You Should Ask
Is the system strong enough to support my current equipment and any future equipment I may upgrade to?
The structural characteristics of the Tier E/A™ floor are unsurpassed. The product’s design, including the unique pyramid configuration created by cooperating floor panel support struts to create a truss system, makes the Tier E/A™ understructure the strongest you will find anywhere. The die cast aluminum floor panel is likewise remarkably strong, and its strength does not depend on any type of stringers, which would get in the way of easy access to the wires and cables housed in the System’s upper level.
The Standard and Heavy Duty panels are the same thickness so they can be interchanged throughout the room always maintaining an even surface.
Panels are made of Post Consumer Recycled Aluminum and are manufactured in the USA.
Will TIER E/A™ adapt to any future equipment and/or increased heat loads that I may encounter?
TIER E/A™ was designed to provide maximum flexibility by simply relocating airflow grates to any module where air is required. And, it does so without the use of costly and cumbersome containment devices. So long as you have the cooling equipment available to meet the heat loads of the equipment.
The video demonstrates the ventilation effectiveness of TIER E/A™, which can be accomplished anywhere in the room.

Can I reduce air conditioning energy consumption with TIER E/A™ ?
TIER E/A™ allows you to save energy and lots of it…
For over 40 years air delivery in computer rooms has relied on “precision” down-flow air handling units (AHUs) used in conjunction with cable-clogged, leaky, conventional raised floors. The fact that this doesn’t work is demonstrated by the universal plague of hot spots, cold spots, air handler short cycling, negative air flow (where cooled air actually flows back down under the floor through perforated panels) and the need for containment methods . These problems exist even though the typical data center design provides at least 25% more air conditioning than is actually required to meet the room’s heat load.
The Tier E/A™ system solves all of these problems, even in the demanding environment of critical (Tier I—IV) data centers. It does so by allowing the use of larger, more energy efficient cooling equipment sized to match the actual heat load. The A/C equipment can be located in a separate mechanical room, if desired, and still provided uniform, reliably pressurized air delivery to the entire data center space.
TIER E/A™ cost in comparison to a room using a single level raised floor?
How much does TIER E/A™ cost in comparison to a room using a single level raised floor?
It depends in-part on the kW density of the equipment because as the heat density increases you will need less of the TIER E/A™ product. The premium cost ranges from $36 down to $8 per sf as shown in the Table below.
* These numbers are based on a room with 100-24” X 48” Cabinets.
Of course, saving space translates directly into cost savings.
In addition to the smaller footprint made possible by the Tier E/A system, other savings come from reduced requirements for walls, ceilings, sprinklers, detectors, and finishes. Because the data center space can be smaller the overall building shell can be smaller as well. There are additional savings from reductions in things such as cable cutouts, extra redundant air conditioners, and the elimination of costly containment systems. These savings really add up, as reflected in the Table below.
* These numbers are based on a room with 100-24” X 48” Cabinets.
And, this doesn’t take into consideration savings from:
- Cable Trays
- Diesel Generator
- A/C Equipment
- Security Improvements
- Plenum Rated Cable
- Utility Credit
- MAC Savings
Do I still need to have CRAC units surrounding the perimeter and sometimes in the middle of the room?
Not only don’t you need CRAC units around the perimeter of the room, or installed through the middle of the room, you don’t need CRAC units in the room–period. For example in this picture you see there are no CRAC units installed in the room, they are behind the single wall far, far away from the opposite wall (140 feet). In fact we’ve shown that with Tier E/A it is possible to move air 160 feet from the unit discharging it, meaning you could build a 25,000 sf room with all the air coming from only one side of the room. This benefits security since all service and maintenance of the cooling equipment is performed outside the white space.
TIER E/A™ verses conventional floors or overhead?
What’s it like to install cables and wires in TIER E/A™ verses conventional floors or overhead?
Cables and wires are housed in the upper tier, where they are completely isolated from the air stream. They are always up off the floor and easy-to-reach. Working on them always takes place in the ambient room environment. Because the wires are separated from the air stream there’s no need for costly plenum rated cables, which saves a lot of money.
The system is stringerless regardless of finished floor height and, without compromising structural integrity, an unlimited number of panels can be removed for fast, safe wire installation;
Wires and cables are separated from each other in a variety of easy-to-install and easy-to-relocate modular cable trays. Overall it’s far safer and more flexible than using overhead cable tray.
There’s never a need to work off dangerous ladders, which is how 50% of all slips and falls occur.
Do I need more floor space or ceiling height?
The space planning analysis provided here was done based on hypothetical data center floor plans designed with 100 cabinets at a variety of different kW loads ranging from 5 to 30 kW in increments of 5 kW. The space planning was for 24” wide x 48” deep cabinets laid out in a hot aisle/cold aisle configuration. With Tier E/A™, cold aisles can remain narrower even as cabinet loads increase and AHUs can be housed in a separate mechanical equipment room. In the conventional design, Air Handlers cannot be housed in a separate mechanical equipment room because of the limitations that are inherent in distributing air under a single level floor. Air distribution engineering often permits lower ceiling heights with TIER E/A™,. and TIA-942 requires only a 6” spacing of cable trays when installed under the floor v. 12” when overhead.
Simple geometry was used in all instances to ensure a fair and equal evaluation. The Table shows impressive space savings for the designs using the Tier E/A™ system. These space savings are attributable to the system’s greatly enhanced air delivery efficiency, which is due to the greater static pressures made possible by the system’s unique construction.
Why should I use a raised floor?
Good room design is about layering services, however, without a raised floor overhead distribution of wires, cables and containment devices are required for the distribution of services. This means that the layering of services is disrupted by vertical zones that obstruct the effective distribution of services e.g., lighting, smoke detection, fire suppression, and security devices. Making reconfiguration a nightmare, moving the complex labyrinth of cable trays, and containment is a major overhaul, to the room, just to accommodate higher density equipment, or larger cabinets. Even if you can’t get all of the electrical services
TIER E/A™ is a fully integrated, layer design approach so all changes can be made without costly disruptions.
TIER E/A™ saves you a serious amount of trouble when it comes to making changes…
