Overview of Zero Energy Buildings

We help make your building smart and improve its energy self-sufficiency.

  • What is a Zero Energy Building
    • A green building that minimizes energy demand and uses renewable energy to reduce total energy consumption.
    • In addition to energy savings, incentives such as tax benefits, relaxed floor area ratio, and building height regulations are provided, increasing interest in zero energy buildings.

  • Zero Energy Building Certification Roadmap

Introduction to ZEB Certification System

  • Overview of Certification System
    • A certification system that grants zero energy building grades (1 to 5) based on energy self-sufficiency for green buildings that minimize energy demand and utilize renewable energy.
      • Up to 15% relaxation in building regulations such as floor area ratio and building height
  • Certification Criteria

    Criteria 1
    Building Energy Analysis Program (ECO2) Evaluation
    Criteria 2
    Building Energy Analysis Program (ECO2) Evaluation
    Criteria 3

    Checklist Evaluation

    Item-based applicability assessment

    - Residential: under 90 kWh/m²·year
    - Non-residential: under 140 kWh/m²·year
    Ratio of renewable energy production among building energy consumption
    - Energy consumption monitoring and real-time management system
    Cooling/heating/hot water/lighting/ventilation demand and renewable energy evaluation
    Primary energy consumption (kWh/m²·year) = Σ energy demand × conversion factor
    Cooling/heating/hot water/lighting/ventilation consumption and renewable energy evaluation
    Energy self-sufficiency (%) = (primary energy production per unit area × 100)
    - (BEMS) 9 evaluation items including data collection, display, monitoring, and control integration
    - (Remote metering) 6 evaluation items including data collection, display, meter management, and data handling
    - (3 additional recommended items)
  • Certification Incentives
    • The government provides incentives such as relaxed floor area ratio and building height regulations to promote zero energy buildings.
      • Up to 15% relaxation in building regulations such as floor area ratio and building height
