• Commercial buildings consume 18 percent of the country's energy and 36 percent of its electricity.¹
• 53 percent of existing commercial buildings have single-pane glass and 65 percent is clear, uncoated glass.¹
• Today, 50 percent of glass for commercial buildings has energy-efficient coatings.¹
• Use of spectrally-selective coated glass can reduce lighting and HVAC energy consumption by more than 25 percent.²
• Changing single-pane, clear, uncoated glass in a typical south-facing Chicago building to double-pane, tinted glass with high-performance coatings would decrease energy use by 25 percent with no other changes to the building.¹
• Proper window selection/design can cut peak electricity and cooling loads, thereby avoiding costly peak demand charges, reducing chiller and HVAC systems and costs, and easing the need for new power plants.²
• LEED buildings command rent premiums, higher occupancy rates, increased sales prices.³
• LEED buildings use 25-30% less energy.⁴
