<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Just
had this comment from a reviewer – the ASHRAE 90.1 handbook explains this
(it was page G-21 in the ASHRAE 90.1-2004 Handbook, but I don’t have the
2007 handbook to tell you that page number). For a semi-heated space, the
baseline building models only the heating portion of the system. For an
unconditioned space, the baseline has no system modeled (any energy use is a
penalty in the proposed model). Conditioned spaces must be modeled based
on the systems designed and the baseline system per Table G3.1.1B; however,
where a heating or cooling system is not designed the proposed model must use
the same system as the baseline respectively (heating or cooling).<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>The
semi-heated space heating system would need to comply with the baseline system
provisions for heating systems in Appendix G for the baseline model and the
proposed system would be modeled as it is designed.<o:p></o:p></span></p>
