การตรวจสอบนโยบายและการประเมินปริมาณการใช้ไฟฟ้าในอาคารสำนักงานภาครัฐในประเทศไทย

Abstract

The situation of energy consumption in Thailand tends to increase with the country’s economy, including climate change. This thesis attempts to collect and examine the current information status, study factors affecting electricity consumption, and prepare energy performance indicators for public office buildings under control in Thailand. Focus on analyzing data on factors affecting electricity consumption with multiple regression analysis econometric models with the EViews program, covering data from energy management reports from 2010 to 2021. The study found 49 public office buildings under control with complete data and divided them into two groups based on transformer size: six small and 43 large buildings. Three factors that affect electricity consumption in small public office buildings are air-conditioned areas, working hours, and ambient temperature. While five factors that affect electricity consumption in large public office buildings are air-conditioned areas, non-air-conditioned areas, working hours, number of personnel, and ambient temperature. When considering appropriate indicators for evaluating electricity consumption in public office buildings under control in Thailand, there are two indexes: The Specific Energy Consumption Index (SEC) tracks and controls electricity consumption, reflecting the efficiency of electricity usage over time. The Energy Performance Index (EnPI) considers factors that affect electricity consumption and can be compared to the SEC to establish criteria for evaluation. Both indices can use guidelines for determining energy management evaluation standards for public office buildings under control.
