Predicted mean vote equation
WebPredicted Mean Vote (PMV): is a scale used by your indoor climate engineer to predict comfort. Ideal range is between -0.5 and +0.5 (Neutral). Predicted Percentage Dissatisfied (PPD): If 85% of the occupants are satisfied (or 15% dissatisfied) with their thermal environments, then the Building/HVAC system is generally considered acceptable. WebMar 15, 2024 · Predicted Mean Vote (PMV) is the most widely used rational approach, which has been adopted by national and international standards, e.g., ASHARE 55 and ISO 7730 [ …
