Energy Performance

Mandatory requirement 1


Demonstrate energy efficiency of the building to reduce environmental impacts from
excessive energy use.

Compliance Options:

The project can demonstrate energy performance of the facility through one of the
following options:

Option 1:

Depending upon the typology, project must meet the respective IGBC rating – minimum
energy performance requirement. Refer the respective IGBC rating for the minimum
energy performance requirements.

Option 2:

Calculate the Energy Performance Index Ratio (EPI Ratio) as below:

( )= /

The actual energy performance index ratio of the project should be less than or equal to
the design energy performance index on annual basis.
This can be demonstrated through Energy Simulation approach.

Option 3:

Demonstrate that the energy performance of major equipment such as HVAC systems
and Lighting are meeting the Energy Conservation Building Code requirements

  1. For HVAC system, the design COP should be greater than or equal to the
    prescribed COP as per Energy Conservation Building Code (ECBC) 2017.
  2. For Lighting the Lighting Power Density (LPD) should be less than or equal
    to the LPD requirements prescribed in ECBC 2017.
