URBAN HEAT ISLAND INTENSITY-STUDY OF ENERGY BALANCE IN URBAN ENVIRONMENT, A CASE OF PUNE

Abstract

In urban areas temperature is the function of solar radiation as well as emission of energy from different objects, surfaces and materials. The energy emitted by any object of any material is function of its absolute temperature. Characteristics of urban materials, in challenging solar reflectance, thermal emissivity, and heat capacity, also influence urban heat island development. The aim of the paper is to calculate energy emitted for a case in Pune & compare with the proposed case materials. Objectives of paper are to study Intensity of UHI, to study properties of urban materials, calculate the energy emitted for a case in Pune & compare with the proposed case materials. The method used is quantitative comparative analysis by taking a case of commercial (office) building is Pune. The proposed outcome of the paper is to prove that retrofitting the existing materials of buildings that absorb low solar energy work better in urban areas to cater problems regarding UHI. Therefore, this paper recommends using reflective materials on external surface of buildings and surroundings to reduce UHI effects and improve the urban environment.
