Abstract: It is disclosed a method and system for controllably adjusting temperature of a training area of an interactive training simulator performing an interactive computer simulation. The interactive training simulator, such as a flight simulator, is associated with a non-simulated area (NSA) housing electronic components used for performing the simulation. The heat generated in the NSA is transferred to the training area, or cockpit, hence eliminating the need for a heating system. Hence, the controlled recirculation of the hot air into the non-simulated area (NSA) improves efficiency of the interactive training simulator and reduces energy consumption. The system also maintains air quality inside the training area by continuously monitoring non-temperature related parameters such as humidity, or gas, volatile organic compounds (VOC) or particle concentrations.
