ECO GLASS COMMERCIAL ROI
Although Commercial Glaziers will have different cost structures and mark-ups on the materials they buy, the following examples will demonstrate the potential return on investment for installing energy efficient ECO GLASS / HM windows.
Heat Mirror Glass vs Conventional Double Glazing
Glass: 31,000 sq ft
The payback was immediate and created significant annual energy savings.
High School, Pennsylvania
Heat Mirror Glass vs Low-E Glass
The High School in Pennsylvania weighed the difference between installing Low-E Glass or ECO GLASS HM. When the savings on the HVAC system were factored in, the annual energy savings created a return on investment of 6.49 years. Plus on-going energy costs and savings will be realized after the payback period is completed.
Empire State Building
The Empire State Building is retrofitting its 6,500 windows as part of a total program to generate energy savings. They selected an ECO Glass style of insulating glass with Heat Mirror. Glass performance will be "tuned" based on builidng exposure. An R-5 Glass and an R-8 Glass were selected both filled with krypton to create two super-insulating cavities. Heat Mirror film selection will optimally manage solar heat gain and reduce demands on the heating and cooling system. (Improving window performance was identified as one of eight key projects to achieve the total energy savings goal.)
Heat Mirror technology’s 30-year track record of proven reliability was a critical factor in its being selected for such an iconic building retrofit.
