TII this study the influence of temperature of thesupplied air of a personalized ventilation systemon energy need has been investigated by meansof simulations with IDA-ICE software. GenOptsoftware was used to determine the optimalsupply air temperature. The simulated officeroom was located in a cold climate. The resultsreveal that the temperature of air supplied bypersonalized ventilation and its control strategyhave a marked influence on energyconsumption. The energy consumption wit11personalized ventilation may increasesubstantially (in the range: 61-268%) comparedto mixing ventilation alone if energy savingstrategies are not applied. The results show thatthe best supply strategy is to provide airconstantly at 20C, the minimum allowedsupply temperature. Energy savings (in therange: 32-47%) may be achieved withpersonalized veiltilatioil in comparisomi withmixing ventilation when the room temperatureis controlled between 18C and 29C.
