BELS (Building-Housing Energy-Efficiency Labeling System) is a third-party certification system that rates buildings following a requirement to label energy efficiency performance based on the Act on Improvement of Energy Consumption Performance of Buildings. Buildings are evaluated based on the value of BEI (Building Energy Index) derived from primary energy consumption based on the government's energy consumption performance standard.
Certifications and labels under this system are conducted by organizations registered as BELS operators, including registered housing performance evaluation agencies, designated inspection and certification bodies, or registered building survey organizations that have officially filed to perform BELS evaluations.
The energy efficiency performance is displayed using a five-level star rating system (★ to ★★★★★).
