Low-E Glass Can Dramatically Reduce CO2 Emissions
The “odometer” above has been running since January 1, 2008, calculating how many pounds of carbon dioxide would not be emitted into the air if all of the low-e glass that PPG produces each year were used in buildings and schools across the country.
The annual production capacity of PPG’s high performing solar control low-e glass has the potential to reduce the energy consumption of buildings by 583,000 Kwh and 44,000 therms per year. That translates to an energy related reduction of 5,326,000,000 lbs of CO2 per year. The energy and commensurate CO2 reduction is based on use of PPG low-e glass in a prototypical eight-story office building model averaged through a full year of actual weather in 12 North American cities.
We can calculate the savings above because PPG Performance Glazings recently commissioned a study by the Architectural Energy Corporation comparing the energy performance of four of the most popular low-e glasses to dual pane tinted glass and several other commonly specified high-performance architectural glasses. The study results showed that, depending on the size, type and climate of a prospective building, Solarban 70XL glass can reduce a facility’s CO2 emissions by thousands of tons over its lifetime. Solarban 70XL glass also has the potential to save as much as $400,000 in upfront capital cooling equipment costs and can produce annual energy savings of up to 13 percent or $97,000 depending on a building’s geographical location when it is specified instead of competing products.

Fast Climate Facts
- As the single largest contributor to global warming, buildings account for approximately 48% of total annual U.S. energy consumption.
- By the year 2035, three-quarters of the built environment in the U.S. will be either new or renovated. This transformation of the built environment represents an historic opportunity to dramatically reduce the Building Sector’s CO2 emissions.
- If every existing building in the U.S. had PPG’s super-performing Solarban 70XL low-e glass, and if every new building were built with it, the U.S. would save 2.134 trillion BTUs, which is the equivalent of 80 power plants and realize $38.4 billion in energy savings.
- If every existing building in the U.S. had PPG’s super-performing Solarban 70XL low-e glass, and if every new building were built with it, the U.S. would reduce CO2 emissions by 123 million tons per year, which is the equivalent of 8.3 million acres of pine forest – four times that of Yellowstone National Park.
