Under floor air distribution systems supply conditioned air to an occupied space via diffusers in a raised floor. This system effectively maintains thermal comfort and indoor air quality levels.

O+M Tips

• HVAC diffusers have a removable bucket trap that captures dirt and spills before they enter the underfloor space. Empty traps during normal custodial service.

End of Life Tips

• Usually reused by future occupants. If the mechanics fail consider recycling metal and plastic components.

For alignment with LEED Standards

• Optimize Energy: Comply with the HVAC and service water heating requirements, including equipment efficiency, economizers, ventilation, and ducts and dampers, in ANSI/ASHRAE/IES Standard 90.1–2010 Chapter 4, Design Strategies and Recommendations by Climate Zone, for the appropriate ASHRAE 50% Advanced Energy Design Guide and climate zone.
