Substituting normal glazing with solar control glass could lead to a reduction of CO2 emission in the construction sector of between 5% to 25% with regards to the famous European 20/20/20 goal.
Various studies have demonstrated that there is a simple and economic method to safeguard the environment: substituting normal glass in windows with solar control products.
European construction standards are now close to those of the US, where 65% of residential buildings and 80% of commercial ones have air conditioning systems installed. If we consider this data in the Mediterranean area, this figure reaches about 100%.
The constant use of solar control glass where there are already air conditioning plants could lead to a reduction of CO2 emission in the construction sector of between 5% to 25% with regards to the famous European 20/20/20 goal.
And, in some cases, the use of solar control glass could even eliminate the need to install air conditioning in some buildings and areas.
According to recent data regarding Italy, 66,534 terajoule of energy could be saved if solar control glazing were to be used both in new constructions and in retrofits by 2020.
This would mean 4523 Kt less CO2 emissions, equal to a reduction of 27.4% of CO2 by 2020, without having to put into practice systems that cause problems to citizens, such as Sundays with bans on private traffic.
If we consider the most recent governmental measures and the continuation of tax benefits regarding energy savings until the end of this year – increased to 65% – for those who change their windows to solar control glazing, these become advantageous for all.
NSG Group, present in Italy with Pilkington products, has a wide range of solar control glazing, from coloured coated glass that can be processed easily by glassworks, up to the more sophisticated types that combine solar control and thermal isolation (also in the self-cleaning version) in just a single sheet of glass, reaching the highest levels of energy efficiency.
