Residence Hall Complex
Mechanical design and construction phase services for a new
two-building housing complex with traditional-style double rooms and
community bathrooms housing approximately 350 students. Total square
footage is 113,000. Project facility has achieved a Gold rating
under the LEED green building program.

The complex utilizes a four pipe
hydronic HVAC system comprised of two water cooled chillers
with scroll compressors, a two cell open loop cooling tower
with ultra low sound fan blades, two 94% efficient copper
finned type natural gas boilers with sequencer panel, a
plate heat exchanger for waterside economizer, and fan coil
units. Each room or group space is served by one or
more fan coil units controlled by a wall mounted thermostat
located within that space.
Tempered recovery ventilators
located in internal mechanical rooms were used to directly
provide outside air at room neutral temperature to all
occupied spaces in the complex. These ventilators
contain enthalpy wheels that are used to pretreat the
outside air with building exhaust air to lower building
heating and utility costs.
The mechanical design and
equipment specification assisted in optimizing the
building’s energy performance 32% over a code minimum
The building automation system
monitors both the quantity of outside air delivered to the
building and the carbon dioxide concentration of densely
occupied areas to ensure design IAQ requirements are
Ultra low flow faucets and
shower heads were utilized to achieve 34% water savings over
the code minimum requirements set by 1992 EPACT standards.
