Developing energy based benchmark model and detailed energy analysis through school statistical data and field...

Area of Science:

• Building Energy Analysis
• Sustainable Architecture
• Educational Facility Management

Background:

• Many Korean school buildings (20%) exceed 40 years old, necessitating upgrades for safety and energy efficiency.
• The increasing number of aging educational facilities presents significant challenges for learning environments and energy consumption.
• Aged school infrastructure requires innovative solutions for improved performance and resource management.

Purpose of the Study:

• To develop an energy-based benchmark model (EBBM) for Korean school buildings.
• To establish methods for utilizing EBBM to identify energy-saving opportunities in educational facilities.
• To create data-driven analysis rules for optimizing school building energy performance.

Main Methods:

• Analysis of the Korea education database to classify an energy-based benchmark model.
• Detailed system analysis of 10 schools to review EBBM applicability.
• Data-driven energy analysis using building energy flow charts to estimate consumption and savings.

Main Results:

• The developed EBBM demonstrated high accuracy, with a difference of less than 10% between calculated and actual values.
• The study enabled comparison of energy consumption across school buildings of varying sizes.
• Analysis revealed that school classrooms are the largest energy consumers, primarily for heating and cooling.

Conclusions:

• The energy-based benchmark model (EBBM) is a viable tool for assessing and improving energy efficiency in diverse school buildings.
• EBBM facilitates data-driven insights into energy consumption patterns, enabling targeted energy-saving strategies.
• Optimizing energy use in school classrooms, particularly for thermal comfort, is crucial for overall facility energy reduction.
