Does anyone have a spreadsheet to calculate PMV-PPD for ASHRAE 55-2004?

For LEED 3.0 (2009) the wording is "Upload supporting documentation with PMV/PPD calculation, ASHRAE comfort tool results, and/or psychrometric comfort zone chart from Standard 55"
For LEED 2.2 you just had to provide a narrative, but 3.0 requires the actual results from the calculations. I may just have to buy ASHRAE's "Thermal Comfort Tool", I was just hoping there was something else available.

The ASRHAE comfort tool is very basic. Personally for compliance
purposes it is just as easy to plot these design conditions on a
psychrometric chart if you don't want to spend the money.

I uploaded a Psychrometric Chart that I created using a free program
called Climate Consultant.

There are some equations to calculate them. The psychrometric chart does not
help lot. I used to calculate PMV/PPD with my own VB 6. But there are a few
important PMV/PPD equations behind the VB6.0 from some references that I
forgot.

There is nothing to do with climate consultants, BTW.

Min is right. ASHRAE standard 55-2004 provided computer codes in the
appendix for PMV/PPD calculation. What you need to do is just converting
those codes into a tool that is convenient for yourself, like VB in Excel.
Of course few inputs are needed to run the computer codes, such as mean
radiant temperature which can be obtained from an empirical formula as a
function of air dry-bulb temperature, surrounding wall surface temperatures,
and air movement speed, if I remember correctly.

I found this link that is in excel sheet.

You need to figure out how to use it.

Min Yan may mean this article that explains the Psychrometric Spreadsheet
Published in ASHRAE Journal, (Vol. 48, January 2006)

Or try my mobile calculator if you don?t have many points to evaluate. Here: http://www.iesd.dmu.ac.uk/~yzhang/wiki/doku.php?id=software:mobile:pmv_calc
