One has to wonder about the carbon footprint of 20,000 architects, engineers and builders flying off to a convention, but there is a lot to see and learn. This year the sustainable building event Greenbuild International Conference and Expo is back in Chicago, and speakers include TreeHugger founder Graham Hill, who will address the crowds on Thursday, November 18.
In this slideshow I show some of the things I have seen in the past, and some of the issues I am hoping to find new information about. It has been a difficult year for the U.S. Green Building Council (USGBC), overlord of both LEED and Greenbuild, and I think this show will be an interesting one.
Daylighting and Natural Light
There are a lot of high-tech methods of lighting, but the cheapest is always going to be daylight. Last year we saw skylights that tracked the sun with GPS
and solatubes that piped light into the interior of buildings.
