Visual comfort and energy savings are results of the proper daylighting planning of spaces. As a first step to achieve these objectives we should be aware of the possibility of solar radiation access in the visible range of facades. This paper develops a descriptive morphological analysis of the urban, building, pass through component, and solar control system variables that determine access to visible radiation of a facade, considering regional variables. Its main objectives are: (a) to determine urban and building morphological caracteristics that affect access to visible solar radiation of front façades; and (b) to establish a diagnosis about the current state of these elements on front facades in the analyzed areas. This research work determines the importance of a detailed study of the front facade of buildings, given that 75% of the buildings analyzed have their central axis disposed perpendicularly to the front facade, 90% have no side retreats and 95% have a block building disposition. Likewise, it indicates that that there is no relationship between the use of openings and the solar control elements according to the regional clear sky climate.
