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 coming to Ergocure.ai
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.
Fanger PMV — frequently asked questions
What is 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 a good Fanger PMV score?
PMV index (−3 … +3) → PPD. A score of −0.5 to +0.5 is comfortable — ppd < 10% — target zone — while Beyond ±1 is discomfort and means thermal intervention required.
When should you use Fanger PMV?
Apply when auditing indoor climate comfort, designing HVAC systems, or managing thermal stress in closed factory floors, control rooms, or offices.
How does Ergocure score Fanger PMV?
Fanger PMV is on the Ergocure roadmap. Today the same workflow runs on our live methods — AI scores posture from a phone capture and a certified ergonomist validates every result.
Who developed Fanger PMV?
Fanger PMV was developed by Ole Fanger, 1970s (ISO 7730 / ASHRAE 55). Fanger, P.O. (1970). Thermal Comfort: Analysis and Applications in Environmental Engineering. McGraw-Hill. (ISO 7730; ASHRAE 55.)
