jailcd2018076: "A Review on Retro-reflective Materials as Building Coatings for Urban Heat Island Mitigation"

Abstract

In recent years, the urban heat island effect has become more and more serious, causing different degrees of harm to the residents' life. So there is an urgent need to adopt a stainable strategy to alleviate urban heat island effect. One of the general choices is the use of retro-reflective materials. Their contribution to the urban heat island relief (UHI) caused by urban microclimate overheating is internationally recognized. The demand for related studies on highly insulating building coatings is also growing, addressing the application of the coatings to optical surfaces and heat transfer on building surfaces, also assessing their interaction with the urban heat island effect. This article aims to analyze the current research trends on urban heat island mitigation through a comprehensive survey of scientific articles published in 2014-2017. The survey compiled nearly 20 essays and categorized the commonly used mitigation measures. The analysis showed that the researchers found a series of new retro-reflective materials and measures to mitigate the urban heat island such as the use of glass beads, solar-shading transparent film and the development of traditional
retro-reflective materials. Research on disaster mitigation measures has mainly focused on climates and larger developed urban areas in East Asia, North America and the Mediterranean coast.
