Abstract

Highlights: A case study of a 1250+ bed multi-specialty Indian hospital building is presented. Energy consumption (%) in the form of each mode of energy on site is presented. Seasonal variation of electricity demand is shown. The Energy Performance Index (EPI) of the building is calculated. The Calculated EPI is compared with the benchmark EPI. Abstract: Buildings account for nearly 40% of global energy consumption and almost one third of global greenhouse gas emissions. In India, buildings account for one-third of the country's overall energy consumption. The commercial building sector in India has been growing at a steady rate since the last decade. It includes hospital buildings, which demand greater energy than other commercial buildings because of their 24-hour operation, use of sophisticated medical equipment and a great dependency on mechanical and ventilation systems to maintain optimum indoor conditions for patients. Huge scope exists for energy conservation in hospital buildings and it is imperative keeping in view the growing population and demand. Energy audit is done to identify energy consuming areas in a building, with the purpose of reducing consumption and eliminating wastages. This paper presents a case study on energy performance of a 1250 + bed multi super specialty hospital building, located in the National Capital Region of India and falling under Composite Climate Zone as per ECBC 2017. The study puts forward the important metric of Energy Performance Index (EPI) for the said hospital building with the aim that it will contribute to set energy performance benchmarks for upcoming and other hospitals of this scale and also raise awareness about energy performance benchmarking. During the selected period of April 2019-March 2020, the hospital consumed a total of 43, 421.15 MWh of energy. Electricity purchased from grid was the dominant energy type, providing 64% of overall energy. Seasonal variation of electricity demand over the one-year period was compared with temperature changes in the Composite Climate. Peak electricity demand was observed in the month of August. The Energy Performance Index of the hospital building was calculated to be 290.98 kWh/m 2 /year, which was near the empirical benchmark of 264 kWh/m 2 /year specified by a BEE-UNDP study from 2017.
