Thermal comfort
Fanger model is a widespread approach for thermal comfort assessment. It is based on two indices: Predicted Mean Vote and Predicted Percentage of Dissatisfied.
-
PMV is an index predicitng the mean responseof a large froup of people, in a scale from -3 to +3
-
PPD gives a prediction of the percentage of thermally dissatified poeple
The evaluation of the PDD is quite simple as it only depends on the PMV. By contrast, the evaluation of the PMV can be laborious as it depends on many parameters such as the metabolic rate, the skin temperature and the clothing. Some of these parameters can be directaly determined from the norms such as ISO-7730. Other parameter such as the air temperature and pressure can be obtained by meausrement or by simulation. For more details on this subject, the reader can reffer to this page. An application based on sensors data of the IllKirch building, studied in the 4fastsim-ibat project, is presented by my colleagues Sarra and Hanane, see this page. Due to the short duration of the internship, this feature is not yet implement in the hygrothermal model. Work is in progress at Cemosis to adress this issue.
