Energy audit of a small commercial hospital building in Ranchi: A case study

Abstract

Energy audit focuses on equipment energy consumption such as lighting, air-conditioning system, elevators, and other devices operating on electricity. Data of the energy consumption recorded are used to identify and rectify by presenting detailed energy audit. Temperature, humidity, and CO2 emission of the building should be measured to conduct the investigation on detail energy analysis. Building utilizes major energy usage accounting to more than 30% overall energy usage. The commissioning and audit process results in the low-energy consumption and low equipment’s cost resulting in higher investment returns. This paper presents a detailed energy audit through a case study on small commercial hospital building located in Ranchi. The pre audit phase suggests that ceiling fans and fluorescent tube lights consume more than 50% of the total energy in the hospital. The energy auditing of the building resulting in annual energy savings of 7697.32 KW i.e. 35 % annual energy saving if recommended suggestions are followed. The recommendation of low-energy consuming equipment’s have payback period less than 6 years leading to higher return rate.
