Defining Thermal Comfort
What is a good thermal comfort?
How to evaluate the thermal comfort
Introduction to the Standards ISO 7726 and ISO 7730
ISO 7726, Ergonomics of the thermal environment — Instruments for measuring physical quantities for measurements according to ISO 7730.
ISO 7730 – Ergonomics of the thermal environment — Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria
Measuring thermal comfort according to the standard ISO 7730
Key input parameters
4 Environmental variables:
- Air temperature
- Air velocity
- Air humidity
- Mean radiant temperature – measured values
2 Personal variables:
- Metabolic values – Personal activity level
- Clothing insulation – Individual selection
Key output parameters:
- OT – Operative temperature
- PMV – Predicted Mean Value
- PPD – Predicted Percentage of Dissatisfied
