- Anthropogenic Heat: Vehicular emissions , industrial processes , and air conditioning release excess heat, significantly raising urban temperatures.
- Air Pollution and Soot: Black carbon and other particulate matter absorb solar radiation, raising ambient temperatures and worsening the UHI effect .
- Urban Morphology: Dense buildings , narrow streets , and poor airflow create an urban canyon effect , trapping heat within confined spaces
- Consequences: Increased Energy Demand : UHI raises cooling energy use, straining grids and increasing carbon emissions
- Los Angeles Cool Roof Initiative: It requires the use of reflective roofing material s in all new buildings and major renovations to ensure roofs…
