Underfloor Air Distribution

Underfloor Air Distribution (UFAD) can reduce energy costs up to 20% and improve ventilation effectiveness, indoor air quality and employee comfort. This solution has been shown to enhance productivity, decrease absenteeism and improve the building’s value – not to mention, it significantly contributes to LEED and WELL certification.

Maximize IAQ, energy efficiency and personal comfort

UFAD systems
UFAD systems use a raised floor to create an air distribution plenum to improve indoor environmental quality and modularity of design. UFAD uses stratified airflow to improve the ventilation effectiveness and indoor air quality of the interior space by delivering air at a low velocity through the raised floor directly into the occupied zone; allowing the air to naturally rise to a ceiling return, pulling contaminants and CO2 away from occupants.

UFAD systems can also improve flexibility and control. UFAD allows for easy diffuser reconfiguration in reaction to office occupancy and layout changes. Each diffuser can be equipped with personal comfort controls so that occupants can adjust the amount and direction of airflow in their space.

Aesthetically, UFAD eliminates the need for overhead ductwork allowing for exposed ceilings and reduces the amount of service distribution space, allowing for larger windows with greater daylighting and access to views.

To better incorporate strategic pressurization in workplaces to induce airflow that will lead to improved air quality, underfloor air displacement (UFAD) systems should be considered. These systems introduce clean supply air at the floor and accept return air at the ceiling, resulting in a once through pathway of airflow across the breathing zone of occupants before the air is returned to the central filtration system or exhausted directly out of the building.

Underfloor Power and Data Distribution

Enjoy the benefits of a low-cost and flexible power and data systems for the life of your building. With modular ‘plug & play’ power wiring and zone data cabling solutions, you can be assured your building will provide ultimate flexibility that can respond to organizational and technology changes quickly, easily, and cost effectively. A plug-and-play system allows you to add new equipment, address current office design trends, or make other moves, adds and changes very simply and quickly.

A Flexible & Sustainable Management System


Traditional power and data distribution is rigid and wasteful. Embedding power and low-voltage data cables in ceiling, walls and other structures limits flexibility by making change expensive and disruptive. Labor, material costs and down-time prohibit reconfiguring your space as your business needs change.

Reduced impact on base building

Access floors eliminate the need to embed power and data within concealed rigid structures, thereby allowing tenants the freedom to access services quickly and easily. Limitless access to these services provides the ultimate tenant flexibility. An architecture firm using open ceilings and an open plan layout on one floor can as easily be accommodated as a law firm with private office design on the next floor. 

Complete accessibility and unlimited capacity

An access floor provides you with access to your service pathway at any location on the floor plate, with finished floor heights that accommodate any capacity needs.

Tate products and sustainability

Tate products provide many sustainable advantages throughout the construction and operation of a building. During the construction phase, an Underfloor Service Distribution System allows a reduction in slab-to-slab height, decreasing the amount of required construction materials including eliminating ducts and reducing power and data cable lengths.

In operation, an underfloor HVAC system performs at a much lower pressure and warmer supply temperature than a traditional ducted overhead system, boosting indoor air quality, energy efficiency and personal comfort control. Lower system pressure helps improve energy efficiency through the reduction of mechanical equipment and longer economizer hours. Additionally, the ability to reuse service supply materials such as wires, cables, outlets and diffusers during reconfiguration further improves the lifetime sustainability of any facility.

Our customers enjoy sustainable and high-performance benefits by using Tate solutions in their buildings. Some of those benefits include:

  • Improved energy efficiency
  • Healthier indoor environmental quality
  • Reduction of material use
  • Design possibilities that allow for a more flexible and adaptable built environment
  • Reuse of service distribution materials during reconfiguration
Access floor and underfloor modular plug and play services allow for quick and easy equipment and technology changes at low cost with minimal disruption.
