Evaluation of the environmental profile of advanced electrochromic glazingEvaluation of the environmental profile of advanced electrochromic glazing Σύντομη Δημοσίευση σε Συνέδριο Conference Short Paper 2015-11-122005enThe Life Cycle Assessment methodology has been implemented for the environmental evaluation of a prototype electrochromic glazing. Such a glazing can provide significant energy savings replacing a commonly used single glass unit in buildings located in the three climatic areas of Greece. Energy savings up to 5608 MJ per EC unit can be achieved when the EC device is used in cooling dominated areas, in buildings with large facades. This corresponds to cooling and heating savings of 127.1 kWh/m2 glass per year and 94.3 MJ/m2 glass per year respectively. The reduction in building energy needs reaches 55.7% and the energy pay back time is only 0.8 years since the embodied energy represents only 3.3% of the energy saved during its life cycle. The net CO2 emissions reduction is estimated to be 483.2 kg CO2 equivalent, while only 0.8 years of operation are required to compensate the lifecycle emissions. Net human toxic emissions reduction can reach 46.4 kg 1,4-DCB equivalent, compensating its life cycle toxic emissions already from 0.7 years of operation.http://creativecommons.org/licenses/by/4.0/345Glass Processing Days Papaefthimiou Spiros Παπαευθυμιου Σπυριδων Eleni Syrrakou Nikolaos Skarpentzos Panayiotis Yianoulis Tampere Region Glass Cluster
