font-family:Arial'>A quick, but kind of hazy question for me at least,
regarding LEED projects. Let's just say, that a building is composed of
multiple wall types, spanning a range of the ASHRAE 90.1 definitions...some
portions of the building is steel framed, another portion is mass wall, and yet
another portion is wood framed, for example. In this case, what would the
baseline be defined as? Does each wall remain categorically intact, and
you simply choose the baseline U-factor that corresponds to that wall type, or
do you have to determine the wall type that makes up the majority of the
proposed building, and choose this wall type as the baseline wall type? </span></font><o:p></o:p></p>
