Abstract
The authors have conducted the following research works in order to estimate evapotranspiration rate from evergreen shrub in analysis of urban thermal environment. Evergreen shrub is one of plants which are generally planted around buildings and on the roof of buildings. (1) An estimation model of evapotranspiration rate was developed by combining the JARVIS model with the calculation model of PAR distribution inside a shrub canopy. (2) Some parameters appearing in the estimation model were identified using experimental data on rhododendron pulchrum and rhododendron indicum, and then validation of the model including the identified parameters was carried out by comparison between estimated data and those obtained in an artificial climate room. (3) A simulation study was conducted using the developed model to find the best arrangement of shrub for evapotranspiration.
