Hello.

I'm working on a project in Italy and evaluating to buy a new BIM software.

Is there anyone who knows if it's possible to analyze our building with a proper BIM SW?

Energy Model AND LEED Excel sheet required

Hi

Summary from Appendix G:

- self-shading is not allowed to be modeled in the baseline

- manual shading devices are not required to be modeled in the baseline
