| Abstract |
This study examines actual reductions in energy consumption in buildings that obtained energy efficiency certification. Policy periods were
defined based on major regulatory changes over the past decade, and energy use data from representative certified buildings in each period
were analyzed. The results indicate that Energy Use Intensity (EUI) decreased over successive policy periods and with higher certification
grades. In addition, a comparative analysis using a Change Point Model for buildings of similar size and function showed a reduction in
heating energy consumption as policies advanced. These findings demonstrate that energy-saving measures, including stricter Building Energy
Codes and mandatory certification, have contributed to measurable reductions in building energy use. |
