School building energy assessment using lean energy management strategies

Abstract

In Malaysia, there are approximately 10,220 active schools, and these schools’ electricity bills are under the responsibility of the Malaysian Ministry of Education. The demand for energy use is expected to rise dramatically in the coming years due to many factors such as the increasing number of student enrolments and the demand for a comfortable indoor environment in response to global climate effects. Therefore, there are many ideas, concepts, and technologies that have been introduced towards energy conservation in buildings. This study aims to identify key implementation of energy conservation measures and audit energy consumption of five secondary schools. Case studies derived were from schools that participated in Energy Efficiency Challenge hosted by the Energy Commission. It was found that the schools’ usage of electricity exceeded their need. Based on the implementation of energy management conservation measures throughout 2016 to 2019, there were gradual reductions and downtrends in energy consumption graphs.
