[Trace-users] trane trace

[Fareed Syed]

Hello All,

 

I am new into the field of energy modeling. I am doing documentation on
my master's project on energy modeling of our office building.

 

I kindly request for giving me some notes on energy modeling and thermal
storage related to TRACE and in general.

 

Regards,

For cooling: I usually  use a setpoint between 72F and 78F depending on
the spaces served with a driftpoint of 85F.

For heating: I usually use a setpoing between 68F and 72F depending on
the spaces served with a driftpoint of 65F.

For unconditioned spaces I use a very high cooling set point (95F or
higher) and a very low heating set points (35F or lower....depending on
your weather location) so that the software won't generate any (or very
minimal) loads for these spaces.

 

I don't believe ASHRAE App G has any specific thermostat set point
requirements.  You just need to use something reasonable and they have
to be the same in proposed and baseline models.  A possible exception to
this would be if you are using different thermostat setpoints to
simulate the reduced energy associated with an unusual systesm such as a
displacement ventilation system or radiant cooling or something.  There
may be some archived info on that approach in the bldg-sim archives.

 

Hope that helps.

hi,

 

i have a question about setting "driftpoints" in the trace program.  i
am doing a base case VS actual design scenario model and i was wondering
what anyone normally uses as cooling/heating dry bulb temps and
thermostat driftpoints when they are modeling a scenario based on simple
ASHRAE guidelines.
