On the cooling potential of cool roofs in cold climates: Use of cool fluorocarbon coatings to enhance the optical properties and the energy performance of industrial buildingsOn the cooling potential of cool roofs in cold climates: Use of cool fluorocarbon coatings to enhance the optical properties and the energy performance of industrial buildings Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-042014enRejection of solar gains is the aim of passive cooling strategies in any type of building and any climatic region. The extent of cool materials’ applicability depends on the external climatic conditions and internal heat gains. The aim of the present paper is to analyse the contribution of an innovative cool fluorocarbon coating in the reduction of energy demand for cooling when applied in an industrial building with increased heat gains under temperate climatic conditions. The material is tested using accelerated weathering procedures and its optical properties, i.e. solar reflectance and infrared emmitance are measured. There is an increase of 120% of the roof's albedo by the application of cool material. Regarding the heating and cooling loads there was a decrease of 73% for cooling while there was a minor heating penalty of 5%.Δημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/Energy and Buildings69417–425 Mastrapostoli Elena Karlessi Theoni Pantazaras Alexandros Kolokotsa Dionysia Κολοκοτσα Διονυσια Gobakis Konstantinos Γομπακης Κωνσταντινος Santamouris Mattheos Elsevier Cool materials Fluorocarbon coating Industrial building Temperate climatic conditions
