Evaluation of Energy Conservation Potential in Air Conditioning and Lighting Systems Case Study: Large Government Hospital

Abstract

The energy crisis impact to business operations in many sectors. For this reason, the Department of Alternative Energy Development and Efficiency has issued the Energy Conservation Promotion Act (revision 2) B.E. 2550 (2007) to make designated factories and designated buildings perform energy management in a step-by-step for maximum energy efficiency. For achieves the goal of reducing energy use and reducing operating costs. This research aims to present energy conservation solution that are beneficial in a large government hospital in the maximum efficient use of energy and energy costs reduction, by collecting energy consumption data, evaluating energy conservation potential. Non-investment measures and investment measures was defined in order to improve air conditioning systems and lighting systems. The result reveals that most non-investment measures come from changing personnel behaviors, reducing the working time of machine equipment, reducing the number of unnecessary devices, adjusting the operating time. These measures result in energy saving 1,798,355.05 kWh/year, accounting for 8.60% of electricity consumption. Furthermore, investment measures come from the use of new technology to apply, modify major equipment with high efficiency. These measures result in energy saving 8,533,149.68 kWh/years, accounting for 40.82% of electricity consumption
