Eastgate Centre, Harare
I was in Cairo a few years ago and in the old Islamic city there was a couple of big mosques. This dates back to the Islamic era (around 1359). Standing in the venue that separate the two mosques. Here is the location: https://goo.gl/maps/ibwqwb33PcUJvm1K7It was in the Summer and Cairo was boiling hot. But interestingly the venue was pretty cool. There was two factors: The mosques shadowed each other in a way that you don't get exposed in the sun. Another factor, there was a cool air flow coming from somewhere(?). My guess would be that the two buildings where engineered to both protect from the sun and generate the airflow.You can sit in the venue all day long and not be annoyed with the hot weather. The buildings themselves where pretty cool inside.I think the question is: Why are we so inefficient today? It's not about looks either: We are building even uglier buildings. The building I'm living in right now is buzzing with air-conditioning units. It's wasteful and it's also an inferior solution (headaches, dry air, only inside is cool, etc...)
