I am happy that LEED is accepting ISO 7730 and EN 15251 as alternative to ASHRAE 55. My problem is that there are no single requirements in these standards but examples / recommendations for design parameters for 3 different categories of comfort.
In IEQp1 we are requested to meet the minimum requirements for ventilation. I would assume this is true for IEQc7.1 as well, and choose the least category. Does anyone have experience with submitting this credit following ISO / EN?

Yes, we did it successfully using the ISO 7730 Appendix E and justifying by complete thermal simulation that PMV was never out of the interval -.5, +.5 for all rooms and all occupancy conditions.

@Serge Sidoroff
Is it really necessary to make a complete thermal simulation or can we make such a simulation for only one part per type of assignment?
I mean for an office building of 10 to 15 floors with the same open offices, is it necessary to make the simulation for each floor or just for one floor and considering that the result will apply to all floors that are identical?
Many thanks for your answer.
