Sun Shading Catalogue. Adequate Shading: Sizing Overhangs and Fins

In hot tropical climates, it is necessary to eliminate the penetration of solar radiation into buildings through glazed surfaces through strategies such as appropriate building orientation (along the east – west axis), adequate sizing of openings (window to wall ratio), proper location of openings (facing north and south), careful selection of glazing properties and appropriate solar protection using sun shading devices. This document illustrates how to properly size shading devices for windows on different orientation in different latitudes at selected cut-off times.
