INTENT
The intent of this criterion is to ensure incorporation of design strategies that will aid in the reduction of UHIE.
Maximum Points: 2
APPRAISAL
1.Demonstrate the temperature reduction (in °C) from the GRIHA base case as per the alternatives mentioned below.
Alternative 1
Demonstrate temperature reduction in the predicted hourly average air temperature (°C) from the GRIHA base case by performing calculations as per Table below.
| Reduction in Predicted Hourly Average Air Temperature (°C) | Points |
| 1.50 C ≤ base case | 1 |
| 2.50 C ≤ base case | 2 |
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 below.
| Reduction in Peak Air Temperature (°C) | Points |
| 10 C ≤ base case | 1 |
| 20 C ≤ base case | 2 |
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.
2.Submit purchase orders reflecting full quantities of high SRI paints/tiles, solar panels, etc.
3.Submit the technical specifications/brochures of high SRI paints/tiles, solar panels, etc., to demonstrate compliance with Appraisal 1.
OR
Submit a valid GRIHA Product Catalogue certificate as applicable for the products used.
4.Upload date-stamped photographs with the description of the measures implemented within the site premises
5. For alternative 1 submit calculations using GRIHA UHIE calculator to demonstrate compliance.
6.For alternative 2 Submit a simulation report (along with input and output files) to demonstrate compliance.
