The PMV (Predicted Mean Vote) was defined by Fanger (1972). It relates the (simple) energy balance of the human body to the thermal comfort of the person.
Normally the PMV value is used between -4 (very cold) and +4 (very hot), but as it is related to the energy balance it can also reach higher or lower values.
The PMV Model used in ENVI-met is a special adaptation to outdoor conditions made by Jendritzky/ DWD
(see http://www.dwd.de/services/gfmm/gfmm_kmm.html).

Why not ask the people living in your model world what they think about the design and the local climate?

Impossible?
