Analytical model for double skin roofs

In the current study, an analytical model is proposed that describes the thermal behavior of a heat discharge system in roofs. To validate it, an experimental prototype is used which has been tested by exposure to the sun and the measured results compared with the predicted values from the analytical model proposed by the authors. The results show that the thermal performance of the system can be appropriately determined and described by the analytical model, within a small margin of error. The proposed analytic model can calculate the behavior of a heat discharge system in roofs by defining the system dimensions for the environmental conditions of the location where it is to be used.
