EP Glass Material Error

#1

I’m trying to use HB EP Glass Material Component to create an external Film for the window. The Energy Simulation gives a Fatal Error.

  1. The simulation has not run correctly because of this severe error:
    ** Severe ** CheckAndSetConstructionProperties: Error in window construction E304 WINDOW WITH EX1–

  2. The simulation has failed because of this fatal error:
    ** Fatal ** GetSurfaceData: Errors discovered, program terminates.

Why is the material not accepted?

Hi @MansiDhanuka,
Is there really no air gap between the two panes of glass? Adding that might work.

Hi @devang

I was trying to add a tinted film to the glass and modeled it without any airspace. Is there another way to model films? Or if you know a way to calculate effective U-value of Glass and film together that I can plug into the EP Window Material component.

Thank you

Yeah. You can calculate that value using Windows. One of the tools from LBNL I am sure you know about.

Okay I will try that thank you.
