  • I was sent to Marci Geller interview on Clam Radio, WUSB 90.1FM, 3-6-08 on the subject of: ASHRAE 90.1-2007 by a friend who told me last Wednesday you contradicted yourself so often it was hilarious but honestly, I can't see it. Can anyone else?

    45. 45. Goals for Standard 189.1 <ul><li>Establish mandatory criteria in all topic areas: - one “problem” with existing rating systems is that they contain few mandatory provisions - consequently, a designer can achieve “points” & claim that they have a “green building”, but still make no improvements in some areas </li></ul><ul><li>Provide simple compliance options: - another critique of existing rating systems is the need for extensive calculations (e.g. energy) </li></ul><ul><li>Complement green building rating programs: - Std 189.1 is not intended to compete with green building rating programs </li></ul>
