Simulation Study Analysis
Self- shading:
Below are generated images for the Suncast simulation showing the self-shading strategy applied in the building in both cases and measured in July 15th at 14:00. Values obtained for the
room surface 1 in the base case shows a total average of 70.2%, meanwhile in the efficient case it
reached up to 52.78%, and the variation is 24.8% indicates an improvement in the building shading property after inclining the south walls.

Simulations were carried out and the results are shown in the following table (Fig.11) for a selected
wall in the south part of the building to compare between them. In the base case, results show
that the wall is exposed to the sun in every month throughout the year, even in the summer
where the sun reaches the highest vertical angle, still the period from 11:00-14:00 in June and July
receiving a solar exposure. Meanwhile in the passive case (efficient case), the wall is totally shaded
from April to August.
