Best Practices

Tropicana Field

• Enhanced management and operational controls with their Building Automation System
• Computer now automatically controls all fans based on temperature and humidity
• System previously ran at either 100% or was off. Now it can run at 50%

MetLife Stadium

• Focused on improving operational controls and systems to maximize energy efficiency, such as controls for:
• Lighting (stadium and parking lots)
• Condenser water system
• Air handling units 

Target Field

• Maximized the Building Automation System
• Replaced lighting systems with LED or fluorescents
• Re-commissioned HVAC systems
• Implemented a “winterization” mode to shut off unnecessary equipment during the off-season.

Nationals Park

• Close monitoring via energy management system during non-game days and in unoccupied spaces
• Regular analysis of utility bills
