For Glasgow case study, the plane has a length that allows the sun to come inside completely during winter and blocks the excess amount during summer.For the Palermo case study, the length of the device is increased in order to shade the glaze surface properly along the whole warm period, but it also helps the building to be warm in winter. For shading the west façade, a different solution was sought for both case studies. For shading the western façade in Glasgow, an overhang was introduced, shaped as a frame, that basically protects the door from bad weather. The same overhang was introduced for the entrance door as well. For Palermo, the amount of afternoon solar radiations during summer is quite abundant, hence a shading is necessary. As in the western façade there are doors leading to the kitchen space, the outside area could be linked with the interior and be used as a lunch/dinner/relax area for the occupants. To this end, shading this space was carefully planned with an external structure protecting the façade from direct radiations and a leisure outdoor area to enjoy. The structure is made by four pillars connected to each other throughout small rafters, and the structure is completed by vertical louvres. Throughout the simulation on SketchUp, the solution efficiency during later afternoon was evaluated to see if the device was efficiently protecting the building from lower solar radiations. |
