Hello to all,

I have an European project and I will follow Option 2. But I have difficulties in understanding the Method.

For mechanically conditioned spaces do I use ISO 7730 -2005 and for natural ventilated spaces to I use EN 15251 -2007?

Or shall I combine the ISO 7730 and the EN 15251 in every case?

The examples in the reference guide didn't help me a lot. Do you know where I could find more examples?

Thank you
