<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'>Hello, I would like to model commercial building HVAC operation and
especially power demand at a 2-10 second time-step. I read about ESP-r on
eere.energy.gov (US) that: “Building and flow simulations can be undertaken at
frequencies of one minute to one hour and system simulations can be from
fractions of a second to an hour.” Does this mean power demand data can be
output/recorded as fast as every 2-10 seconds?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'>Also, can thermostat setpoint adjustments be made dynamically while the
simulation is running in response to changing building conditions? Or can many
10second (duration) simulations be strung together and automated with dynamic
thermostat setpoints implemented in between, according to predetermined logic
and evolving building conditions? <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span lang=EN-US style='font-size:
11.0pt'>I read on ESP-r’s capabilities page that modules can be driven by
scripts to automate tasks. Could you please elaborate on that functionality in
regards to the potential for modeling a building with dynamic thermostat
setpoint adjustments every 2-10 seconds, or at least every minute?<o:p></o:p></span></font></p>
