Fanger PMV — Predicted Mean Vote (Thermal Comfort)
A thermal-comfort model that evaluates and predicts how large groups of people experience the climate of an indoor space.
What is Fanger PMV?
The Fanger PMV model is rooted in human body heat-balance equations, tracking thermal-energy exchange between skin and surrounding air. It maps that balance to a standardised thermal-sensation scale and derives the Predicted Percentage of Dissatisfied (PPD) occupants. It is standardised under ISO 7730 and ASHRAE Standard 55.
When to use Fanger PMV
Apply when auditing indoor climate comfort, designing HVAC systems, or managing thermal stress in closed factory floors, control rooms, or offices.

What Fanger PMV assesses
The body segments and task variables evaluated in a Fanger PMV assessment.
What it assesses — six variables
- Air temperature and mean radiant temperature
- Relative humidity and air velocity
- Worker metabolic rate (activity level)
- Clothing insulation value
Scoring and action levels
Final score range: PMV index (−3 … +3) → PPD
Developed by: Ole Fanger, 1970s (ISO 7730 / ASHRAE 55)

Fanger PMV is part of our validated method roadmap. Our engine adds new methods on shared infrastructure — when Fanger PMVgoes live it will run from the same on-device capture and certified-ergonomist review as our live methods. In the meantime, tell us your environment and we'll map the live methods that fit today.
