ارزیابی چرخه عمر مواد رایج برای سایه پنجره خارجی مورد استفاده در ساختمان های مسکونی

Life cycle assessment (LCA) wasused to evaluate the environmental effects of the aforementioned materials in typical exterior shadings used in residential buildings. The study compiled a Life-Cycle Inventory (LCI) for quantifying and characterizing the energy consumption and emissions to the environment of these common materials during the life cycle of solar shadings. A life cycle methodology that follows the International Organization for Standardization (ISO) 14040 standard for life cycle assessment was used in this study. Based on the analysis conducted, the positive and negative effects of aluminum and wood shadings on environment for different types of shadings are presented. It was concluded that wood shadings are more environmentally-friendly than aluminum shadings during their life cycles and are better alternatives to be used by building professionals to achieve a more sustainable design.
