Quantitative Analysis on Steel Framed Roof’s Temperature Effect

Article Preview

Abstract:

With the high speed urbanization process during last two decades, city underlaying surface area and structure changed rapidly, which resulted in urban heat island effect and a series of thermal environment effect.This topic has been received widespread attention from many researchers. Among all kinds of underlaying surfaces, steel framed roof, as a kind of widely used building material, was found playing an important role on contribution to warm regional thermal environment. So it is necessary to study the relationship between steel framed roof and temperature. Based on analyzing Landsat TM image of Shijiazhuang city by remote sensing software, we found that steel framed roof can warm city environment 2-4℃, its area ratio and land surface temperature have a quadratic curve fitting with correlation of 0.7898.
