Energy consumption characteristics in residential houses in Danang, Vietnam

Abstract

Residential energy consumption has been increasing significantly in Danang, Vietnam, in recent years due to improvement in living standards. In order to plan housing energy conservation measures, it is necessary to clarify housing information, people's lifestyles, energy consumption style and usage of energy equipment. The purpose of this study is to clarify the energy consumption characteristics for further energy simulation analysis in the next step. For this purpose, a questionnaire survey of 300 households in Son Tra district, Danang was conducted in March 2022. The power consumption data during 2019 - 2021 were obtained through the local Department of Electricity (EVN). An analysis was performed on the information collected to provide insight into the current energy usage in Son Tra. The results showed that the main factors of household that effect the energy consumption were number of air conditionners, outdoor temperature, number of storeys and family size. Through this study, basic documents for energy saving measures and policy making have been obtained; Energy saving measures will be considered through simulation in the near future as the next step.
