For a floor to truly support a workspace, it has to do more than just sit there. As technology and tenants change, underfloor air distribution keeps the building fresh.
- Must begin with a collaborative design approach
- Better IAQ (Indoor Air Quality)
- Occupier Controlled Ventilation
- Adaptable and Flexible workspace
- Reduced Energy Consumption
Developers, building owners and architects face a complex challenge: build buildings that are not only pleasing aesthetically, but also are efficient, flexible and smart. Designers and builders must create structures that can be constructed economically, operate efficiently and be ready to change at a moment’s notice. Distributing air through the floor can go a long way toward accomplishing those objectives.
Popular in Europe and Japan for many years, underfloor air distribution is now making inroads in North America. As raised access floors become a preferred means of delivering voice, data and power, developers recognize the added value those floors can provide as a means of air distribution. Underfloor air technology can improve indoor environmental quality, reduce construction and operating costs, and boost productivity by giving occupants greater control over their environment and their comfort.
How is this different from what we are currently using?
Overhead mixing uses the concept of dilution. It never clears the air of the contaminates but rather dilutes them to an “acceptable” level.
Underfloor air on the other hand, through natural convection removes the contaminates from the breathing zone and has them settle in the displacement zone. It is then removed through the return air plenum.
The upper figure shows a beaker filled and emptied from the top, much like an overhead mixed ventilation system.
The lower figure shows a beaker filled with cool water from the bottom, with warm water exiting from the top.
