Development of an Energy Management System for Tertiary Care Hospital, with Special Emphasis on Lighting

Energy efficiency in the hospitals is the growing concern. The hospitals work 24/7 in the very critical situation and having very huge and crucial equipment to use, which consumes energy. India is the third biggest consumer of primary energy after USA and China by 5.6% global share in 2017. In the hospitals the cost spending on the energy expenditure is in lakhs/month so we need to use the energy efficiently to save energy and to reduce the cost. Hospitals can’t be run without energy. Critical equipment used in ICU, operation theatres, emergency department etc. are highly dependent on energy as in its absence there may be chances of interruption in patient care. The aim of this study is to assess the energy efficiency level of the hospital to propose an energy management policy and energy management system. The retrospective study was conducted on the energy efficiency in the facility department, tertiary care hospital, the results showed the compliance to the energy efficiency, the expenditure on the energy and also the Number of lighting fixture which is used in different departments. Based on the study results, peer literature reviews the Energy Management System is developed and policy is made to achieve the energy efficiency in the hospitals, the prioritization is made in the lighting system to switch towards the efficient lighting with the help of pareto principle and ABC analysis which are given to the facility department. The suggestions could help in the tertiary care hospitals to check the compliance on energy efficiency to implement the energy management system by using the PDCA cycle and to move- towards energy efficiency.
