consider precedent (CIR’s) a justification for anything… Any
project’s LEED review team is fully permitted to completely change their
stances between projects as they deem fit to make their case-by-case re-interpretations.
Is my world-view overly bleak, or is it advisable to caution others to take any
CIR’s with a <s>grain</s> block of salt these days?<o:p></o:p></span></p>
