Physical Plant Helps Create Sustainable Campus
With the recent establishment of the Office of Sustainability, the University of Florida's commitment to conservation of
resources and campus sustainability has been strengthened and made more visible within the university community. However,
UF's efforts to create a more efficient campus have been ongoing for years, and Physical Plant has always been a vital and
important player in this process.
One of PPD's major contributions to campus sustainability has been our recycling program. Established in 1989, the program
has grown from a fledgling department with minimal responsibilities, to a fully-rounded program which handles disposal of almost
all the solid waste generated at the University.
Al Krause, PPD Solid Waste Coordinator, recalls: "Our recycling program was created as a response to the Solid Waste
Management Act of 1988, which established recycling goals for the state of Florida, and authorized state agencies to begin
spending monies on recycling efforts. At that time, the
University of Florida and President Criser decided that
even though it was not required by the act, UF would
establish our own in-house recycling program, and I
was hired as the coordinator of that program."
At first, the program was only responsible for col-
lection and recycling of soda cans and paper products.
SOther types of refuse, such as medical waste and con-
crete products, were handled by various departments
c across campus. But as the program grew, Krause saw

"In 1996, the program's title was officially changed
to the Office of Solid Waste Management," he said.
"Under our new title, we were able to consolidate mul-
tiple types of waste into the recycling program through
one office. This not only greatly improved our ability to
coordinate and fund the recycling program, but also to
implement more productive and efficient collection/dis-

recycling containers in nearly every office and class-
room. Types of refuse to be recycled include all paper products, concrete and masonry debris, yard trash, scrap metal, sludge,
used shipping pallets, beverage containers (glass, plastic and aluminum), and vehicle waste such as tires, antifreeze and motor oil.
The refuse is collected on campus by PPD and taken to local centers for processing.
Krause said, "So many things can be recycled these days we take old bricks and roof tiles and grind them up in a rock
crusher. Then they are used for things like athletic track surfaces and tinting sidewalks or asphalt. Old concrete and masonry, too,
is ground up and then re-used as drainage stone, or in rip-rap (a type of rock used to prevent erosion around riverbeds and stream

At the present time, Krause says, the Office of Solid Waste Management typically recycles around 40% of the total waste
stream generated at the University. But he maintains that number will increase to near 60% over the next five to ten years.
"I see a lot more re-use of products in the near future," he says. "I think we need a greater emphasis on purchasing more
durable products, and more products which can be easily recycled. I also think that our students and staff will be assuming a
greater individual responsibility, a greater emphasis on throwing your old cans and bottles in the proper recycling bins, and more
informed decisions on what we buy and how we dispose of it. That will go a long way toward increasing our recycling percentage
and increasing the sustainability of our campus."
"We're always looking for new recycling opportunities," he con-
tinued. "It's an evolving business across the country and I predict
exciting things in our future."

Another major component of Physical Plant's efforts to increase
sustainability at the University is our Energy Management Office.
Jeff Johnson has been the coordinator of this office for the last five
He says, "The Energy Management Office is responsible for
things such as making sure all our new buildings are energy efficient, -
installing new and more efficient lighting in offices and classrooms, -
and generally monitoring the consumption of campus utilities and
eliminating excessive use in that consumption. We try to eliminate
waste without affecting the comfort level of our students and staff."
One of Johnson's main goals has been to convert all fluorescent
bulbs on campus from the old T-12 style to a newer T-8 bulb design.
"The T-12 light uses a magnetic ballast," he said. "The T-8 uses an
electronic ballast, which is a lot better from an energy conservation
standpoint. The T-8 bulbs also have a higher flicker rate and give off PPD Energy Management Coordinator Jeff

says that the few which still use T-12s will be converted within the
near future. Along with the more efficient bulbs, Johnson makes sure that new buildings on campus follow codes which state that
they must have occupancy sensor light switches installed. These switches detect motion within rooms and shut themselves off
automatically if no motion is found within a certain period of time.
"It's not the kind of thing where you're going to be sitting in a room and the lights will turn off by themselves and leave you
in the dark," he says with a smile. "But the occupancy sensors will help cut down on wasted electricity with lights being left on
all night, or left on in unoccupied classrooms or public areas."
Another duty of the Energy Management Office is to set building automation schedules across campus. "Most of our
buildings have computers in the mechanical rooms which perform specific tasks," said Johnson. "For example, they might control
aspects of the building's mechanical system, such as the air handler controls or the temperature hot/cold set points. What we do
is monitor those automation schedules and tweak them to get maximum efficiency we can set the systems to operate at lower
levels when buildings are unoccupied, or during seasonal changes which might affect energy consumption."
Johnson said that he urges all staff and students to be conscientious of their energy consumption, and to do simple tasks
which can make abig difference. "Things like turning off the lights whenyou leave the office at night, turning off PCs and general
office equipment like printers and copiers, those can save us a lot of money in energy conservation. If you're a student and you're
the last to leave a classroom, turn off the lights. And if you spot instances of energy waste, for example parking lot lights which
are on during the day or outside doors to buildings that don't close properly, please report those to our Work Management Office
at 392-1121 and we'll work towards fixing them."
Finally, one of the oldest sustainability-based programs on campus is also one of the largest and most important. Physical
Plant's wastewater treatment program has been in effect at the University of Florida since 1948 the facility was first housed at
the comer of Lemerand Drive and Museum Road (now the site of the Physics Building), and was moved a few blocks south to the
new, state-of-the-art Water Reclamation Facility in 1994.
Utilities Superintendent Chuck Fender explains, "Here at the Water Reclamation Facility, we take the sewage generated on
campus and run it through a biochemical process called BioDenepho. This process generates microorganisms which consume the

waste material in the sewage. We then remove the microorganisms, leaving behind clean water."
This reclaimed water is used by Progress Energy's CoGen Plant in its production of steam, which is used in campus heating,
ventilation and air conditioning systems. Secondarily, the water is used to irrigate campus grounds and the University Golf
Course. Over 2 million gallons a day are purified in the Water Reclamation Facility.
"Basically, we take that water and squeeze every single bit of energy possible out of it that we can use for beneficial
purposes," says Fender. "We operate under very strict state regulations regarding the quality of the water we produce and our
processes. Everything is monitored very closely to ensure that our reclaimed water meets all standards for cleanliness."
The next ten years will see continued growth at the University of Florida, and PPD officials are already preparing plans for
handling that growth in the wastewater sector. "Our capacity at the facility is 3 million gallons," Fender says. "At our current
output of 2 million gallons a day and growing, we're looking at ways to expand our capacity to help carry the wastewater treatment
program into the future, and better meet the needs of our customers."
Weil Hall Chiller Expansion Project Begins
PPD's Architecture and Engineering Department recently oversaw the completion of the first phase of an ongoing project to
increase the cooling capacity of the Weil Hall chiller plant. The Weil plant distributes chilled water to the northeast corer of
campus, including Ben Hill Griffin Stadium, the O'Connell Center, and the Hub area.
Project Manager Milica Trindade explained, "This project is designed to upgrade the four chillers within the Weil plant from
1425 ton units to 1700 ton units, over a period of sevenyears. This increased capacity will allow the plant to handle the increased
load from new buildings coming online, such as the Women's Gym and Murfree Hall. It will also better equip the plant to handle
the increased load that will come from future new buildings and renovations in that area of campus."
Chillers are large, cylindrical machines which use refrigerant to produce chilled water. The chilled water is then piped into
buildings, where it flows through building air han-
dling unit coils. Fans blow air across these coils to
produce cooled air, and the cooled air is used to air
condition classrooms and offices.
"The chiller replacement project began at the
end of 2004, during the Christmas break," said
Trindade. "During that semester break period, we
were able to take the plant offline and remove all of
the plant chilled water piping before the Spring se-
S. : master resumed. The piping was replaced by larger
diameter pipe, to handle the increased flow from the
larger chillers. We took the opportunity to discon-
nect and remove the oldest chiller. In preparation for
"- the new chiller's arrival, we continued with the rest
Sof the mechanical work, such as upgrading one of
the cooling tower cells, replacing and adding new
pumps, and upgrading the supporting electrical
equipment. Completion of the first phase piping
project will enable us to have minimal chilled water
outages on the future chiller projects."
d t Maintenance Specialist Charlie Milford added
Workers use a crane to maneuver a 1700-ton capacity chiller
into its new home inside the Weil plant. The chiller is the first
the year, to take the plant offline. At that time the
of four replacement machines scheduled to be installed over
plant is operating at a very low output anyway, and
we shifted the load to the McCarty plant for the
duration of the downtime. Our chiller plants are all connected so that if we need to perform maintenance on one plant, the others
can take up the slack."
The new 1700-ton, two-stage Trane chiller, was brought inby flatbed truck at the end of March, 2005. "Before the chiller could
be connected, it received a corrosion-prevention coating to protect it against rust," said Trindade. "You don't want any standing
water to be able to create corrosive reactions with the metal, or you will lose chiller performance. After coating, final mechanical
and electrical connections were completed. Controls were programmed and contractors began testing the unit, which took until
fall 2005. Finally, the first of the planned four new chillers was brought online."
