A Study Case of Mathematical Calculation of Urban Heat Island Intensity Based on Urban Geometry.

Abstract

The paper presents a method to simulate the maximum intensity of urban heat island based on urban geometry using H/W parameters. Urban heat island is determined by the increase in the temperatures in city centers with higher density of buildings comparing to the surrounding rural areas. The research method is based on Oke’s model. An area in the city center with high construction density was selected to simulate the intensity of urban heat island. The research shows that population growth affects the urbanization process; over the years, the urban land area is affected by the expansion of the heat island effect. The calculations show that the higher the building is and the further it is situated from the road; the more is the intensity of city heat island. Using Oke’s model to estimate the intensity of the heat island based on the ratio of the building height and distance from the road makes THE process of optimal modeling possible. As a result, the planner can offer solutions to eliminate the negative impact of the urban heat island effect.
