Structural And Environmental Design, a study of using green roofs system in construction.

Abstract

Green or sustainable architecture considered as one of the new directions of architectural - thinking which is interested in the relationship between the environment and the building. So, it meets the present needs without omission of the future needs of the next generations, and it contributes to decrease the effect of buildings on environment, also decrease the buildup and working costs , so, it is a high quality system meets the surrounding environment with the least side effects. It is an invitation to better deal with our environment. Our building consists of a basement floor consisting of a garage, a ground floor consisting of shops, and two residential floors repeated three times with a total area of (9113) m2. The project contains a detailed structural study, analysis of the structural elements, different expected loads, the structural design of these elements, and preparing the executive plans according to the existing design for all structural elements which forms the structural frame of the building. And from the environmental side the concentration was on the green roofs, that provide ecosystem services in urban areas, including improved storm-water management, better regulation of building temperatures, reduced urban heat-island effects, and increased urban wildlife habitat. There was a meeting point between the environmental and structural section of the work in terms of loads. The expected load was calculated from the addition of the Green Roof. Dead and live loads were increased due to green roofs weight and systems. so, we had to use special structural system so the solid slabs were used under green surfaces, and it keeps the structural cost in reasonable limits. All architectural and structural plans for the building were prepared. It was drawn with a threedimensional technique. The distribution of the green surfaces was shown in the building, and attached with the project.

Key words: structural design, green roof, green building, environmental study.
