Hi everyone!

I use an existing PMV calculation in OpenStudio (written script from a user), which lets user insert a work efficiency schedule, a clothing insulation schedule and air velocity schedule. For the final calculation, this measure takes automatically inputs from air and radiant temperature and air humidity. I found out that calculation is also affected by occupancy schedule and activity level schedule (existing in space tab). The problem is that I cant find out how all these affect PMV calculation, reading the ruby script. Except from this, I need to skip calculation when occupants are off. For this purpose, I tried to set occupancy schedule to zero in specific timesteps, but in that case PMV turns negative (in warm days), which is completely wrong. Any help for this calculation would be useful.

Thanks a lot!
