Microperforations in 22@ [257]

This facade is designed to protect the building from the South, South-east where the solar incidence is much higher. The closure is a glass facade, allowing in light and illuminating the reception of the building, the stairwell and the vast majority of work-study classrooms. The microperforated plate regulates the entrance of light.This facade uses a metal framed structure to hold the glass. On each floor we find a half-meter small footbridge that facilitates the cleaning of the facade.

<p><span lang="CA">The sun protection is composed of double metal uprights welded to the facade, where oval shaped&nbsp; lamellae and microperforated horizontal steel are held.<br /></span>The arrengement of the lamellae has been designed in order to give an optical sensation of movement at the facade.<br />The lamellae are not able to move. They are all fixed to a metallic structure and their inclination have been specially calculated.<br />Each one has been mounted with an inclination but never varying more than 30 degrees and it is not possible to change it unless you remove the lamellae.</p>
<p><span lang="EN-US">This solar protection allows the semidirect passage of light into the building at certain times protecting from the hottest solar hours. The space between the glass and the protection creates a small air chamber that helps to refrigerate the glass to function as a corridor.</span></p><p><span lang="EN-US">This protection fulfills its role well in this building, providing protection during the hours of maximum solar radiation and at the same time allowing a large amount of light to enter.</span><span lang="EN-US">As a point of improvement we</span><span lang="EN-US">believe that the facade should not be all glass, but in some strategic points should have a direct opaque facade or tinted glass that further regulates the entry of direct light, as we found certain computer rooms and areas would have been much better with a more accurate control of sunlight</span></p>
