Re: [EnergyPlus_Support] Net Energy Demand



Heating and cooling setpoint are usually of type duel setpoint with deadband and would be something like heatingsetpoint 21C and coolingsetpoint 23C. This avoids problems for heating and cooling simmultaniously. 

Outputting results for October only can be achieved in two ways:
1) simulation start and end times specified from 1 Oct to 31 Oct.
2) Create a schedule:compact with values returning 1 only for the month of October. Then reference this schedule's name as the last field in your output variable.

I don't get the sintax perfect from memory, but something like:
Schedule:Compact,
MyReportTime,
AnyValue,
Through, 30/09,
Untill, 24:00, 0,
Through, 31/10,
Untill, 24:00, 1,
Through, 31/12,
Untill, 24:00, 0;

Output:Variable, ZoneMeanAir Temperature, *, hourly, MyReportTime;

Hi, I'm trying to run a simulation in Open Studio with no HVAC system. My goal is to determine the net cooling and heating demand to maintain a thermal zone at 23 degrees Celsius for the month of October. 


Here's what I've done so far:


- In the sketch up application I've assigned the space a thermal zone and I have made it an ideal air load.

- In the open studio application I made a thermostat  for the heating & cooling set point to 23 degrees Celsius.

- For the materials, it is currently defaulted. 


Is this all that I need to do to get heating and cooling demand? My results doesn't seem to be correct as the heating demand is higher than the cooling demand for the month of October in California. 


As for the output variables I'm not which ones to pick... 


Also, how can I get hourly data for the month of October only?  


Please help!
