Thermal comfort

Different indices have been created to measure thermal comfort of the occupants of the building. On this page, two of them are explained : Predicted Mean Vote and Predicted Percentage of Dissatisfied.

The second one (PDD) depends only on the first one (PMV), but the problem of the first one is that it depends on a lot of parameters which we can’t get from the captors installed in the building in Illkirch studied in the 4fastsim-ibat project : for example, the mean radiant temperature can be calculated either by using a globe thermometer or using the temperature of the different surfaces of the room.
