PROJECT DESCRIPTION
The University of Nebraska at Omaha (UNO) Milo Bail Student Center first opened its doors in 1960 and has undergone multiple additions and renovations over the years. Alvine Engineering provided MEP services for the 1996 addition and was retained to help again with this architectural addition/renovation and building systems upgrade.

PROJECT HIGHLIGHTS

The project includes the following upgrades for energy efficiency:

• Replacement of the existing constant volume HVAC systems with variable volume air flow systems.
• Combined air handler zones and reduced the number from 12 to six, which reduced total fan energy and maintenance costs.
• Replacement of existing ductwork with new sealed and pressure-tested ductwork eliminated energy loss through existing unsealed ductwork air leakage.
• Lighting occupancy sensors were utilized to reduce air flow in unoccupied spaces.
• CO2 sensors in high occupancy spaces reduce outdoor air flow when spaces are unoccupied or at a lower occupancy level.
• Temperature sensors in the new exhaust hoods operate makeup air and exhaust fans when cooking is occurring. This approach eliminates constant system operation and prevents the system from being left on overnight.
• New digital temperature control system throughout the space provides enhanced control of HVAC systems.
• LED lighting throughout the renovated areas reduces energy usage and maintenance costs.
• Occupancy sensors shut off lighting whenever space is unoccupied.
• Daylight harvesting in the atrium reduces light level when ambient light is adequate.
