Markus, thanks again.
Since the English is not my mother tonge, sometimes I'm geting confused by enterpreting some explanation although I'm already 37 years in the HVAC branch. Like for instance in Table G3.1.1-3 of 90.1-2013 - I'm wondering what was the meaning when distiguishing Public assembly and Nonresidential building type, because it might appear that my project belongs to System 3. And things like that....
Thanks and best regards.
