Abstract

Background and Aim: In recent years, the construction industry, especially hospitals affected by sustainable development, have created concepts such as "sustainable building" and "green hospital". With the development of implementation and evaluation systems of Green Hospital, various methods were presented. The common point of all these methods was the three areas of optimal consumption of water, energy, and less waste generation. This study was conducted to investigate the status of these areas. Methods: This is a retrospective descriptive cross-sectional study. The research population includes a selected military hospital in Tehran, Iran. Information on the consumption and cost of energy, water, and also the amount of waste production over a period of three years (2014-2016) in 2017 were collected and analyzed. Results: On average, the hospital consumes 80.79 kWh of electricity and 12.12 m3 of gas at a cost of 25861 Rials and 10808 Rials per active day bed, respectively. This statistic is active for 1124 liters of water consumption at a cost of 16,993 Rials per day bed. Waste production was on average 3.67 kg per active day bed, of which 42 was infectious waste. Conclusion: The results showed that water and electricity consumption were 2.20 and 10.1 times the existing standards, respectively. The average production of total waste was 2.5 to 3.7 times and infectious waste was estimated to be 27 higher than international standards. It is recommended that hospitals adopt environmental protection strategies, hold training courses, manage waste, and allocate the necessary funds. In the macro dimension, the binding of these measures and the development of local indicators will be a useful solution. The lack of mandatory standards for measuring and reducing the studied indicators is a national challenge and it is suggested that the hospital reduces the statistics. © 2020 Baqiyatallah University of Medical Sciences.
