Abstract : The amount of radiation loss is different in the urban and rural environment, since all the energy exchanges are modified by the so-called microclimatic changes. As a consequence, the need for heating or cooling of the same building is not the same in both environments. On the other hand, this problem can be studied from the point of view of the thermal comfort with respect to open spaces: streets, squares and courtyards of the buildings and cities, since the presence of these elements modifies the inside condition of a building directly or indirectly the radiative losses from building components like roof and walls affect the thermal comfort of the inside environment by means of altering inside surface temperature. The exact mathematical expression of these losses is important to predict the inside temperature of a building. It is easy to study the radiation pattern, if the building is not surrounded by any building or tree. Otherwise it adds complication to the calculation of radiative loss. In this paper, the objective is to analyse the effect of radiative loss from the courtyard and outer wall envelope from the cooling point of view. In order to study these effects, an empirical relation has been developed. The detailed analytical expression has been carried out in this paper for Courtyard base (or roof), while the building is in a cluster.
