On the other hand, the entry of the sun's rays produces an increase in temperature in the interior spaces of the building and the consequent increase in the use of air conditioning equipment and fans, increasing the consumption of electrical energy.
A correct design of the building must consider as factors its location, its climate and geography. These factors allow the adoption of bioclimatic strategies to achieve greater thermal and light comfort in a natural way.
Among the multiple strategies of bioclimatic architecture to reduce solar gain in summer is the use of both indoor and outdoor sun protections. The choice of the most appropriate type of protection depends on the location of the building and the orientation of each of the facades.For the South orientation it is recommended to use fixed or semi-fixed protections such as roof eaves, horizontal flights
For the West and Northeast orientations, the use of mobile solar protections with vertical or horizontal mobile slats is recommended.
For the East and West orientations, the use of mobile sun protections is recommended, being pleasant in cold or temperate times the entry of sunlight at dawn or dusk.
