Hi,

What is the easiest way to model demand controlled ventilation and
static pressure reset in trace?

Jim,

Demand controlled ventilation can be modeled by simply using a schedule. Trace does have a way to do it another way, but using a schedule to reduce ventilation is the most straight forward.

Static pressure reset is simply based on the fan curve you use for the supply fan. Trace has two curves built in, and one is shown below as an example.

I am trying to model demand controlled ventilation as well.  For the proposed building, I created a ventilation schedule similar to the building's occupancy schedule.  What schedule do I use for the baseline building?  Available 100% or another ventilation schedule, like one from the ASHRAE 90.1 guidelines?
