Which Is Greener?

Green is gold in the eyes of many marketing departments. As a result companies are changing their names to include the word “green.” The color green is splashed onto literature, business logos, and websites in an effort to re-brand company and product images so that they align themselves with the energy conservation movement. While conservation is viewed as the right thing to do, not all industries are doing the right thing when it comes to marketing their products.

There is no arguing that windows are one of the largest contributors to heat gain and heat loss in a building’s envelope. Excessive heat gain contributes to the cooling load and under performing glass can have a profound affect on the energy efficiency of a building or a home. So what does the marketing department of your regional window company tell you to do? Go green man! Replace those windows and upgrade to energy efficient performance glass, do the right thing, save money, save energy, and help to preserve the environment.

So is this the greenest solution? Well consider that it takes more than ten times the amount of energy to produce a piece of performance glass (this does not include the energy and resources needed to produce the framing unit) than it does to produce enough window film to cover the same opening. In addition to this consider that the old windows need to be removed, thrown into a landfill where the unrecycled plate glass sits in state forever.

Window film can reject up to 80% of the Total Solar Energy increasing the performance of your existing windows without having to re manufacture new glass. When compared to removal and replacement, window film is the much greener solution of the two choices. If your goal is to LEED Certify your home (LEED EH) or existing building (LEED EB) window film can get you up to 6 LEED credits towards your project by using window film as the greener alternative.
