Urban Heat & Albedo

Heat Resilience measures how well a surface reflects sunlight instead of absorbing it as heat (albedo). Higher albedo (lighter, reflective surfaces like concrete or light roofs) means lower heat absorption and better heat resilience. Lower albedo (dark surfaces like asphalt) absorbs more heat and increases urban heat stress.

Option 1: Roof Level Global Data

Interactive rooftop analysis


To view detailed rooftop information, zoom in to a building, and click on any rooftop. The popup will display the Heat Resilience Score, Heat Resilience Percentage, Surface Temperature (°C), and Roof Albedo (% Sunlight Reflection). Note: Rooftop-level data is currently available only in selected regions worldwide.

Option 2 : Limited Data

● Darker surfaces absorb more solar energy. • Reflective surfaces stay cooler
