This study aims to analyze the environmental impact of different glasstypes of a clinic in Assiut University Hospital. The life cycle assessment(LCA) approach evaluates energy usage and its related environmentaleffects. This study will assess the environmental impacts of four typesof window glass manufacturing, which are (1) flat glass, (2) fiber glass,(3) solar glass, and (4) waste glass. The Building Information Modeling(BIM) approach has been used to collect the building constructionquantities, facilitating this task. The LCA has been used to calculateenergy consumption and environmental emissions. As the main findingof this study, the fiber glass has the worst-case scenario with (1.02 Pt),in contrast with the waste glass (recycled glass) with (0.58 Pt), by themid-point method result. Also, the global warming potential and nonrenewableenergy impacts have recorded the highest impact valuesfor the fiber glass with 2939.49 KgCO2 eq.and 46914.97 MJprimary,respectively. Finally, the human health (end-point) method has the mostsignificant share of the adverse environmental impacts for the four glasstypes studied. The study has proposed that the life cycle cost and thedurability and endurance tests must be examined to ensure that wasteglass (recycled) is the best option from all points of view
