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


  • The intent of this criterion is to ensure incorporation of design strategies that will aid in the reduction of UHIE.

Maximum Points: 2

1) Appraisal

Appraisal – 1 ( Optional for 2 points )

  • Demonstrate the temperature reduction (in °C) from the GRIHA base case as per the alternatives mentioned below (refer to Appendix 1F).
Alternative – 1
  • Demonstrate temperature reduction in the predicted hourly average air temperature (°C) from the GRIHA base case by performing calculations as per Table (Given below).
DESIGN TO MITIGATE UHIE APPRAISAL
Alternative – 2
  • Demonstrate that the difference in peak air temperature has been achieved through dynamic UHIE simulations from the GRIHA base case as per Table (Given below).
DESIGN TO MITIGATE UHIE APPRAISAL ONE

2) Compliance

Compliance – 1

  • Submit a site plan (.dwg format) with legends, mentioning the building heights and external surface finishes such as soft paved / covered with high SRI paints / shaded by trees / vegetated pergolas/solar panels.

Compliance – 2

  • Submit purchase orders reflecting full quantities of high SRI paints/tiles, solar panels, etc.

Compliance – 3

  • Submit the technical specifications/brochures of high SRI paints/tiles, solar panels, etc., to demonstrate compliance with Appraisal – 1 ( Optional for 2 points )

OR

  • Submit a valid GRIHA Product Catalogue certificate as applicable for the products used.

Compliance – 4

  • Upload date-stamped photographs with the description of the measures implemented within the site premises.
Alternative – 1

Compliance – 5

  • Submit calculations using the GRIHA UHIE calculator to demonstrate compliance.
Alternative – 2

Compliance – 6

  • Submit a simulation report (along with input and output files) to demonstrate compliance.
