In order to reduce the load to the earth environment, it is necessary to utilize natural energy. In this study, from this point of view, it has been investigated the utility of a fresh air load reduction system by using underground double floor space for air-conditioning in buildings experimentally and numerically. It concludes that the annual amount of energy saving by using this system is more than the energy loss caused by introducing it. Additionally, the computational results with the simple heat diffusion equation agree with the measurements. Therefore, it is clear that this system is very useful and the proposed model can use for the thermal design of it.
