The facades of buildings are designed with corresponding holes whose purpose is to contribute to building natural ventilation, illumination light from the outside and allow their users to see the same environment.
In return the entry of sunlight produces a temperature increase in the interiors of the building and the consequent increased use of air conditioners and fans, increasing power consumption.
Proper building design factors should be considered as its location, its climate and geography. These factors allow the adoption of bioclimatic strategies to achieve thermal comfort and light naturally.
Among the multiple strategies of bioclimatic architecture to reduce solar gain in summer is the use of sunscreens both indoors and outdoors. Choosing the most appropriate types of protection depends on the building site and orientation of each facade. For guidance
South recommend the use of fixed guards or semi such as roof eaves, horizontal flight
For guidance West Northeast and recommended the use of Mobile sunscreens vertical or horizontal slats phones.
For guidance This and West recommend the use of sunscreens mobile, it's nice in cold weather or warm sunlight inlet at dawn or dusk.
The following table shows different types of sunscreens and energy savings can be achieved with each of them:
