A Comparison of Energy, Economic and Environmental Benefits of Transparent Low-E Glasses

In November 2005, PPG Performance Glazings  introduced Solarban 70XL glass, a transparent,  coated solar control, low-emmissivity (low-e)  architectural glass with superior solar control characteristics.

Recently, PPG commissioned a study by the  Architectural Energy Corporation (AEC) comparing  the energy performance of Solarban 70XL  Glass to dual pane tinted glass and several  commonly specified high-performance architectural  glasses. The study showed that, depending  on the size, type and climate of a prospective  building, Solarban 70XL glass has the potential  to save architects and building owners hundreds  of thousands of dollars in upfront capital cooling  equipment costs when it is specified instead of  competing products. Solarban 70XL glass also  can produce annual energy savings of up to 13  percent.

Finally, and perhaps most importantly for  environmentally-focused architects, the study  also showed that the specifying Solarban 70XL  glass for a typical commercial building can  reduce CO2 emissions by thousands of tons  over its lifetime.

This following paper summarizes the energy and  environmental performance of Solarban 70XL  glass, dual-pane tinted glass and other commonly  specified architectural glasses with similar  aesthetic qualities. It also quantifies the potential  cost savings Solarban 70XL glass can provide,  as well as the positive impact this glass can have  for architects seeking to reduce the carbon  footprint of their buildings.
