This article explores the concept of green hospitals and the importance of reducing energy consumption in healthcare facilities. Green hospitals integrate energy-efficient systems, renewable energy sources, sustainable building materials, and waste reduction strategies to minimize their environmental impact. The article presents statistics on energy consumption in traditional hospitals, highlighting the main areas where energy is consumed, such as HVAC systems, lighting, and medical equipment. Various strategies for reducing energy consumption are discussed, including the use of advanced HVAC systems, smart lighting, renewable energy integration, and retrofitting buildings with energy-efficient materials. Technological innovations, such as building automation systems and energy management systems, play a crucial role in enhancing energy efficiency. The article includes case studies of hospitals like Gundersen Health System, Cleveland Clinic, and Dell Children’s Medical Center, demonstrating successful implementation of green practices and significant energy savings. It also addresses the challenges and barriers to adopting green practices, such as high initial costs, resistance to change, regulatory issues, and technical challenges, with specific comparisons to the situation in Iran. The economic benefits of green hospitals, including cost savings on energy bills, increased property value, and access to financial incentives, are emphasized. Additionally, the environmental impact of green hospitals, such as the reduction of carbon footprints and improved waste management, along with the positive effects on patient health and staff well-being, are discussed. The article concludes with a call to action for healthcare providers and policymakers worldwide, including in Iran, to invest in energy-efficient solutions and green practices to achieve long-term sustainability, environmental preservation, and enhanced health outcomes.
