Fanger, P.O.

P.O. Fanger was an engineer and researcher who developed the concept of thermal comfort, primarily through the creation of the Predicted Mean Vote (PMV) model. This model predicts how comfortable most people will feel in a given indoor environment based on factors like temperature, humidity, air speed, clothing, and activity level. Essentially, Fanger’s work helps engineers design indoor spaces—like offices and homes—that promote comfort and well-being by understanding and controlling these environmental factors. His contributions are fundamental in HVAC (heating, ventilation, and air conditioning) system design to ensure occupant comfort.
