Choose of correct orientation save lot of energy, in middle east use of glass in south side must be minimized, please give feedback.

Building orientation can provide reductions to cooling loads through minimising solar penetration through windows, minimising solar absorption through walls and roofs, and by maximising cross ventilation.

The latitude and high insolation levels of the UAE lead to the highest intensity of solar radiation being on the east and west facing walls in summer and the south wall in winter. This promotes a strong preference for the north south orientation of main facades and glazing. Simple window shading is easy to facilitate as a result of the high solar altitude and greater reflection of solar radiation from the façade due to the lower angle of incidence.

The higher levels of humidity between the cooler months of December and March also require orientation to suit prevailing wind directions. Even if breezes are not perpendicular to a façade, oblique wind angles as low as 30°C to the wall face can be beneficial for cooling if coupled with cross ventilation to a leeward wall.

The main rule to optimize orientation in hot humid weather locate windows to North & South , avoid East & West windows, this makes heat gain through windows less

so i think this statement is not correct.

may be you mean the south west direction because this side is the maximum heat gain at summer between3 and4 PM.
