Abstract

We verified the property of an effective radiant temperature based on direct radiation using an effective radiant temperature based on multiple radiations. The difference between two formulae was within ±1 ℃ when short-wave reflectance of buildings' surface was less than 4 ℃ and the temperature difference between building surface and ground surface was within 5 ℃. The ratio of atmospheric radiation to long-wave radiation from the ground was newly defined as long-wave radiation property. Expression of linearized radiative heat transfer between the human body and outdoor environment was defined using the property.
