The building is the main place for humans to feel safe and comfortable. Also, the building does not depend on economic dimension only but depends on the social and environmental dimensions. For that, it is very important to achieve thermal comfort in the building to increase people’s ability to be productive and feel comfortable. It notes that the highest ratio of building constructed with a brick of concrete in North Sinai – Egypt. Therefore, giving special attention to making the building constructed with a brick of concrete low cost is very essential in maintaining the cohesion of the three dimensions of green architecture building. Therefore, the study will include changing the shape of the concrete hollow brick with the same materials and its ratio in manufacturing. To construct the building in less time and decrease construction laborer and the material which use in construction. Also, the study will include some cross sections in external walls to achieve the most suitable section in-wall appropriate with the environment of north Sinai that decreases the overall heat transfer coefficient on the wall of the building. Additionally, that compares the cost of building for the traditional building constructed by brick of concrete with the building constructed by new brick of concrete. Finding will improve the economic and environmental dimension for building constructed with new concrete brick, which can impact directly in the social dimension. Because using the new hollow brick will decrease the energy consumption and the cost with a ratio of 7% in every part during a building’s life cycle.
