Dear all, 1. Could you please tell me how did you get the values for radiant asymmetry of ceilings and walls, vertical air temp. difference and floor surface temperature for NC projects.

We are working on an art gallery project that has tight environmental requirements within the gallery spaces.

For an open-plan office space with individual working spaces the project team has used operable windows in order to provide thermal comfort control.

I'm wondering if anyone is capable of explaining to a layperson such as myself the difference between the ISO and the ASHRAE options for this credit.
