Vertical Shading Device
While walking in Olaiyah Street, I was surprised that the Environmental Architecture (Sustainable Architecture) takes place in Riyadh! So, I couldn't stand watching without taking shots :D
Location: Olaiyah Street, Olaiya Town, Riyadh, Saudi Arabia
Function: It's used as a low energy architecture to decrease the solar radiation in hot cities like Riyadh in which the average temperature at day is 43°C - 45°C. so the shades and shadows are valuable there. I just wanted to know if the curtain wall and shading device could be cheaper than the other heat insulation materials?? I wish but I don't think so!
Just it's disadvantages that at winter solar radiation is needed since the winter there is very cold and very short, so it needs some balance.
