Combining flooring and air systems for modular, energy-smart, and comfortable commercial interiors.
What is UFAD?
Underfloor Air Distribution (UFAD) is an HVAC delivery method that supplies conditioned air through a plenum beneath a raised floor. Air rises naturally from floor-level diffusers, creating an efficient vertical thermal gradient that cools occupants while reducing energy waste near ceilings.
Benefits of UFAD with Raised Floors
- Energy Efficiency: Less fan energy is required due to lower static pressure, and cooling is targeted at the occupied zone only.
- Flexibility: Easy reconfiguration of workspaces and diffusers in office and data center environments.
- Improved Indoor Air Quality: Air is supplied directly into the occupied zone, reducing recirculation of contaminants.
- Integrated Services: Power, data, and HVAC run beneath the floor—ideal for modern modular design needs.
Structural Integration Considerations
- Floor Height: Minimum raised floor height should be 300–450 mm to accommodate ducts and cabling along with airflow.
- Plenum Airtightness: Gaps between tiles and around service penetrations must be sealed to maintain air pressure and prevent leakage.
- Load-Bearing Panels: Use high-strength floor panels rated for office or equipment loads, especially in server rooms or collaborative spaces.
- Diffuser Placement: Must align with occupant zones and heat sources (e.g., under desks, near windows).
Design and Zoning Tips
- Zone Air Control: Use modular VAV (Variable Air Volume) boxes for zone-level temperature control.
- Return Air Path: Ensure ceiling-based return vents or open plenum returns for proper air circulation.
- Raised Access Floor Layout: Coordinate early with MEP teams to ensure diffuser positions, cabling routes, and service tiles are optimally aligned.
Case Study: Corporate Fit-Out in Kerala
In a recent project in Kochi Tech Park, a raised access floor with UFAD was installed in a software development office. Air diffusers were installed at user workstations, with cabling and power supplies routed below. The result was a 22% reduction in energy consumption and improved user comfort scores.
