Although the prevailing wind direction is SSW, the wind direction on the frst and second foors is south. This demonstrates that the original wind direction may be unimportant, because the wind direction within the devel¬opment is shaped by the houses. Of course, this case uses a wind direction that deviates only slightly from the south (no more than 30o). Hf the wind was from the southwest, the scenario could be very different.
