Tristan, thanks for creating this forum! I hope fellow Canadian users will share their experiences to build on the information already available in the other US forums. I just posted this on the NC 2009 IEQc7.1 page, but I'd like to hear from others on Canadian projects. Is ASHRAE 55-2010 (and therefore the ASHRAE Thermal Comfort Tool v2) acceptable in place of 55-2004? Only 55-2004 is referenced (with no addenda) for v1.0, while 2009 allows addenda to be used if applied for all credits. Technically, 55-2010 is a compilation of all 2004 addenda so I think it is acceptable. I'd appreciate feedback from others to verify or refute my assumptions. Thanks!
Hi Lindsay,
We have been using 55-2004 for all of our LEED2009 projects. Mainly because it is exactly what's referenced in the reference guide. I cannot speak for CaGBC, but I would bet that they would require a CIR to use 55-2010 in conjunction with ASHRAE Thermal Comfort Tool v2.
Looking at the current CIRs on the website, there is nothing mentioned about 55-2010. Also, if you can find a CIR on USGBC that would be a good indicator if this is an OK method. However, the CaGBC will most likely ask for a CIR of their own.
