Abstract

In this study, with the aim of collecting the quantitative knowledge about radiant heat controlled by trees, the experiment was conducted using the ICAL radiant panel that can reproduce the radiant heating of constant intensity. By using this experiment, we considered the correlation of the shape of the tree and the shielding effect of the radiant heat of trees. As a result, shielding effect of radiant heat by camellia was confirmed by experiments. That effect was especially observed to have large tendency near the trees. Transmittance of heat flux and the shielding ratio(1-φy) have almost the same value, it was confirmed by the correlation of transmittance of heat flux and the shielding ratio(1-φy). Therefore, trees shielding ratio is one simple indicator that assesses the incident of heat shielding effect of the trees.
