The European Standard(EN 1264) and ASHRAE Handbook specify the design method of radiant floor panel, which are available for the design phase of radiant floor heating and cooling systems. The European Standard(EN 1264) and ASHRAE Handbook were studied for this paper. Considerations for application of radiant floor heating and cooling system design in Korea were deduced. Unlike the ASHRAE Handbook, EN 1264 specifies operation temperature as indoor design temperature to reflect effects of radiant heat transfer, which should be considered for control strategies and devices. Design dew-point temperature to prevent from surface condensations is one of the critical design conditions for cooling. Cautious determination of this dew-point temperature is required for hot and humid climate like Korea. Radiative and convective heat transfers are calculated separately in ASHRAE Handbook. On the other hand, they were integrated in EN 1264. The limit(maximum) thermal output that depends on the surface temperature and temperature drop should be calculated considering a domestic trend about these parameters.
