This paper analysis the impact of the location of sensors on their ability to provide information about the temperature distribution in a given space. Only temperature was investigated since it is the crucial parameter in estimating thermal comfort. The results from the research conducted in a lecturing hall revealed that one sensor currently operating is insufficient to map the temperature variability and thereby ensure the required thermal comfort conditions in the whole space. Analysis performed for four various scenarios and three sensors shows that optimal layouts and locations of sensors vary significantly from the current set-up. In the heating scenario it was possible to reduce the mean absolute percentage error (MAPE) of temperature estimation from 14.07% to 6.22%. In the remaining scenarios the observed improvement was not as spectacular but provided important conclusions.
