Chicago may not be winning any awards or making any lists for tall building construction right now, however the State of Illinois is making big leaps towards "green" building certification. Today, the US Green Building Council (USGBC) released its list of the top ten states with the most LEED-certified spaces per capita, and Illinois takes the number one spot. The ranking is a little confusing as other states like New York and California have more overall LEED certified buildings and space than Chicago, but since the list organizes city by most certified space per capita, Illinois takes the number one spot with its 171 projects at 24.5 million square feet of LEED space in 2013. Just a few weeks ago, Mayor Emanuel joined a coalition of other city leaders to fight waste from tall buildings, as they are the number one polluter in Chicago. Some of the notable LEED buildings the Chicago area brought on board in 2013 were Powell Elementary School, the llinois Holocaust Museum in Skokie, Lincoln Hall at the University of Illinois at Urbana-Champaign and of course the DePaul Theater School.
