The study conducted by the Centre for Science and Environment (CSE) explores the impact of different urban forms on heat resilience.
Key findings and recommendations include:
- Morphology Influence: Areas with open highrise, open midrise, and compact midrise urban morphologies show lower land surface temperatures (LST), indicating better heat resilience.
- Low-rise areas with sparse vegetation tend to have higher LST.
- Blue/Green Infrastructure: Greenery, like trees, shrubs, and grass, enhances microclimates. Effective vegetation cover (EVC) reduces LST; trees with thick foliage are more effective.
- Floor Space Index (FSI): Higher FSI correlates with lower LST. Increased FSI results in decreased temperatures.
- Street Orientation: North-south-oriented streets have higher LST due to sun exposure, offering guidelines for urban planning.
- Cooling Solutions: Different urban forms can have distinct zoning regulations for heat resilience, such as shaded walkways, cool roofs, and high EVC.
- Adapting Urban Plans: Cities should amend building by-laws and master plans based on factors influencing heat gain.
- Impact on Energy Consumption: A 1°C temperature decrease can lead to a 2% reduction in the city’s power consumption.
Usage: The solutions can be used in governance/Disaster Management Questions.
