Ross & Baruzzini provided retro-commissioning studies for three campus facilities with the goal of reducing energy consumption and improving operations associated with the existing building systems. This project included the following facilities:

Urbauer Hall - 64,000 sf laboratory and teaching facility, home to the Department of Mechanical Engineering & Materials Science, constructed in 1959 and remodeled multiple times since

Lopata Hall - 43,000 sf multi-purpose engineering complex, constructed in 1981 and remodeled multiple times since

Jolley Hall - 55,000 sf laboratory and teaching facility, home to the Department of Computer Science & Engineering, constructed in 1990 and recently remodeled in 2016

The following systems were reviewed as part of the retro-commissioning studies:

  • Dedicated outdoor air systems
  • Central air handling systems and all associated VAVs and duct distribution
  • Campus/building chilled water system including pumps, piping and campus loop interface
  • Campus/steam/hot water heating system including heat exchangers, pumps and piping
  • Computer and telecom room HVAC units
  • Fan-coil and unit ventilators
  • Exhaust systems - central and stand-alone
  • Building Automation System

Project results:

  • 3,400,000 kBtu savings estimated
  • 9 ECMs recommended
  • $46,500 in annual energy savings estimated
  • $272,000 total budget costs
