Hi, I edited a weather file(.epw) using the elements software and the following error appears when I tried loading it back into Design-Builder.

"Error Reading header" and the weather file could not be loaded. Can you guide me with this issue?

Hey,

I would like to understand few warnings in the simulations under error file.

Can someone let me know do I add the "Output : Diagnostic" to the idf editor and is it possible to integrate it in the Design builder.

Hello,

We are modelling earth tube for a project and we would like to know is it possible to visualize the velocity of the air passing through the tube.

With volume flow rate and the radius of the pipe it is possible to guess the velocity But, we need to know the how the velo city is simulated to debug few errors.

Because I believe increasing the size of the tube reduces the velocity of the air for a constant supply which in turn supplies much colder/heated air then smaller radius with increased velocity.

Hey Team,

We are working with the Earth tube system as the major source of air intake into the building. But, I believe the earth tube works as a standalone system in the E+.

Is it possible to integrate it with the Heat recovery, before supplying the air into the zones ?

Please take a look at the attachment for the reference.

Hi,

I'm running an energy simulation in design builder and i received the following error.

* Severe * DayltgAveInteriorReflectance: Multiplier > 1.0 for window SERRECDE:SERRECDE_WALL_1_0_0_0_0_26_WIN in Zone=SERRECDE:SERRECDE

Can you please guide on how to find this particular surface from my model either in design builder or in other application.

Thank you Ag. It is working now, but I'm curious to know how can be find the specific wall in the design builder that is
