The energy efficiency implications of radiant floor heating is relatively well documented, but neither LEED nor the ASHRAE 90.1-1999 Standard appear to define how credit is provided within the energy performance simulation. In the July 2002 issue of the ASHRAE Journal, Bjarne W. Olesen provides research information on the effectiveness of radiant floor heating systems in his article "Radiant Floor Heating in Theory and Practice." In his work, Dr. Olesen indicates that a "5 K (9
