<html><body bgcolor="#FFFFFF"><div>On a sort of related topic - was there ever an addenda that allowed you to use the Uvalue and SC for the NORTH walls instead of the Uall for all orientations. Just got called out on this for a recent project, but have used the North coefficients on at least 5 previous projects successfully... Trying to understand the LEED inconsistency. For that matter, why even have an entry on the EAc1 for the North orientation coefficients?<br><br></div><div><br>On May 12, 2009, at 2:20 PM, "Cramer Silkworth" <<a href="mailto:silkworth@transsolar.com">silkworth@transsolar.com</a>> wrote:<br><br></div><div></div><blockquote type="cite"><div>
