Building construction is a growing industry in our country, Iran, and due to its environmental impacts it requires more accurate and careful policies. In this article, ceiling as an essential element of the building, has been studied from the environmental, economical and social perspectives. Environmental issues cover items such as global warming, acidification, fossil fuel depletion, etc. Acceptance of a ceiling, technically and the approval of engineers and contractors have been investigated as social issues. On the other hand we have studied the economical issues that have determining role in confirming a system. To achieve this purpose, we have chosen life cycle assessment (LCA) approach and the ceilings have been modeled in BEES (Building for Environmental and Economical Sustainability) software. This program can analyze the ceilings environmental and economical points of view simultaneously. A special questionnaire was prepared for asking the experts about technical and constructional aspects of the proposed ceilings. The results of these two different approaches were analyzed and finally it was found that some of the modern ceilings reduce the environmental burdens, and at the same time their construction are more simple, therefore this is worth paying attention in future policies for building industry.
