Energy audit and analysis of the electricity consumption of an educational building in the Philippines for smart consumption

摘要

Energy audit is the inspection, survey and analysis of energy flows in a building. The goal is to identify energy efficiency opportunities which will not negatively affect the output and operations of the building. The unique case of cleaner production in educational buildings is presented in this study - minimal material flow allows a focus on energy consumption; robust scheduling provides an advantage and equipment usage is between an office and an industrial building. Energy auditing revealed that most of the electricity consumption is due to air conditioning (51%), followed by equipment use (35%) and lighting (14%). Annual carbon dioxide emissions due to electricity consumption are estimated at 433 tons. Recommendations include using energy efficient lighting and exploiting daylighting, adopting a centralized or split-type inverter air conditioning system and implementing minimum energy performance standards (MEPS). Lastly, it is understood that scheduling uniquely plays a very important role in managing the smart consumption of educational buildings.
