Nanotech-Based Cool Materials for Building Energy Efficiency

摘要: Cool materials represent an interesting and acknowledged solution able to produce a threefold benefit: the reduction of cooling energy needs in buildings, mitigation urban heat island phenomenon, counterbalance global warming trend at larger scale. In fact, they are environmentally friendly relatively cost-effective characterized by high solar reflectance infrared thermal emittance properties. Therefore, helpful mitigate microclimate decreasing air surface temperature when applied over building envelopes, i.e., roofs walls, paving surfaces. This chapter will discuss about key research contributions development testing such cool materials’ effectiveness with specific focus on material engineering characterization. More details, recent nanoscale developments be addressed main applications discussed order provide quantitative assessment technology for efficiency.
