[Equest-users] Can you use eQuest for PMV calculations?

[CleanTech Analytics]

I use both Energy Plus and eQuest, and try to choose between the two for
features not preference.

Energy Plus can produce many comfort calculations, including PMV, eQuest
can not.

I spent a moment and went through an Energy Plus file I am working on and
copied most of the possible variations of comfort objects, and published
them to this google spreadsheet:

Hope this helps, and if you decide to use and need some help with Energy
Plus please let me know.
