An article (quoting a study) suggests that people who work in LEED certified buildings miss fewer hours of work and are less stressed and less depressed than people who work in "conventional" (i.e., non-green) buildings. With an increase in LEED certified buildings in Normal, employee health and productivity should increase. And employers with businesses in those buildings have a good reason to require employees to work even longer hours and to work additional days: it will make them healthier and happier!
[The best line in the article is the reference to the "lame-stream media." Very appropriate.]
