Passive radiative cooling: state-of-the-art materialsPassive radiative cooling: state-of-the-art materialsΚαινοτόμα ψυχρά υλικά: κλιματισμός μέσω ακτινοβολίας Μεταπτυχιακή Διατριβή Master Thesis 2020-09-032020enHere we analyze two state – of – the - art passive radiative cooling coatings. Radiative cooling materials emit radiation that goes directly to outer space through the atmospheric window while the percentage of radiation that they absorb is as low as possible. The atmospheric window is the window of 8 – 13 μm, where the infrared radiation passes immediately to outer space without any significant absorption by the Earth’s atmosphere. Thus, it manages to acquire sub – ambient surface temperature which can contribute to improving the thermal comfort conditions in the buildings, the energy conservation, the mitigation of the urban heat island effect while it can also be used for low – grade heat dissipation from power stations Based on the most recent research papers, we fabricate two radiative materials and we study their performances.http://creativecommons.org/licenses/by-nc-nd/4.0/Πολυτεχνείο Κρήτης::Σχολή Μηχανικών ΠεριβάλλοντοςAnastasiadou_Alexandra_MSc_2020.pdfChania [Greece]Library of TUC2020-09-02application/pdf4.3 MBfree Anastasiadou Alexandra Αναστασιαδου Αλεξανδρα Kolokotsa Dionysia Κολοκοτσα Διονυσια Lazaridis Michail Λαζαριδης Μιχαηλ Xekoukoulotakis Nikos Ξεκουκουλωτακης Νικος Πολυτεχνείο Κρήτης Technical University of Crete Passive radiative cooling
