The radiative effects of building groups on single structures

The role of building group configuration in controlling the heating and cooling abilities of structures is considered. A computer model is described which simulates the thermal stresses of simple building groups composed of identical structures. The natural heating of the structures is measured as a function of the daily exposure of individual structures to direct sunlight. The cooling of structures is measured as a function of their sky view factor. Building groups are compared in terms of these measures at different latitudes and times of the year. The results show that group design can have a significant impact on the thermal stresses experienced by individual buildings.
