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?
