PMV is an index that predicts the mean vote of a large group of people, represented as a 7-point thermal sensation scale. stringify ( new comfort . PMV equation underestimates thermal sensation by 13% in summer season and overestimates by 35% in winter season, for NV buildings whereas in case of HVAC buildings overestimation is found to be 31% and 33% in the summer and winter seasons respectively. The PMV is an index that predicts the mean value of the thermal sensation of a large group of people on a sensation scale expressed from (-3) to (+3) corresponding to the categories cold, cool, slightly cool, neutral, slightly warm, warm and hot. In order to comply with ASHRAE 55, the recommended thermal limit on the 7-point scale of PMV is between -0.5 and 0.5. Where CLO is the "Clothing level" and MET is the "Metabolic rate" you entered as input in the CBE thermal comfort tool, respectively. Environmental factors (such as humidity and sources of heat in the workplace) combine with personal factors (ie your clothing) and work-related factors (how physically demanding your work is) to influence your 'thermal comfort'. 2017.

Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD) . The calculation method is based upon the determination, through an iterative process, of the clothing external temperature, being the PMV index calculated from a human body thermal balance equation where internal heat generation . Results are calculated from the inputs of air temperature, mean radiant temperature, relative humidity, air velocity, clothing thermal resistance and metabolic rate. The PMV, ET*, and SET* indices have been designed for indoor use in accordance with the permanent environmental conditions of indoor spaces, whereas OUT_SET* and PET indices have been basically developed for calculation of the thermal comfort within outdoor environments [14]. Comfort (guessing you are using Fanger PMV-PPD comfort model) is related to 4 environmental parameter (air temperature, mean radian temperature, relative humidity, air velocity) and 2 subjective parameter (metabolic rate anf clothing thermal insulation), so comfort is not all on air temperature. You have to calculate the PMV and PPD levels for all conditioned zones of the building evaluated.
