This is a general comment I made on ASHRAE 189 as part of a review committee. ASHRAE 189 is (by its own admission) an attempt to make LEED into code language so that it can become law. While I have reservations about the LEED standard and its failure thus far to produce good results in energy savings, I am more strongly opposed to 189 because, by virtue of being a code, it resorts to enforceable prescriptive measures that are too often inappropriate.
