You may be doing just that without even realizing it! If you have skylights in your home and they are not Velux skylights, you should read this because the difference between older skylights and Velux “Fresh Air Skylights” is night and day. Current Velux skylight models have an advanced engineered glass system that can keep the cold and heat out while letting the maximum amount of light in.
Here is the Science
It starts with low-emissivity (Low E3) glass, a unique triple-coated glass capable of reflecting greater solar heat gain without any tinting. In fact, it outperforms tinted glass in heat reflectance as well as fade resistance for surfaces exposed to solar rays. It blocks 95% of the sun’s damaging ultraviolet rays, thus protecting your interior, all while maintaining comfortable temperatures!
The superior insulating capability of Low E3 glass partnered with Velux’s patented gasket system of double-sealed panes, stainless steel spacer bar, and 95% argon gas is a key factor in the construction of efficient skylights – especially in colder climates! Not only does a well-insulated skylight unit keep out the cold, but it can reduce condensation as well. In lab tests, the Low E3 glass maintains an interior surface temperature between 52°-60° while exterior temperatures are as low as -20°! The dramatic comfort improvement from warm glass surfaces means the relative humidity of the indoor air can be controlled and maintained properly. Proper humidity levels (not too much, not too little) will improve comfort and promote a healthier living environment.
Here are the Savings
The natural light that a skylight brings can help reduce your lighting costs. Venting skylights can help homeowners save money on air conditioning costs.
The energy savings attainable with current Velux skylight models is about 35% higher than what they used to be on the dual-pane clear glass models from 1990. If you have acrylic bubble skylights or blackout blinds, the energy savings are even greater!
30% Federal Tax Credit on Solar Skylights
If you have an older, fixed skylight and upgrade to a Solar Powered “Fresh Air” Skylight, you can bring fresh air as well as natural light into your home for an average of just $100* more than a standard fixed skylight after tax credit. A solar powered replacement Velux Skylight and accessories are eligible for a 30% Federal tax credit until 2019, averaging between $330 and $480.* If you add a factory installed solar powered blind to the skylight, the tax credit will cover the cost of the new blind. Since it’s entirely solar powered, there is no need for an electrical connection. When installing a new skylight, the Federal tax credit averages between $540 and $720.*
The Skylight that Cleans Itself
Velux’s Patented Neat Glass Technology helps to keep views clear. A titanium dioxide layer on the Neat Glass reacts chemically with the sun’s UV rays and causes organic materials that are on the glass to decompose. It works even on cloudy days, as 80% of UV radiation gets through cloud cover. When it rains, the decomposed dirt no longer clings to the glass, easily rinsing away!
How the “Fresh Air” Skylight Gets its Name
The Velux “Fresh Air” Skylight is a venting unit, able to open and close just like a window. It can be controlled remotely, so you don’t need to use an extension pole to access it. Velux’s “Fresh Air” Skylight can be solar, electrically, or manually powered.
In solar models, a rain sensor is built in to close the unit in the event of inclement weather while you’re away. A solar panel captures daylight and uses it to recharge the highly efficient, fully concealed battery powered operator system which opens and closes the skylight.
*Savings will vary according to the skylight model, number of skylights, and installation cost. Calculations are based on the estimated costs for both the product and installation. These estimates were generated assuming a typical installation using national averages for construction costs. See the Solar Shade Tax Credit page for more information:
