Going Green with Glass

The National Fenestration Rating Council or NFRC is a independent rating agency that we look to in the glass industry for energy performance. Energy performance or energy efficiency is actually something that we are interested as our society shifts to be “Green” and environmentally aware.

How do windows affect the environment? The NFRC provides a very important statistic,”According to Lawrence Berkeley National Laboratory (LBNL), the energy lost through windows represents four to five percent of total annual U.S. energy consumption at a cost of $50 billion” Having efficient windows has a twofold benefit. Not only will it save you money with heating and cooling costs but also allows the consumer to take a more active role in reducing their consumption of utilities.

From a scientific stand point, the NFRC looks at U-values and SHGC among other things. U-value represents thermal performance. In action, the u-value would represent the ability of your glass to insulate the inside (your home) from the outside elements. This would directly affect the users dependence on utilities to control inside temperatures. The lower the U-value, the better the glass system is at insulating heat. The SHGC or Solar Heat Gain Coefficient represents the solar radiation that enters through the window system. Just like with the U-value, we are looking for the lowest number possible.

Currently, Smartglass is preparing for NFRC testing, to better service the the customer. Energy efficiency is one of our concerns, but having customers who are informed is the most important thing. We want you to know exactly what you are getting with our products. We strive to make a quality product and we are confident that NFRC testing will confirm our elevated belief in what we produce.KEL_2574
