Hi all,<br><br>I'd like to get a better sense of how much more stringent Standard 90.1 has<br>become with each iteration. My (hearsay?) understanding was that a building<br>under 1999 required about 8% lower energy consumption to meet the standard
<br>than 1989.  And I've heard the 2010 version is going to be 30% lower than<br>2001. Are these figures correct, and can anyone tell me how 01/04/07 fit in?<br><br>Thanks,<br>Shaun Martin<br>email <a href="mailto:smartin@shaunmartinconsulting.com">
