Abstract

This research aims to 1) design and develop the measure electricity system to display the voltage, electric current, electric power, electric energy cost per unit which can display results immediately, 2) analysis factors that related and affected the use of electricity energy during the off-peak period, 3) plan the electricity consumption management during the off-peak period. The developing of the measurement system for measuring electricity consumption in buildings on the Internet platform a case study of Srivisawawitthaya Building, Faculty of Engineering, Rajamangala University of Technology Srivijaya studied the work process by collecting data on electricity consumption during the off-peak period and studied documents. Then analyzed data by using the principle of the cycle development system in order to develop the system that meet the needs of users as much as possible. The study found that the development of electric power consumption measurement system program abled to measure electrical quantities such as power factor Current, voltage, frequency and power values. by the error value for power factor 2.05 percent, the error value for electric current 1.25 percent, the error value for voltage 0.26% percent, the error value for frequency 2.00% percent, and the error value for electrical energy 0.00 percent. Factors related to and affecting the use of electricity during the Off-Peak period are lighting system 58.56%, air conditioning system 23.62%. The electricity management plan during the Off-Peak period according to the energy conservation guidelines of the Ministry of Energy consists of 3 strategies as follows: strategy 1 increasing energy efficiency: strategy 2 using public relations campaign and creating awareness among personnel of the Faculty of Engineering Rajamangala University of Technology Srivijaya: strategy 3 following up, evaluating and reporting the implementation of saving measures and reduce energy consumption result
