Cost-benefit impacts of sustainable buildings in Iran

Abstract

The green building could be a building with different usage. In the meantime, either entire or a considerable section of the production cycle of the energy as well as the consumption of it occur inside the building. Meanwhile, the sustainable building, or the green building, is consisted of green materials for the environment, and the modern technologies related to green energy. Sustainable design, protection, and water consumption saving, controlling the energy, environmental protection, the quality of the interior space of the building and the protection of resources and materials are the general principles of each sustainable building. The purpose of creating a sustainable or green building is utilizing the new durable construction equipment and materials so that the building itself can produce energy. In this master thesis, comparing the sustainable building with the conventional building in Iran regarding cost and benefit, energy consumption, environmental protection, and materials is described. It is also expressing the necessity of implementing sustainable building in Iran. The results show that although the initial cost of the green building in Iran is about 14 percent more than the conventional building, the energy consumption has an impressive reduction. Also, there will be a significant reduction in final costs for sustainable buildings, and this money will back during the lifecycle of the building. So the simple payback of the sustainable building in Iran is around 14 years.
