ENERGY CONSERVATION AND MITIGATION USING SIX-SIGMA METHODOLOGY AT ISABELA STATE UNIVERSITY, ANGADANAN, ISABELA, PHILIPPINES
A proposed application of Six Sigma is through the analysis of energy management. The DMAIC method analyzes how to conserve energy. Also, Six Sigma techniques were used in this study. Load inventory was done, classifying potential loads with their demands. Data such as monthly bills gives information needed along the process. The process illustrates activities that were done to satisfy customers’ requirements. Six years of energy consumption were recorded. The average energy consumption per year is 83,851.37 kWhr, as compared to the year 2022, which has a significant increase of 164%. Air-conditioning units’ account for 68.60% or more than two-thirds of the total demand. This illustrates that other combined loads are just half the demand of ACUs. Energy awareness campaigns were conducted for the group of students and faculty. There is a percentage reduction of 5.59% after the intervention. A test of significance using two independent samples t-tests were done and revealed that the effort had given a sig-value of 0.85 at a confidence interval of 95%, and had no significant effect. However, in terms of monetary consideration, the reduction of 5.59% saved a considerable amount of money and mitigated 0.090 tCO2e of carbon footprint for that particular month. A continuation of the study must be conducted using the same method but consider an automation process or a comprehensive energy audit.
