Recently, i am working for a complex commercial project including a ice rink and a ski centre.
These two spaces are acturally very special, whether we can exclude them when we consider thermal comfort ?
Thanks!

Leanne, to my knowledge there is no exclusions in the credit, even though ASHRAE 55 has definite limits. So if the space falls outside of ASHRAE, then you must demonstrate comfort in some other way, either by standard of care, studies that might substantiate conditions, or something else. You might find some industry standard that addresses what the standard of comfort is. However, this is not a sure thing at all.
But short answer is no, you cannot exclude any space to get the credit.

Maybe use this and build a custom ensemble with very high CLO ( thick jacket, long johns, etc.) http://smap.cbe.berkeley.edu/comforttool

I think with high CLO and high MET you can be comfortable even in cold areas. This tool might help make the case to the LEED reviewers but it only goes down to dry bulb temperatures of 10 degrees C/ 50 degrees F. http://smap.cbe.berkeley.edu/comforttool A mechanical engineer can probably get more into the logic behind all that. Definitely provide a written explanation of your strategy with your preliminary LEED design submittal. We've had to provide a lot of back up data on our projects with Natatoriums because of the unique space conditions.
