ABSTRACT
Indoor environment is a complex term, comprising the physical space of occupied areas in buildings or vehicles and habitation conditions. Assume that the best working and indoor conditions are provided in a comfortable indoor environment, having a favorable effect on inhabitants–dispatchers, maintenance, analytical staff (managers, designers, accountants, auditors, etc.), and regular inhabitants. The available optimal working conditions stimulate staff activity and productivity and decrease the number of operational errors, morbidity rate, and absence because of ill health.
