Buildings are responsible for nearly about 40 percent of the world’s total energy consumption and about 36 percent of world carbon dioxide emissions. Application of the effective thermal insulation in building in Saudi Arabia is one of the important issues from the aspect of energy economy. The implementation of traditional thermal building insulation materials and solutions of today have the drawback that it result in thick building envelopes due to the increasingly demanding of thermal insulation requirements. In the present paper, an innovation design for building in Saudi Arabia is applied in order to improve its thermal characteristics. This technique is related to the field of architectural engineering instead of using traditional thermal materials. In order to approve the effectiveness of the proposed technique, numerical simulation of the proposed design using CFD code. The obtained results showed that the proposed architectural building design improves the thermal characteristics of the building by reducing the air temperature flowing over it. This can lead to saving energy consumption without using any of traditional insulation materials.
