Example of Thermal Calculation ?

Eric, I just posted several sample documents for this credit (including ASHRAE 55 calcs and the LEED Online form, filled out) to the Documentation Toolkit for this credit (see the tab above). Thanks for asking!

Hi Tristan, I looked at your sample documentation above and have a good idea on how to proceed with documentation. My problem is that I am not using the same program. I am using ASHRAE THERMAL COMFORT TOOL V2. I will proceed the way you did on the documentation. However, for the ASHRAE THERMAL COMFORT TOOL V2, there is a tab called the MRT (mean root temperature). The inputs here are room dimensions, 1 occupant, temperatures ect. My question is, how would I proceed to document the MRT? Do I document it on a room by room basis, or do I document it as one building. If I document it on a room by room basis, then I would have multiple cutouts of the MRT calculator to upload, which I would not want to do.

John, The thermal comfort parameters are documented for each space type. I work on LEED Canada projects, but it looks like the documentation requirements are similar for LEED Online. I use a spreadsheet to track my input values (room dimensions, surface temperatures, air speeds, etc) as well as the MRT and PMV-PPD results from the ASHRAE thermal comfort tool. I include all of the parameters noted in ASHRAE 55-2004 Addendum "e". I select a representative room to analyze for each space type, and also any additional rooms with unique conditions (such as high glazing % or radiant floor slab). I then copy the summary info into the LEED submission table, and include my spreadsheet as supporting documentation. Hope this helps.
