Zero Energy Building Rating System

Zero Energy Building Rating System icon

Zero Energy Building Rating System

Zero-Energy Building Certification is awarded to green buildings that minimize the energy load required for buildings and minimize energy consumption by utilizing new and renewable energy sources. The certification is based on the energy self-sufficiency rate, ranging from Grade 1 to Grade 5

Certification targets

  • Buildings eligible for building energy efficiency rating system, where the building owner applies for zero-energy building certification.
  • (Mandatory) Public buildings subject to the submission of energy-saving plans for additional construction with a floor area of 500m² or more, constructed separately on the site of new construction, reconstruction, or existing buildings, are required to display the certification mark for buildings subject to mandatory certification.

Certification grade

Buildings that meet the criteria of Building Energy Efficiency Rating 1++, achieve a self-sufficiency rate of 20% or more, and comply with the installation standards for Building Energy Management Systems (BEMS) or electronic telemetering system is awarded based on the self-sufficiency rate, ranging from Grade 1 to Grade 5.

  • 01

    Building Energy Efficiency Grade 1++ or above

    Building Energy Analysis Program (ECO2) Evaluation

    • For residential buildings: Below 90 kWh/(m²·year)
    • For non-residential buildings: Below 140 kWh/(m²·year)
    • Evaluation of Cooling/Heating/Hot Water/Lighting/Ventilation Consumption and Renewable Energy Production
    • Primary Energy Consumption (kWh/(m²·year)) = Specific Energy Consumption by Use x Primary Energy Conversion Coefficient
  • 02

    Energy self-sufficiency rate of 20% or more

    Building Energy Analysis Program (ECO2) Evaluation

    • Building Energy Efficiency Grade Certification
    • Energy Self-Sufficiency Rate Review Results
    • Evaluation of Cooling/Heating/Hot Water/Lighting/Ventilation Consumption and Renewable Energy Production
    • Energy Self-Sufficiency Rate (%) =
      Unit Area Primary Energy Production kWh/(m²·year) Unit Area Primary Energy Consumption kWh/(m²·year)
      X 100
  • 03

    Installation of BEMS or remote metering electronic devices

    Assessment of Applicability for Each Checklist Item

    • System for Measuring and Managing Energy Consumption in Real-time
    • (BEMS) Evaluation of 9 items including data collection and display, information monitoring, and control system integration
    • (Remote Metering) Evaluation of 6 items including data collection and display, instrument management, and data management (additional recommendation of 3 items)
  • Grade
    Energy Self-Sufficiency Rate
  • 1
    Buildings exceeding 100%
  • 2
    Buildings ranging from over 80% to less than 100%
  • 3
    Buildings ranging from over 60% to less than 80%
  • 4
    Buildings ranging from over 40% to less than 60%
  • 5
    Buildings ranging from over 20% to less than 40%

Certification Procedure

Document evaluation is conducted based on the design documents, and on-site assessment is carried out for self-verification.
