The changes caused to the environment have made the human beings to rethink about them attitudes towards nature. In view of the foregoing, the concept of Sustainable Development has being used in many situations. In the civil construction, this term may be applied through the proposal of buildings that properly interact with the climatic conditions of the surrounding environment and guarantee comfort to their residents. It this sense, this paper seeks to discuss about the ways of improving buildings’ sustainability from Brazilian semiarid, proposing solar shading devices to dwellings from Paulo Afonso – BA. Thus, according to the insulation geometry, it was designed different shading devices to protect the windows from direct sunlight during most of time. With this type of strategy, it is possible to improve the thermal comfort of the residents, as it allows to reduce the gains of heat from solar radiation. In view of this, according to the study of the geometry of the sunshine in the locality, it was suggested models of shading devices that protected the windows of direct solar radiation for the longest time possible. However, it was noted that this fact was not adequate in some occasions due to the occurrence of problems related to obstruction of visibility, lighting and natural ventilation. In view of this, it was suggested as a solution to block the insolation inside the buildings in the periods in which the highest temperatures in the region are observed. In the houses analyzed, the results showed that the shading devices reduced the thermal load by 40%. Furthermore, it was noticed that the rooms facing west are exposed to the worst thermal conditions due to they have the highest heat gains.
