The term sustainable is frequently used in the literature on built environment. A practical approach commonly used on buildings that aims to be sustainable are the shading devices. However, that use must be planned knowing that the design decisions involve a range of consequences that are not restricted to conditions of direct radiation and thermal comfort, but they are also relate to other aspects such as levels of natural lighting, energy consumption, privacy and outside view. This paper aims to analyze the use of shading devices in buildings that are associated to the principles of sustainability and see how these elements contribute to its performance. A literature review about the concept of sustainability applied to buildings and the use of solar shading was done. Buildings from the “Solar Decathlon Europe 2012” that use brise-soleils or slabs as shading devices were analyzed to investigate the contribution of those elements for sustainability of buildings. The choice of buildings from that award is justified because that event brings together the latest in sustainable buildings and due to the availability of data for analysis. Aspects of sustainability related to brise-soleils were selected among those addressed in the literature review: thermal comfort (blocking of direct solar radiation and the possibility natural ventilation); visual comfort (lighting and views to outside); materials (durability and reuse); and energy efficiency.
