Analysis of heat impacted behavior at vertical façade building based on heat flux mechanism

The most important elements of vertical facade building in open spaces structures are known as urban environment buildings. The building usually plays crucial role to create urban waves that significantly contribute to the urban heat island (UHI) phenomena. This study aims of the thermal behavior of vertical facade building to analyze the mechanism of heat flux. Various types of facade building are measured including brick, concrete, granite and tiles. The analysis based on surface temperatures, ambient temperatures and solar radiation measurements, which were carried out in-situ of the selected facade building materials. The heat characteristics of each building are obtained throughout the day and the surface temperature of each physical element is classified according to temperature and types of material. Among the facade building materials, granite is more heated in 2.7 times than brick wall and it releases a substantial amount of heat into the atmosphere through radiation and convection. As a conclusion, granite may be not good material for the construction of vertical buildings. These conclusions indicate on the suitability of surfacing materials should be chosen in order to help mitigate the UHI phenomena.
