to
about 9.5 MW, saving
us not only energy,
but demand charges
as well.”
“
As utilities move toward time-of-
use metering, a business’ ability to
control utility costs by automating
energy use according to price will
become increasingly valuable.”
“
Before, in times of power shortages,
we would curtail by manually shutting
off selected circuit breakers. Now,
our enhanced energy management
system automates this process, saving
our staff valuable time and effort.”

Comparison of the two curves shows that demand

shaded areas.
HP Roseville Electrical Demand
pg_0003
As a result of these changes, HP is now able to shed up to 1.5 MW of peak
load, without disrupting occupants’ productivity or comfort. Originally intending
to operate their new load-shedding strategies under emergency situations only,
HP found that they could actually benefit from using them on a day-to-day
basis. Due to their conservation efforts over the past eight years, HP Roseville is currently
saving $1.5 million annually.
Enhanced automation allows HP to program a not-to-exceed
setpoint for electrical demand and instruct the EMS to initiate
pre- programmed load shedding strategies when that setpoint
is approached. The system is able to monitor the effects of
these strategies on overall demand throughout the day and to
make continual adjustments so that the demand is kept just
below the setpoint.
Direct control over mechanical HVAC equipment allows HP
to operate their systems efficiently. Facility operators can now
adjust zone temperatures based on actual, real-time occupancy
levels. For instance, if operators know that personnel in one
section of a building will be assembled in a conference room
for three hours on a summer afternoon, they can operate HVAC
equipment so that temperatures are higher in the emptied
building section and lower in the crowded conference room.

P’s enhanced automation project involved expanding the capabilities of existing
systems: A Siemens APOGEE
®
energy management system, a high-speed local area
network, direct digital controls (DDC), and Square-D PowerLogic
®
power monitors.
The modifications included mainly software programming of the EMS, along with
some new hardware and wiring. The result is a powerful building automation system
that can maintain demand setpoints without disrupting occupancy comfort.
To monitor the real-time effects of load-shedding strategies on overall demand, HP
linked its electric utility meters to the APOGEE system via existing Square-D
PowerLogic monitors that were attached to the meters. The system now collects and
archives 15-minute interval data. This linkage allows facility operators not only to see
the immediate effects of load-shedding strategies, but also to program their EMS to
reduce campus-wide demand to a specified kW amount. The EMS will now shed
loads in a pre-determined sequence until demand reaches the setpoint.
This pro-
gramming
was made
possible by
the addition
of both
automated demand control ventilation and lighting controls. To implement demand
control ventilation, CO
2
sensors were installed to ensure that air quality levels remain
above standard as outside air volume changes. The EMS was also programmed to send
digital signals to gradually close hundreds of variable-air-volume terminal boxes and
control valves to reduce the use of chilled water for space cooling. Chillers and pumps
in the central chiller plant respond to the reduced demand for chilled water as they
would to normal reductions in cooling demand. Variable frequency drives on chilled
water circulation pumps slow the pumps to reduce the circulation in the secondary
chilled water loop, and the load on the chillers is reduced until the chillers shut down.
HP’s lighting system was also enhanced with new controls. HP installed multiplexers
to lighting control panels in six campus buildings. The EMS is programmed to shut
off pre-determined, non-essential lights whenever load reduction is needed. Following
the curtailment, the EMS automatically returns lighting to normal levels.
