<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>App G is fairly clear that the baseline EXTERIOR walls are
"lightweight," and metal-framed. Floors & walls are mentioned,
but referenced to exterior ENVELOPE constructions and U-factors. <o:p></o:p></span></font>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The U-M states the "baseline building is assumed to be
steel-framed," but then goes on to state "if the proposed building
has thermal mass in the EXTERIOR construction... then the mass is
credited."<o:p></o:p></span></font>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>So, if a proposed building has poured concrete frame and
floors, can/should the baseline building be modeled with "light
weight," "steel joist" interior floors? Or is this a
characteristic which is not specifically defined for the baseline, and thus the
baseline should be the same as the proposed?<o:p></o:p></span></font>
