Cost: $32,000,000
Area: 162,000 GSF
LEED® Gold Certified
The project entailed the renovation of an existing 99,000 GSF with
a four-story building addition of 63,000 GSF. The design included an
atrium, lecture rooms, classrooms, a media center, and kitchen.
The mechanical design featured custom air handling units with fan
wall technology, VAV, chillers, cooling tower, hydronic heat, variable
speed pumping, atrium smoke control, complete plumbing systems, and
automatic fire sprinklers. The electric design included a new 13.2
kV looped primary feed, 480V upgrade, new emergency generator and building
power distribution, fire alarm system, voice data and A/V systems.
SBEC used CFD modeling of typical classrooms to analyze air flow patterns
and profile. Balancing and testing was utilized in existing units to
establish air flows and capacities and pressure testing of ductwork
was performed to determine integrity.
