A new study, carried out by the Dutch institute TNO for the industry association Glass for Europe (formerly GEPVP – Groupement Européen des Producteurs de Verre Plat), which brings together Europe’s four main producers of building and automotive “flat glass” products, shows that proper application of “solar control glass” technology could cut CO2 emissions in Europe by anywhere between 15 and 80 million tonnes per year. But policies to encourage or mandate the environmentally optimal use of this technology remain to be adopted. According to the association’s press release, solar control glass reduces solar heating of air-conditioned buildings by sending the sun’s heat back out and away from the building instead of letting it through. By significantly reducing the load on air-conditioning systems, it saves large amounts of energy.
