A massive benefit to window films is the money you will save on your energy bills. As a facilities manager, in whatever capacity, finding ways to save money through the improvement of your building is a win-win situation. One area to achieve savings will be through the improvement of your windows. Here is how much energy savings you can expect with new solar window film in Gaithersburg, MD.
How Window Films Save Money on Energy Costs
First, let’s quickly talk through the science of how window films can save money on energy bills. As you’re probably aware, windows are one of the largest culprits of heat gain and heat loss. Solar window films filter out the infrared radiation from sunlight: this is the part of the sunlight which causes heat. Simultaneously, window films also add a layer of insulation helping your HVAC system better maintain internal temperatures.
What Factors Affect Window Film Energy Savings?
First, it’s important to note, the amount of savings you will see is going to be largely dependent on your building. Some factors which will affect the average energy savings and payoff period are:
- Percentage of windows you have on your building compared to walls.
- The location of your building (Southern US vs. Northern US).
- The types of windows you have (single pane, dual pane, tinted)
- The type of commercial window film you install.
With these variables in mind, it’s hard to give an exact number for your specific location and building without doing a complete energy audit. That said, we have a lot of data collected by the top manufacturers of window films which allows us to show you the rough savings you could expect in a small office building or a large commercial building in Gaithersburg, MD.
