I’ve got an eQUEST model where my designed building has PIUs. I was
getting a number of hours of unmet loads till I turned on Night cycle
control. With PIUs you can set it to Zone fans only – which makes sense.
The loads were met and the energy usage went up marginally. <br>
<br>
The base building is a standard VAV system (system 7). Since the
VAV system doesn’t have zone fans, I have to set it to cycle on any. The
energy use goes up considerably in this case. Is this normal? Should I be
meeting the loads in another way?<br>
<br>
Also – is it acceptable to have night cycling for a LEED/Appendix G
submittal? The building is just not meeting its heating needs if I don’t
do this. It’s a historic building with a lot of perimeter glass (single
pane) and so the perimeter zones get pretty cold at night (one of the
reasons we have PIUs) <br>
<br>
Am I correct in taking credit for this?<br>
