Climatic comfort

Help optimize thermal comfort of employees and passengers in workplaces and railway vehicles.

Tests objectives

  • Measure climatic parameters in the workplace and rail vehicles in order to determine the level of comfort felt by employees and passengers
  • Calculate PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) indices

 

Tests facilities

Temperature and relative humidity sensors

Testing norms

EN 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
