Studying the effect of adding a ventilation system consisting of two devices, impinging and personal ventilation, and knowing the extent of their impact on the presence of different thermal loads represented by humans, computers, and light inside a thermally isolated office room by using sandwich panels. In addition, examining the air distribution inside a room also found the required thermal comfort for two people who were represented in the form of the thermal manikin and inside them a heat source close to 80 watts, which is close to the heat emitted by the human being according to the global A share. The most important results that were obtained first when adding the personal ventilation system to the impinging ventilation showed a clear improvement in heat levels close to the thermal manikin at a level of 1.1 meters and above. Second, the homogeneity of temperatures within the space, where the difference between the main source of ventilation (impinging) and the heat at the level of 1.8 meters is relatively small, compared to the use of the impinging ventilation system alone. The aim of the research is to prove the efficiency of such a system within the Iraqi summer weather between march to June month, under the conditions studied during this project, energy savings can be achieved using this strategy. Providing respiratory and thermal comfort inside the air-conditioned space, especially in the people’s seating area at 1.1 meters, and achieving two goals of sustainable development (an industry with innovation and clean with affordable energy).
