| Abstract | It is well known that the building sector significantly contributes in the percentage of total consumption of energy and to associated environmental impacts such as greenhouse gas emissions, toxic air emissions, etc. Consequently, the reduction of the cooling and heating energy consumption in buildings is both of environmental and economical concern. Advanced glazing can have a significant role towards this direction. According to the presented analysis, the building energy consumption can be reduced by 55% when the electrochromic device is used in cooling dominated areas. More than 30 MJ are saved per MJ consumed during its lifecycle, the corresponding CO2 emissions reduction is more than 500 kg CO2 equivalent, while the reduction of toxic emissions can reach 45 kg 1,4-DCB equivalent, when the lifecycle is extended to 25 years. If the lifecycle is extended above 20 years and the device price is reduced to 200 €/m2, each MJ saved would cost less than the current electricity price in Greece (1.07 cent/MJ). The above results indicate the high environmental performance of the EC glazing, their environmental benign nature and enhance their use as energy saving devices adjusted to the building envelope. |
