A Case For Energy
Management
Facilitating Energy Efficiency
In A Government Building
By Steven W. Ford
Since the introduction of the
Energy Star program by the federal government's EPA
in 1992, the awareness and practice of energy efficiency
in buildings has increased dramatically. Initiatives
like the program's energy performance rating system
enable facility professionals to measure the efficiency
of their buildings in comparison to thousands of others.
The result has been innovation
on the part of facility professionals to achieve savings
and reduced environmental impact. Energy conservation
can be a form of reducing environmental impact by reducing
natural resources.
One commercial facility that
has exemplified energy conservation principles to the
maximum is The Joe Serna Jr. Cal/EPA Headquarters Building.
Located in downtown Sacramento, CA, the 25-story, 950,000-square
foot office building was completed in early 2001.
Ever since their involvement,
the building's managing company, has been dedicated
to making this large building energy efficient. The
building is operated by Los Angeles, CA-based Thomas
Properties Group (TPG). The managing company has implemented
a number of creative strategies to maximize energy efficiency
and create savings as well.
And because of its conservation
measures, the building earned the distinction of being
named the 2003-2004 winner of the BOMA International
Earth Award.
Cleaning Up Energy
As a result of the California
energy crisis of 2001, TPG began exploring new ways
to reduce energy usage immediately. It put together
a plan to have the janitorial staff clean mostly during
daylight hours, thereby reducing the amount of after
hour lighting needed.
In addition to the daylight
cleaning, the building is equipped with an energy management
system that allows staff to calculate and monitor energy
usage so data can be compared to prior months and years.
The energy conservation measures
began in February 2001 with average monthly usage at
775,933 Kilowatt hours (KWhs) and a daily average usage
of 25,247 KWhs. The 2001-2002 fiscal year showed a reduction
of 1.5 million KWhs in comparison to 2000-2001 consumption.
In January 2002, the rest of
the state caught up with TPG when California Governor
Gray Davis asked all state agencies to find ways to
reduce their energy consumption by 8%. Because of its
switch to daytime janitorial services, the Joe Serna
Jr. Building already reduced consumption by 8%, resulting
in a utility savings of $100,000 annually.
Not one to rest on its laurels,
TPG is currently working on a cost proposal to install
electrical metering per floor, which would allow for
floor-to-floor comparisons.
Other Measures
Energy saving products were
also used to create remarkable energy savings. A variety
of lighting controls, including ceiling-mounted photosensors,
office and desktop motion sensors, and high efficiency
(low mercury) lamps were installed along with high efficiency
glazing. Energy efficiency was further enhanced by strategic
cubicle/office placement to maximize the penetration
of natural light into the floor plates of each level.
Meters separated out energy
usage for lighting, HVAC, and plugs. A photovoltaic
panel array was placed on the mid-level rooftop, contributing
up to 55,000 KWhs of energy per year.
In partnership with the Sacramento
Municipal Utility District, the facility purchased 100%
green power.
TPG has also created an employee
merit program called Employee Achievement Rewards System
(E.A.R.S.) for contract employees, rewarding them for
energy saving ideas. The engineering department has
made such suggestions
as vending machine motion sensor devices and "intelligent"
lighting controls that may result in even greater energy
savings.
The facility has been identified
as an Energy Star building for two years running, with
a score of 96 out of 100. With this score, the building's
facility professionals make the claim that the Joe Serna
Jr. Cal/EPA Headquarters Building is the most efficient
high rise building in the nation. The
building also has aggressive initiatives in the areas
of waste minimization,
recycling, water conservation, and alternative transportation.
Should all buildings have as
many energy efficiency programs as the Joe Serna Jr.
building? In a perfect world, the answer is yes. But
facility professionals know that's not a realistic goal.
However, spreading the word about success stories such
as these can give facility professionals the inspiration
to adopt programs that work for the specific characteristics
of their buildings. The knowledge is out there, and
the biggest thing companies stand to lose are high energy
bills.
