FAQs about IEQc7.1 :

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).

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

Does anyone know if is OK to adhere to ASHRAE 55-2013 instead of ASHRAE 55-2004? Thanks!

LEED Interpretation #10416 allows ASHRAE Standard 55-2013 to be used for both LEED 2009 and LEED v4. I'm in Canada, and there is a similar interpretation (CIR #859) that allows LEED Canada projects to adopt more recent versions of ASHRAE standards and applicable addenda for any credit.
