Individually controlled local heating

For workers sharing the same office, there is normally a need for slightly different temperatures to fit their own optimal thermal comfort. In a laboratory experiment with thermal manikin, local radiant heaters have been placed behind office chair , providing heat at their backs, shoulders and necks .
The heat loss from the whole body or from specific body segments was measured during the experiment. The system proved efficiency for keeping the heat balance of the body and reducing the sensation of draught.
