COMMERCIAL: ROI (Return on Investment)
The return on investment is different for each project but here are a few examples that will help you evaluate the financial part of the ECO GLASS | HM equation while you consider the exceptional comfort benefits.
Remember, Commercial Glazier will have different cost structures and mark ups on the materials they buy.
EXAMPLE 1: Airport, Texas
Heat Mirror Glass vs Conventional Double Glazing
Glass: 31,000 sq ft
| Airport, Texas |
|
| Incremental Glass Cost |
$93,000 |
| HVAC Savings* |
$364,500 |
| Capital Cost Savings |
$271,500 |
| Annual Energy Savings |
$8,000 |
| * 81 tons @ $4,500/ton |
|
The payback was immediate and created significant annual energy savings.
Example 2: High School, Pennsylvania
Heat Mirror Glass vs Low-E Glass
| High School, Pennsylvania |

$114,236 |
Annual Energy Costs |
$43,782 |

|
When the savings on HVAC system were factored in, the annual energy savings created a payback of 6.49 years.

| Marginal cost of ECO-style Glass |
$7,013 |
| Reduced HVAC Costs |
$5,715 |
| Net Marginal Cost of ECO-style Glass |

| Ten-Year Savings |
$16,169 |

Example 4: 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.

ECO | ECONOMICS
If your objective is to create a GREEN BUILDING, ECO GLASS | HM is the only insulating glass that provides the highest insulating values, the most comfort factors, the most LEED points, and generates an excellent return on investment.
