Mosaic Insights was engaged by the CRC for Water Sensitive Cities, the Australian Water Partnership and the Department of Foreign Affairs and Trade to analyse the cooling benefit of urban forestry and irrigation for the city of Amaravati in India, which is currently under construction. Basing spatial information on a masterplan we applied the CRC developed TARGET model to the city-scale and to the street-scale to quantify how urban forestry will impact the temperature and heat stress levels in this new city.
We determined that throughout the city increased street trees and irrigated grass has the potential to reduce temperatures and improve human thermal comfort across the city, while at the street scale adding trees along the canals gives the most benefits in the morning as opposed to the afternoon.
We also conducted street orientation analysis to determine which streets would benefit the most from the shading effects of trees, an analysis of the height-width ratios of different parts of the city to determine whether shading from trees can add cooling value, and an analysis of street orientations to understand those that benefit most from green facades and meteorological analysis of the prevailing winds to potentially influence design decisions for the city.
The insights gained from this project will inform future planning and design decisions for the new city of Amaravti
