The study aims at evaluating some buildings at the Isra University according to LEED standards. Further , proposing the development the selected buildings for the purpose upgrading the standards according to LEED which includes (location transportation , site sustainability , water sufficiency , energy and atmosphere , quality of internal environment and innovation ) Three building where selected for the study: the faculty of Engineering , Arts , and pharmacy. The buildings were evaluated based on field survey, personal interviews blueprints designs and the examining of documents. The researcher found that when evaluating using the LEED rating system , the faculty of Engineering obtained an acceptable grade of ( 45.5) points out of 110 , faculty of arts (51.5) , and pharmacy (45) points ,the implementation of all mandatory conditions . The researcher recommends on current status: (1) documenting executive plans and information related to specialization. (2) Water, electricity, and energy of each building should be separated. The researcher after suggestion of strategic measures to raise the efficiency of those buildings , concluded that the assessment of the faculty of Engineering rose to the golden level with ( 79) points , Arts the platinum level with (82.5) points ; and Pharmacy the golden level with (76.5) points , after LEED standards were implemented , which can be achived with in the university resources . The researcher and study recommends : 1) The study should be taken into consideration to raise the environmental efficiency level of the university buildings to become the first university in Jordan to apply American LEED rating system. 2)Disseminate awareness among employees and students highlighting the significance of sustainability and team work in achieving an architectural project.
