Hi,
I have the annual hourly mean radiant temperature results (from the energy model simulation). I'm wondering what MRT you have used in the past if you have all of these figures? How do you choose the MRT figure when you have all this data available for the entire year?
Thanks,

You probably have more info than you need to document the credit. ASHRAE 55 uses the "operative temperature", which is a combination of air temperature, mean radiant temperature (MRT) and other factors. Unless you've got a space with a MET rate above 2.0, showing that air temperature and humidity stay within the comfort zone is usually sufficient to document the credit.
