Evaluation in the construction process of hospitals in terms of environmental sustainability and researching of renewable energy applications

In recent years, investments in the healthcare sector regarding quality, efficiency, and sustainability have gained momentum in our country, with both the government and private sector making significant efforts. The use of renewable energy systems during hospital construction and operation periods enhances environmental sustainability in line with national and international legislation and standards, strengthening healthcare services. This study explores the environmental sustainability of renewable energy applications in hospital construction in Türkiye, using Corbin and Strauss's Qualitative Data Analysis Method - Document Analysis. The study examines applicable approaches and analyzes the share of operating costs that can be covered by calculating the energy costs through a simple simulation method based on the initial investment costs. The study shows that the energy demand, primarily dependent on criteria such as bed capacity and expected usage times of heating systems, will vary independently of estimated electricity consumption. It has been understood that facilities such as hospitals, whose water, electricity and heating-cooling consumption costs can reach billions of lira, can reduce their impact on climate change by reducing their resource consumption by up to 30% with properly managed sustainable practices. Research has shown that the use of renewable energy methods or hybrid systems that generate electricity through a generator, alongside renewable energy systems, provides many benefits, such as high quality and low costs, energy savings through with CHP (Combined Heat and Power)/CCHP (Combined Cooling, Heat and Power) systems, and efficient energy usage. Moreover, these applications offer the possibility of sending excess energy to the grid or storing it in suitable batteries for later use. In conclusion, the implementation of environmentally-friendly policies can enhance our country's prosperity and provide a healthy environment for society by reducing the use of fossil fuels and ensuring adherence to established sustainability standards in all projects.
