ENERGY CONSERVATION BUILDING CODE

If you want know about About the IGBC and its function or About GRIHA and its function or GRIHA rating process or About green building or GRIHA rating & registration please click the link above.


  • The purpose of the Energy Conservation Building Code (Code) is to provide minimum requirements for the energy-efficient design and construction of buildings.
  • The Code also provides two additional sets of incremental requirements for buildings to achieve enhanced levels of energy efficiency that go beyond the minimum requirements.

1) ECBC

  • Minimum energy efficiency standards
  • Applicable to large commercial buildings
  • (connected load of 100 kW/contract demand of 120 kVA and above)

i) ECBC prescribes standards for

  • Building Envelope (Walls, Roofs, Windows) Lighting (Indoor and Outdoor)
  • Heating Ventilation and Air Conditioning (HVAC) System
  • Solar Hot Water Heating
  • Electrical Systems

2) Purpose of ECBC

i) Key objectives of ECBC 2017 development

  • Set a long term vision for building energy efficiency
  • Include new types of buildings
  • Focus on design strategies for reducing energy use
  • Establish a baseline of energy performance and promote buildings that go beyond the code
  • Ease of compliance and enforcement

ii) Typical Electricity Use in Buildings

  • Application of building codes reduces electricity consumption by 25% – 30%
TYPICAL ELECTRICITY USE IN BUILDINGS

3) Scope of ECBC

i) Energy efficiency requirements for the Code

ENERGY EFFICIENCY REQUIREMENTS

4) Compliance and Approach

i) Compliance and Approach

  • Energy Performance Index Ratio (EPI Ratio) is less than or equal to 1.
  • The Energy Performance Index (EPI) of a building is its annual energy consumption in kilowatt-hours per square meter of the building.
  • While calculating the EPI of a building, the area of unconditioned basements shall not be included.
EPI OF THE BUILDING

ii) Determining EPI Ratio

  • The EPI Ratio of a building is the ratio of the EPI of the Proposed Building to the EPI of the Standard Building:
DETERMINING EPI RATIO

5) Building Envelope

Mandatory Requirements
  • Fenestration ( U-Factor, Solar Heat Gain Coefficient, Visual Light Transmittance)
  • Opaque Construction
  • Day lighting
