<p class=MsoNormal><span style='color:#1F497D'>Hi Joey, according to ASHRAE
90.1-2007 and before if the proposed system is ventilation with heat, the
baseline system should be with cooling and selected by Table G3.1.1A. And the
virtual cooling system should be created in proposed model (identical to system
modeled in baseline).<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>You could see that it is not reasonable
to assume virtual cooling system in both proposed model and baseline, since
cooling demand is not in actual building performance. In the New ASHRAE

<p class=MsoNormal><span style='color:#1F497D'>Is the garage with air
conditioning system? I mean heating and cooling. If the garage is just with
mechanical ventilation, you should model it as design in the baseline model. If
the garage is with air conditioning system(and the heating source is also
same), however it still in an office building, I think the baseline system type
is the same as the office baseline.<o:p></o:p></span></p>

<p class=MsoNormal>Hi, everyone:<o:p></o:p></p>
<p class=MsoNormal>I have a question about the system type of APPENDIX
G3.1.1.<o:p></o:p></p>
<p class=MsoNormal>As the below requirement. Is that means for an office
building with a garage, the garage system in the baseline building can be the same
system type with the purposed building . if not, what’s the list for the
additional system?<o:p></o:p></p>
