Underfloor Air Technology is "a method of delivering space conditioning in offices and other commercial buildings that is increasingly being considered as a serious alternative to conventional ceiling-based air distribution systems." The Center for the Built Environment at the University of California, Berkeley conducts research on this form of air conditioning to determine its advantages. There is an in-depth analysis given on the Web site that explains what the technology is, how it is applied, and where it has been implemented. A glossary and list of frequently asked questions are very helpful for people new to the subject, and there are also many details such as code requirements and construction issues for the more experienced visitor.
