Wind catcher Earth air tunnels systems are proposed to be used in modern buildings to minimize the consumption of non-renewable energy. A tunnel in the form of a heat ex-changer burns at a depth of about 4 m below the ground level will acquire the near temperature as the surrounding earth. Therefore, when the ambient air passes through this tunnel, it will be cooled in summer and warmed in winter seasons. This study explore the effect behavior of using Wind catcher Earth air tunnel in designing energy efficient home with renewable energy utilization during early stages of the planning of new societies in Egyptian desert cities. A prototype home for single-family detached houses of 240 m2 in two floors, each floor of 120 m2 with best utilization of the available renewable energies resources is proposed. This prototype home can be suggested to be the design for new single-family detached homes for Egyptian new towns. In order to achieve the above objective, this paper presents a reviewing for passive cooling techniques used in hot arid areas. Then a detailed analysis of the Wind catcher Earth air tunnel used in the suggested energy efficient home. The present study showed that using natural ventilation in the efficient home design for single-family detached houses in new societies in Egypt could save home energy bill and regulate the indoor air movement to achieve indoor thermal comfort, consequently, reduce the need for an electric mechanical means for indoor air movement.
