The Ministry of Energy of Thailand has seen the country's energy consumption trend increasing. Therefore, an energy conservation plan was issued to set goals and action plans for energy conservation over a period of 20 years starting from 2011 in accordance with the energy conservation law of the Energy Conservation Promotion Act of 1992. The amended version of 2007 stipulates that an energy management report should be submitted regularly. The report contains interesting information to study measures that should promote effective energy conservation results.

         This research presents the amount of energy use and measures that should be promoted from data collected from the Energy Conservation Report sent to the Department of Alternative Energy Development and Efficiency over the past 10 years from 2010 to 2019, totaling 26,595 volumes. There is an economical effect on investment in each type of measure followed by 1. The housekeeping measures (HK) result is by determining the right on-off time is 45.84%, 2. The Machine change (MC) measure result is by changing from tungsten-halogen bulbs to LED bulbs is 0.797 %, 3. The Produce Improvement (PI) measure by using the variable speed system (VVVF) on the motor of the cold-water pump is 0.797 %. And other processes result by Enable-Disable Control is 2.34 %.
