Urban Heat Island (UHI)
Definition
A metropolitan area that is significantly warmer than its surrounding rural areas due to human activities, resulting in increased energy consumption, elevated emissions of air pollutants, and impaired water quality.
Purpose
Understand and mitigate the impact of urbanization on local climates by implementing strategies to reduce heat absorption and enhance urban cooling.
Examples of Use
- Designing green roofs and urban parks to reduce heat.
- Implementing reflective building materials and cool pavements.
- Planning urban tree canopies and increasing vegetation.
- Promoting energy-efficient building designs and sustainable urban planning practices.
- Encouraging the use of water features and natural ventilation.

Notes
UHI effects can increase energy consumption, elevate emissions of air pollutants, and impair water quality, making mitigation efforts crucial for urban sustainability. Effective strategies can lead to energy savings, improved urban livability, and better public health outcomes.
