Energy consumption prediction and simulator

Abstract

Energy audit is a method to analyse energy usage in a building, or area. This method is very effective but also very time and cost consuming. To help this issue, energy simulator is used to simulate the electrical energy consumption. Somehow, these simulators cannot correlate energy driving factor with energy consumption for commercial or industrial sites. It cannot predict electrical energy consumption based on occupant behaviour or various driving factors. For an institutional site that have many driving factors, such as students’ activities, lecturers’ activities, and others, it is hard to perform detail energy audit due to time and cost consuming. To help energy manager, new simulator that can predict electrical energy based on behaviours and driving factors is needed. Hence, this study is carried out to develop an excel template to predict electrical energy consumption for institutional site. Walkthrough energy audit is performed as an input data for the template. Data such as power rating, usage time and others is collected. Estimated electrical energy consumption obtained from simulator is compared with data from electric meter. Correction made to correlate predicted electrical energy consumption with real time electrical energy consumption. Result obtained will be one-year prediction of electrical energy consumption. Based on result, some energy saving measure will be proposed and its corresponding reduction in energy consumption and utility bill will be calculated.
