<p>While this is not a college program, your son might be interested in the [url=<a href=“http://www.usgbc.org%5DLEED%5B/url”>www.usgbc.org]LEED[/url</a>] rating systems, developed by the US Green Building Council to evaluate construction projects for “sustainability”. LEED addresses a wide variety of “green” construction and design issues, including credits for the use of “salvaged, refurbished, or reused materials”.</p>
<p>The LEED systems are well known in the architectural community. I would expect that sustainable design issues in general, and the LEED systems specifically, could be studied at most architecture schools.</p>
<p>The USGBC also sponsors “LEED Accredited Professional” certification for individuals; this title is now held by thousands of architects, engineers, etc. Unlike most professional certifications, the LEED-AP has no formal education or experience requirements, just a (rigorous) examination. So it is actually possible for a motivated individual to qualify as a LEED-AP while still in school, although this is rare in practice.</p>
