The study investigates the influence of indigenous tree species on indoor latent cooling loads in Ahmedabad, India, having a hot and dry climate. Focusing on ten mature tree species, and its phenological characteristics the impact on the indoor latent cooling load is analysed for a defined volumetric space under steady-state conditions. The analysis is based on nine representative conditions derived from the Indian Model for Adaptive Comfort (IMAC) for air-conditioned spaces, considering average dry bulb temperature and relative humidity.
