Figure 12: Room cooling plant sensible load calculation- base case (blue) and efficient case (red)
The above graph (Fig.12) obtained from the simulation shows a comparison in the room cooling
plant sensible load before and after applying the self-shading strategy to the building masses.
The reading for the base case is 111 KW, meanwhile its 68 KW in the efficient case .This indicates a
substantial drop in the amount of cooling required for the whole building reaching up to 38.7%.

Natural Ventilation:
The building receives and extracts the natural ventilation though windows which are designed
for the visual and the ventilation purposes. Cross ventilation is the main category that works in
the certain building envelope, flowing from the two side of the building, and this is continues
as long as the windows open; because of the pressure differences in both sides of the building
(Wood and Salib 2012).
