Calculations Required?

I think it's misleading that the RG says the "no calculations" are required. Clearly a bunch of calculations and numerical analysis are required.

I am still confused about how much documentation is needed for this credit. The template states, "Upload supporting documentation with PMV/PPD calculation, ASHRAE 55 comfort tool results, and/or psychometric comfort zone chart from Standard 55." Is the PMV/PPD calculation enough or are we required to upload one of the other two also? The "and/or" makes it unclear. I'm not sure what kind of results you can get from the ASHRAE 55 comfort tool and I really don't want to spend $117 to find out that I could get the same results on my own. Can anyone give me a description of the input required and the output obtained from this tool? And is it absolutely required for this credit?

Not completely sure about the comfort tool - I don't use it personally.

Depending on climate you may want to submit psychometric charts, to show how humidity control is being accomplished, especially at part load conditions.

I think, if you can show:
1) what the comfort zone is for your space type and use,
2) the range of thermal and humidity conditions, how they are achieved, and that they match the comfort zone,
and 3) that the air distribution has been designed so that excess air movement is not a factor,
then you should be all set.

The comfort tool might help if you have an unusual space type, or are attempting to show adaptive thermal comfort, but is probably more than is needed for typical occupancies.

The ASHRAE Comfort Tool was created in 1997 and is made for a Windows 95 Operating system. It is not compatible with 32 or 64 bit machines (xp, vista, windows 7...etc.). It also pre-dates the standard 55-2004 document and so compliance is questionable.
