Photoluminescent materials are advanced cutting-edge heat-rejecting materials capable of reemitting a part of the absorbed light through radiative/non-thermal recombination of excited electrons to their ground energy state. Photoluminescent materials have recently been developed and tested as advanced non-white heat-rejecting materials for urban heat mitigation application.

The heat mitigation potential and climatic impact of super-cool broadband radiative coolers on a city scale

Day Time Radiative Cooling is the air conditioning of tomorrow. The development of super cool materials can decrease the peak temperature of cities up to 3 C and provide huge energy benefits. Extremelly happy to share the newly published work of our lab, published in the prestigious journal Cell Reports on Physical Science. This is part of the PhD work our our excellent student Jie Feng.

Scientific research on Urban heat islands (UHI) and urban. overheating has set new challenges for societies regarding risk and vulnerabilities, energy demands and mitigation strategies to favor urban environmental quality conditions against urban pollution. This review manuscript addresses systematically 171 relevant studies to identify and characterize gaps in the field of knowledge, through a robust evidence-based analysis focused on identifying taxonomic recurrences, trends in the study of urban fields of impact, global leaderships, mitigation strategies, methodological divergences, remote sensing indexes, data sources, legal frame, among other significant aspects on the context of environmental degradation and energy.

Experimental development and testing of low-cost scalable radiative cooling materials for building applications

Urban overheating has a serious impact on building energy consumption. Daytime radiative cooling materials are an interesting passive solution for refrigeration. However, their costs and complex manufacturing hinder their current application. In this study, a series of scalable and lowcost daytime radiative cooling (DTRC) materials were designed, fabricated, and tested in a moderate climate (Cfb-Köppen-Geiger classification) and compared to aluminum and Vikuiti.

Associated with rapid urbanization and escalation of bushfire events, Sydney has experienced significant air quality degradation in the XXI century. In this study, we present a 15-year retrospective analysis on the influence of individual meteorological factors on major air pollutants (NO2, O3, PM10 and PM2.5) at 14 different sites in Greater Sydney and Illawarra.
