Abstract

This research is to study on the energy consumption of the Government Lottery Office (GLO) which is applied by statistical tools such as linear regression analysis, multiple linear regression analysis and cumulative sum control chart (CUSUM control chart). The statistical tools could find energy performance indicators (EnPI) in 3 parts as organization, chilled water system and equipment. The experiments showed that working time of chiller and cooling degree days (CDD) were factors which effected to energy consumption in organization part. The factor of energy consumption of chiller system part was working time of chiller and opening period time of air handling unit (AHU). The coefficient of performance (COP) of chiller was an effected factor of energy consumption of equipment part. EnPI of organization and chilled water system parts were forecasted in term of energy consumption in 2020. The results found that energy consumption of the parts decreased by 7.34% and 8.59%, respectively. A correlation coefficient squared (R2) was more than 0.75 that was appropriately used the EnPI of organization and chilled water system parts for predicted energy consumption in the future.
