Green Building Seminar Presentation Yesterday I was one of four presenters at a Green Building Seminar. I gave a 30 minute presentation on my current project, the Dell Children's Medical Center of Central Texas. It was probably the first time I've given a presentation before that large of group - 100+ building professionals. Apparently I didn't mess it up too badly because I had several people give me favorable comments afterward.  ¶ 6:27 AM
