Solar analysis and shading
The solar radiation control incident on the building envelope is essential to contain the expenditure of energy related to the summer air conditioning. The uncontrolled entry of solar radiation causes surface overheating (and hence air volumes) in indoor rooms. The combination of this effect with that of the direct radiative exchange between surfaces and occupants, creates conditions of thermal discomfort that aggravate the discomfort already caused by the excessive heat input.
The solar analysis is technically accomplished on a virtual three-dimensional model of the aim of the study. On the same lines of an "integrated design", its first purpose is to suggest to the designer technical and architectural aids best suited to optimize free solar gains during the winter months and to shade the glass surfaces during the summer. Protect yourself from the sun that penetrates in July through a large window facing south is partially possible through technical parameters relating to glass (low solar influence or g factor), but definitely more effective providing architectural shielding, which are an opportunity for a peculiar morphological action of the building in question.
