am trying to model a large building with heating and no cooling. The heating
is constant volume. 90.1 Appendix G says I need to model the baseline system
as a VAV system with heating and cooling, and that I need to include the
baseline cooling system in the proposed building.<o:p></o:p></span></p>

700 does not allow “divorcing” the heating from the cooling, which
means I will end up with a VAV heating system. <o:p></o:p></span></p>

CDS is saying that this is what I have to do. I accept the need to have a
VAV cooling system, but being forced to have the heating as VAV means the energy
differences between the proposed heating and the 90.1 minimum heating system
will not be calculated since they are the same.<o:p></o:p></span></p>

question is, how do I model the heating system as constant volume and have the

with it?<o:p></o:p></span></p>
