Tate & LEED
A Tate access floor system and the advanced service distribution technologies it affords can contribute toward achievement of numerous credits for LEED-NC certification.
When all the components of Tate’s Building Technology Platform® Solution are utilized - the access floor, underfloor air and cabling, and PosiTile® carpet - they greatly contribute to the LEED Scorecard of a project striving for certification. The Tate solution can help to achieve prerequisites and accumulate points in the following categories and credit areas of LEED-NC Version 2.2.

Energy & Atmosphere
EA Prerequisite 2
Minimum Energy Performance
Underfloor air delivery (UFAD) systems used in conjunction with access floors reduce energy use below the energy consumption of comparative overhead systems by (1) reducing the amount of fanpower required, (2) using higher-temperature supply air for cooling, (3) using a greater amount of "free" outside air for cooling and (4) delivering conditioned air to occupants rather than to the entire volume of space.
EA Credit 1
Optimize Energy Performance 1
1. Fan Power Savings
2. Higher Air Supply Temperature for Cooling
3. Free Cool Air from Outside
4. Reduced Air Volume Requirement

Materials & Resources (MR)
MR Credit 1.3
Building Reuse
A Tate floor will last the lifetime of a building and accommodate a variety of future occupant requirements. Although an access floor will not help a LEED-NC project to achieve Building Reuse credits immediately, it can significantly help to do so later in the building’s life. Walls on access floors are easy to detach and erect elsewhere (walls are attached to floors by framing fasteners). In-floor air diffusers and electrical boxes are moved by simply relocating the floor panels that they are mounted in. Additional floor panels and understructure components can be purchased to complete new occupant fit-out requirements.
MR Credit 3.1 & 3.2
Materials Reuse
Access floor panels, pedestals and stringers can be uninstalled in their original locations and be reused in other buildings. Be aware that just as with the Building Reuse credit, the materials reuse strategy will not likely help to achieve LEED-NC points immediately. Rather, it is a long term sustainability strategy that an access floor can contribute towards in the long-term.
MR Credit 4.1 & 4.2
Recycled Content
MR Credit 4.1 & 4.2 Recycled Content
The typical Tate floor system used in commercial offices contains 46.8% recycled material consisting of 14.2% post-consumer and 32.6% pre-consumer content. All office floor systems and data center systems manufactured by Tate Access Floors contain recycled content in excess of the 20% (post-consumer + 1/2 pre-consumer) credit requirement.
MR Credit 5.1 & 5.2
Regional Materials
Tate access floor systems are manufactured entirely in York County, Pennsylvania. The steel used for panels and understructure components is recovered/manufactured in Sparrows Point, Maryland and Delta, Ohio. To view our location on a map, click here.
MR Credit 7

Indoor Environmental Quality (EQ)
EQ Prerequisite 1
By using an UFAD system in conjunction with a Tate access floor, the volumes of fresh air delivered to the breathing level of occupied spaces will easily comply with the minimum ventilation requirements of the IAQ prerequisite and the ASHRAE Standard.
EQ Credit 2
Increased Ventilation
A Variable Air Volume UFAD system may alone qualify the building for the Increased Ventilation credit. The key to exceeding the ASHRAE rate by 30% is to provide higher rates of outdoor air to the breathing level of the occupied spaces. A variable air volume UFAD system does exactly that it delivers fresh air from below directly to occupants’ six-foot breathing zone. As the fresh air enters the zone it replaces existing contaminated air (rather than diluting it). Pollutants and stale air in the zone are carried to the ceiling by natural convection, where they are removed through return outlets.
EQ Credit 4.1
Low-Emitting Materials: Adhesives & Sealants
The Tate floor system utilizes adhesives for adhering pedestals to the building floor which are in compliance with South Coast Air Quality Management District Rule #1168.
AIM 382 Pedestal Adhesive -- LEED-NC V2.2 Credit Compliance 35KB PDF
Seal Bond 95 Pedestal Adhesive -- LEED-NC V2.2 Credit Compliance 30KB PDF
EQ Credit 4.3
Low-Emitting Materials: Carpet Systems
PosiTile carpet tiles manufactured for Tate floor panels are installed without fieldapplied adhesive, ensuring compliance with the required VOC limit of 50 g/L. Each carpet tile is held in place by positioning buttons on its underside which fit into holes in the floor panel. Carpet tile and adhesive product data verifying compliance with credit requirements are available from PosiTile carpet suppliers.
EQ Credit 6.2
Controllability of Systems
By locating diffusers in an access floor, occupants gain control over volume and direction of airflow. Since this LEED point is so difficult to achieve without the use of an UFAD system, the LEED-NC V2.2 Reference Guide actually suggests using floor diffusers as a potential technology/strategy toward achieving this credit. Providing adjustable floor air diffusers to serve just 50% of regular occupants contributes toward achieving this credit. And further, occupant control is easily maintained when layouts change because floor panels with diffusers are easily relocated.
EQ Credit 7.1 & 7.2
Thermal Comfort
Thermal comfort is enhanced by several major benefits of UFAD:
Daylight & Views
An obvious strategy to maximize daylight and views is to increase window area and height. Integration of access floors with UFAD and underfloor cable distribution facilitates this by reducing the ceiling cavity space allocated for supply ductwork and cables, thereby allowing the ceiling to be raised and window heights to increase without increasing building's height. For each building level with an access floor and UFAD system, as much as one foot of space between floor floors can be gained by eliminating two feet in the ceiling cavity and allocating just one foot for an access floor.
