[BLDG-SIM] Help calibrating eQuest building model

Seun,

Not knowing exactly what kind of system you are using, I can still try to make a few suggestions on what you can do to increase your heating energy.  Is your envelope modeled correctly...right insulation if there is any, windows, etc.?  Check your outside air numbers...increasing the cfm/person if needed can raise your heating energy.  As John mentioned, check your internal loads...maybe you are generating too much heat inside the building.  Check your heating schedule...is your setback temperature too low?

These are a few things to start with.  But you should post all of the details of your building (including location) and someone can help you figure it out.

Cheers,
Andrew

Subject: [BLDG-SIM] Help calibrating eQuest building model
 
Hello,

My name is Seun Odukomaiya. I am a graduate student at Purdue University
working on the Building Sciences. As part of my research, I am trying to
calibrate an eQuest model to match the energy performance of an actual
building for which i have data. Currently, I am having difficulties with the
electric heating element. The actual building (and thus the model) utilizes
an electric heating element. The energy data from the model, however, is
much lower than that of the actual building. I have tried several things,
but have been unsuccessful in increasing the energy consumption of the
electric heating element in my eQuest model. I need to increase the energy
consumption of the electric heating element in my eQuest model to get it to
match the data from the actual building. Any help in ways to accomplish this
within eQuest would be so greatly appreciated. Thank you in advance.
