Study of the relationship between the performance of medical centers and the establishment of environmental management system

Introduction: In recent years, many organizations have used management system certification such as the Environmental Management System (EMS). The purpose of present study is to assess the effect of Environmental Management System (ISO14001) on hospital performance. This is an applied (regarding the purpose of the study) and descriptive research and data are gathered through secondary (library) and primary (questionnaires) sources. This is applied and causal.  After confirming the validity and reliability of the questionnaire, it was used for data collection. The research population includes hospital staff. This community was considered limited and therefore all the staff were studied. The results were analyzed using structural equation methods with Smart-PLS software. In addition, the results indicate that three variables of environmental management system, environmental training of human sources and environmental management program have a direct and significant effect on hospital performance.

methods: Gas cogeneration systems have been studied in terms of pollution and noise produced for residents. Due to the multiplicity of primary actuators, only natural gas actuators that can be implemented in residential buildings are considered here. All calculations have been done for residential buildings with EES software and after analyzing the gas cogeneration system, 

Results: The results have been compared with the solar cogeneration system. The initial cost of the systems, the pollution created and the amount of noise in the various prime mover of the cogeneration systems have been examined and the cogeneration system with the solar collector has been described as the cleanest, quietest and the most expensive cogeneration system.

Conclusion: It is possible to use the cogeneration cycle in all areas and in any weather conditions, while the use of the cogeneration cycle is suitable in areas with high hours of solar radiation, which is one of the weaknesses of solar systems.
