mean that the system must provide ventilation air while occupied? If that’s
the case then the fans would never turn off during occupied hours and then
would cycle with the load during unoccupied hours. <o:p></o:p></span></p>

don’t see a requirement anywhere in Appendix G for the baseline and proposed to
have the same fan system, so I believe when it states that the same cooling
system is to be modeled in the baseline and proposed they mean just the cooling
coil and heat rejection device.<o:p></o:p></span></p>

<p style='margin-bottom:12.0pt'><tt><span style='font-size:10.0pt'>Robby - the
fans must cycle with occupancy, and then when the space is not occupied the
must cycle with load. They can not cycle with load only. For Mike Kennedy's
system he would need to model the baseline with VAV heating and cooling. And
also model the same system in the proposed, however you could set the heating
coil capacities to zero, not create a heating plant, or not assign any systems
to the heating plant for the VAV system. (This is if you are using Trace 700).</span></tt><br>
