Sustainable school buildings

Have you been searching for a really good article on sustainable school building design?  One that addresses LEED standards but goes above any beyond?  I found a good one!  It actually was written in 2006 but it is still very much applicable today.  The article "Sustainable K-12 Schools" (found here) is written by the Leonardo Academy, based in Madison, WI.  

They note the following elements of sustainable design and operations that have direct effects on student performance:

• daylighting
• thermal comfort
• indoor air quality
• acoustics
