I've been to the Eastgate Centre a couple of times and think it's an excellent building -- aside from its passive cooling, its retail space is quite people-friendly and attractive. That said, it's probably worth noting that Harare is not a particularly hot city, courtesy of its altitude (1500m/5000ft.) I wonder if this would be as effective in a truly oppressively hot place like the Horn of Africa.
