The Effect of Changing Trombe Wall Component on the Thermal Load

In this research, effects of changing Trombe wall components on the thermal load in the building has been studied and stimulating it with the use of Java language to calculate thermal load, solar gain and auxiliary energy that have to be used according to these changes. Besides, illustrating diagrams have been drawn for the following indications changes1-Wall type (thermal mass).2-Thermal mass thickness.3-Trombe wall area by total wall area.4-Layers count of glass coat (one layer- two layers or three layers).Chosen the best model to be applied as the designing model for any building in Syria that includes passive solar systems. The aforementioned program can be applied to include other important changes. Also, an important result, which is energy saving valued by 83%, has been obtained when using Trombe wall. In addition to avoid the emission of environment-unfriendly gases.
