Radiant cooled floors have been successfully used on many projects over the past ten years, and many ASHRAE and other peer-reviewed papers have been written on these projects. However, many questions still arise regarding the performance of radiant cooled floors when subjected to solar radiation. The convective cooling performance of a cooled floor has been reported by Olesen (1994) and Simmonds (1994); Borressen (1994) reported on the solar absorption of a radiant cooled floor, which was further reported by Simmonds, Gaw, Holst and Reuss (2000). Even with this research, many questions are still being raised regarding the performance of a radiant cooled floor when absorbing solar radiation. This paper explains the performance of the floor, including some limitations of the presented calculation method and information on controllability.
