Project No. 07K3E
Agency:
Department of Health and Family Services
Institution:
Southern Wisconsin Center
Request:
Request authority to construct a project to replace the air handling and air conditioning
units serving the lower east wing of Wallace Hall and the Learning Resource Center in
the Graham Food Service Building at Southern Wisconsin Center for an estimated total
project cost of $389,000 General Funds Supported Borrowing (GFSB) Facility
Maintenance and Repair, and to permit the Division of State Facilities to adjust the
individual project budgets indicated below.

Southern Wisconsin Center – Wallace Hall - $189,400
Project Description:
Project will remove six (6) existing, small, vertical style air handling units in the ground
floor mechanical room and replace them with one larger air handling unit rated at
approximately 13,000 cubic feet per minute (cfm) or approximately 35 tons of cooling
capacity. The existing units provide air to the lower floor of the east wing. The new air
handling unit will be connected to the existing air distribution ductwork. Additional air
ductwork may be required to maintain proper air balancing. The project will also
connect the new chilled water coil(s) to the new campus-wide chilled water system
currently existing elsewhere in the building, making it more energy efficient.
Project Justification:
Wallace Hall was constructed in the early 1960s as an infirmary. The existing air
handling units and refrigeration unit are 40 years old, no longer function as designed,
and are difficult to maintain. While a preventive maintenance schedule has been
maintained on these air handling units, malfunctions are high, including leaks on both
the refrigerant and water sides of the units. Parts for these units are no longer
manufactured and are difficult or impossible to locate. In addition, the units were
designed to serve the building when it was a hospital and used more outside air than is
necessary for the current occupancy of the building. The current usage includes office
space for human resources, payroll, administrative services, facilities maintenance
supervisory staff, etc. By replacing the original units, this will allow us to reduce the
capacity of the units, thus reducing the overall energy usage and operating costs, a
target that is in line with the Governor’s initiative for Conserve Wisconsin, a statewide
energy reduction program. Finally, the new campus-wide chilled water system that the
replaced air handlers will be connected to is significantly more energy efficient than the
original refrigeration unit.
Southern Wisconsin Center – Learning Resource Center - $199,600
Project Description:
Project will remove and reinstall one (1) 16,000 cubic feet per minute (cfm) air handling
unit equipped with steam heat and chilled water coils, dampers, louvers and a new fan.
The project will also require some ductwork modification. This project will require
extending the chilled water lines from the adjacent Building No. 7, also known as
Central Building, so the unit can use the excess refrigeration capacity of that unit,
thereby resulting in energy savings.
Project Justification:
The Learning Resource Center (LRC) is a multi-functional space in the Graham Food
Service building. This space has been air conditioned since the building was
constructed in 1969. The original air handler was designed to control the environment
that was once used for a large employee and patient dining area. Today, we need the
air handlers to control the environment for classroom-style and conference room
spaces, as well as accommodating computer equipment that need to dissipate the
resultant heat. Currently, the LRC is primarily used to train new Resident Care
Technicians and other staff at the Southern Wisconsin Center for people with
developmental disabilities. This space is also used for large meetings and gatherings
and is open to any of the campus occupants including DOC and DVA. The LRC also
houses the institution’s computer training laboratory.
Even with routine and preventive maintenance, the existing refrigeration equipment and
air handling units are beginning to fail. Dampers no longer seal, thus allowing outside
air infiltration. This results in cold air coming in to the building in the winter and warm air
coming into the building in the summer. Fan shafts are worn and under cut, causing
misalignment and vibration. A year ago, the compressor failed and required
replacement. The original equipment vendors are no longer in business and parts are
no longer available. Due to the high occupant densities this space was designed to
accommodate, maintaining a functioning HVAC system to control the temperature in
warmer weather is necessary for this space to serve its intended function. Connecting
this cooling load to the chilled water system in the adjacent building will result in
significant energy savings.
