Project
Washington University, Retro-Commissioning Study
St. Louis, MO
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
