Defining solar power / solar heat flux

asked 2023-11-16 16:14:21 -0600

asli.kaya's avatar


I am trying to run a simulation where I want to define the solar heat flux into the system myself. I mean don't want Energyplus to add the contribution of solar power itself, I want to define it externally, as a q", maybe through the roof.

Is there a way where I can define the solar gain myself?

Thanks a lot!

There would be more than one way IMO. One option:

  • Select target surfaces, and set their Sun Exposure field to "NoSun"
  • Pick a layer in their referenced construction and make it an internal heat source.
  • Link the new layer to a low radiant heating system.
  • Calibrate as to achieve your equivalent solar power (q), e.g. intensity, schedule
  • Make sure to isolate and subtract the injected heat from your building electric use.
