Cedric Janssens looks at how energy efficient glazing discussed in Europe could become a key driver globally as climate change stays top of the agenda and carbon dioxide emissions and energy consumption stay key...This article proposes to consider the impact of the renovation rates on the energy savings and CO2 emissions reduction of one element of the building's envelope; i.e.the windows and in particular their glazing.Based on an assessment of the EU current building and window renovation rates and quantifications in a recent report commissioned by GLass for Europe to TNO(TNO 2019),this paper presents the quantities of energy and CO2 which can be saved by 2030 and 2050 using adequate glazing depending on the building type and location.Four different scenarios are developed analysed for the entire EU-28:two scenarios assessing the maximum/theoretical savings potential of glazing(in 2030 and 2050)and the impact of doubling the EU building renovation rate between 2020 and 2030.Based on thesefindings,this article will reflect on the current renovation trajectories and policies,and how can the reform of the EU cLimate policy help energy efficient glazing contribute to the Paris objective.
