WTA provided engineering design for the HVAC replacement and new central plant for the historic Sheldon Concert Hall. Project features include:

• New 100-ton air cooled chiller installed on grade between the concert hall and the annex
• New chilled water pumps installed in a mechanical room on the annex and piping was routed to the concert hall air-handling units
• New hot water boiler and pumps installed in the new mechanical room and piping was routed from the mechanical room to the new air-handling units in the concert hall
• Two new low-pressure single zone air-handling units installed in the crawl space/basement below the seating area of the concert hall. The new air handlings were ducted through the crawl space to floor mounted air devices in the seating area of the concert hall to provide displacement ventilation. Double wall ductwork was installed for the first 20 feet of supply and return from the unit discharge to help control any noise from the air handling equipment.
• New low-pressure single zone air-handling units for the ballroom. These units, located in the attic of the ballroom, also have double-wall ductwork for noise control. Air distribution is through linear slot air devices in the sidewalls.
