We very quickly just from that one little diagram we can start to see really dramatically which parts of the building are getting hit with the sun and which ones aren't. Now again, this may not seem like that big a deal to you if all the projects you've ever done are all set in stone because this is where the urban setting and this is the front wall, and the front wall needs to look like the buildings next door or something, but this is actually a dramatically important question in terms of energy use, in terms of how much air conditioning is used in these buildings, how much heat is needed in these buildings, how much day light we can capture versus having to use artificial light.
