Abstract:
In the design phase of any industry building, appropriate material selection is critical for the entire project. A poor choice of material may affect the quality of the project, lead to high cost during the long term operation and maintenance phases, and even endangering humans and the environment. Since the inception of the United States Green Building Council (USGBC) in 1993, “green” buildings have become a hot topic and people have become concerned about how sustainable their buildings are. In order to determine the level of sustainability in buildings, the Leadership in Energy and Environmental Design (LEED) has developed a rating system that has been established now as the common denominator in the industry. However, the LEED rating system simplifies, or even ignores, explicit considerations for Lifecycle Assessment (LCA) in determining the selection of building materials. This lack of explicit consideration for LCA does not permit a full assessment in determining how truly sustainable the chosen materials are.
This research analyses the environmental factors affecting the choice of green materials in three industry building system, Lightweight Steel Framing system (LSF), Insulated Concrete Form system (ICF), 3D panel System, with considering the total quantities of the environmental factors in life cycle stages by using the software (Athena). This research study and compare environmentally the three systems and components, including foundations, walls, roofing in the context of a system. According to the results and their comparisons, it became clear that the Lightweight Steel Framing system (LSF) and 3D panel system have energy consumption and emissions levels by almost same and Insulated Concrete Form system (ICF) in proportion, emissions and energy consumption is much higher.
