Classification, Mitigations and Methods to Detect UHI: A Review

Venkata Ajay Kumar Vardhu, Dr. Anupama Sharma

Abstract:
Because of urbanisation, surfaces of buildings and pavements have increasingly displaced green areas in urban areas. Because of this, solar energy is absorbed by roads, buildings, & rooftops, increasing the surface temperature over that of the surrounding air. This is known as an "Urban Heat Island" (UHI). Urban heat islands can worsen the quality of the environment where people live, increase energy demand, elevate ground-level ozone, and potentially raise death rates. Because of the seriousness of the situation, considerable study has been conducted, and a lot of literature on the subject is now available. This review presents the types, causes, effects, mitigation measures and methods to detect the UHI with their limitations. One of the major findings is that increasing landscaping areas and using high-albedo materials have a great effect on reducing UHI. The majority of researchers are working towards the detection of UHI and suggesting mitigation strategies, then reviewing the implemented mitigation measures and policy making.
