FAQs about IEQc7.1 :

There are a few spaces in my project that can’t meet these requirements. Can’t I just exclude them?

ASHRAE-55 comfort criteria ask for space air speed. Is this the same as the supply air volume measured in cubic feet per minute (CFM)?


What should I do about a warehouse space?

How can thermal conditions for areas with metabolic rates outside of 1.0–1.3 be determined? (Per ASHRAE Standard 55-2004 Section 5.2.1.1, Figure 5.2.1.1 can be used for areas with metabolic rates between 1.0 and 1.3).

NC-2009 IEQc7.1:Thermal Comfort—Design

Open office with Displacement ventilation and Chilled beams

Hi there, I'm working on a office project with Chilled beams and Displacement ventilation. We are planning to do CFD simulations to analyse radiant temperature asymmetry , drafts vertical air temperature difference, etc. Would this be enough to document compliance with this credit? Regards, Santiago.

The CFD will show temperature and air speed, but you also need to show that those conditions fall in the comfort zone based on activity and clothing expected.
