To establish effective policies for reducing CO₂ emissions in the building sector, it is essential to analyze the feasibility of regulations. In this regard this study seeks to analyze the effectiveness of Energy Performance Certificate (EPC), Display Energy Certificate (DEC), and Minimum Energy Efficiency Standard (MEES) regulations implemented in the UK. In particular, it analyzes the effectiveness in terms of mandatory issuance of the building energy rating certificates (i.e., EPC and DEC) and the minimum energy performance regulations (i.e., MEES regulation) of the building. To this end, the effectiveness of the system implemented in the UK was analyzed using 31,915 EPC and 31,715 DEC data. The analysis found that the CO₂ emissions of properties due to the EPC and DEP issuance obligations decreased further in 2022 than in 2013. It was also found that starting in 2018 when the MEES regulation was implemented, the CO₂ emissions by property type continued to decrease. This is because property owners were highly motivated to improve building energy performance due to the implementation of the MEES regulation. Therefore, it is expected that the findings of this study will serve as important basic data for the policymakers of the government to develop more effective building energy performance improvement policies.
