University
of Florida continues its commitment to sustainability
with the completion of the Mary Ann Harn-Cofrin Pavilion,
which is LEED-certified by the U.S. Green Building Council.
A two-story addition to the Harn Museum of Art, the pavilion
includes 6,780 sf of kitchen, cafe, classroom, office
and support space on the first floor and 9,400 sf of exhibit
space on the second floor. A second-story connector links
the exhibit space to the adjacent museum.
The primary efficiency measures included an improved building
envelope (both walls and glazing) over the minimum ASHRAE
90.1; reduced lighting and added lighting controls; a
highly efficient boiler system, and variable air volume
air handling units. Harn Pavilion is approximately 40%
more efficient than the minimum requirements and is well
above Florida’s energy code requirements. In water
use reduction, two credit points were awarded as a result
of reducing potable water usage by 39% below the standard
established by the 1992 Energy Policy Act. Waterless urinals
and sensor-operated, low-flow faucets and toilets provide
an annual savings of 657,000 gallons of potable water.
The key to the efficient HVAC design was to provide two
dual-path air handling units to serve two different zones.
Both units were provided with variable frequency drives
for maximum energy savings. The first air handler serves
areas with constant occupant density. In order to comply
with energy saving principles the motorized damper for
outside air intake is interlocked with kitchen hood exhaust
for control of outside air demand. The second air handler
serves areas with variable occupant density and features
a CO2 sensor to control outside air demand. Lighting efficiency
was achieved through a combination of general purpose
fluorescent strip lights, recessed compact fluorescent
down-lights, wall-mounted architectural fixtures, and
low-profile under-cabinet lights.
Other sustainable strategies include:
•Permanent entryway exhaust systems to capture dirt
and particulates.
•77.91% of the construction material was obtained
from sources located less than 500 miles away, thus reducing
the environmental impact of long-distance transport
•11.74% of the building materials were recycled
•Energy efficient dimmer controls in the lighting
in the exhibit spaces.
•HVAC and refrigeration equipment designed to reduce
emission of ozone-depleting CFCs.
•Temperature and humidity monitoring systems configured
to allow control over thermal comfort, including humidification.
•High-efficiency fans and motors in the HVAC systems.
