Hi,

we're experiencing lots of difficulties to correctly assess this credit. Some notes:

- we're trying to guarantee compliance following option 1 (sDA and ASE simulations);

- we're using IESve for our simulations, since we already use it for energy simulations for a long time.

The majority of the buildings we need to assess, include large open-spaces (>1000 m2). When we try to simulate these spaces, we're getting lots of errors in the software and in fact we can't get any results for sDA parameter. We already cleared with the software provider that this is not an hardware issue, apparently is related with the algorithms used by the program. Given this, I ask:

- Has anyone suffered this issue with IES and solved it?

- Which alternative softwares would you recommend us to use to assess this requirement in large spaces?

Regards,
