“Going green” has become a frequently used expression in the last couple years. Everyone is doing what they can to be more earth-friendly these days. But, “going green” isn’t just good for the earth; it can be good for your finances too. For example, changing over to a solar system for electricity frees you from the ever-increasing electricity rates that utility companies charge. The federal government has also placed a 30% federal income tax credit on residential solar systems.

In addition to tax credits for going solar, there are some available for a variety “green” house modifications. Tax credits can be claimed for energy improvements to homes, such as windows, insulation, and envelope and duct sealing. Below is a list of the other modifications homeowners can make to receive these credits:

• Adding insulation to walls, ceilings, or other part of the building envelope that meets the 2009 IECC (& supplements) specifications.
• Replacing windows and skylights, and exterior doors which are equal to or below a 0.30 U factor and a Solar Heat Gain Coefficient (SHGC) of 0.30.
• Sealing cracks in the building shell and ducts to reduce infiltration and heat loss - these should be sealed so as to be consistent with the 2009 IECC.
• Window films certified by the manufacturer that the product meets the requirements of a “qualifying insulation system.”
• Pigmented metal roofs, or an asphalt roof with cooling granules must meet Energy Star requirements.

In some cases, taking these measures will not only help you save money, but your health may benefit as well. For example, most homes built before 1980
contain asbestos. Asbestos was used widely throughout the 20th century for a number of things, but it was mainly used for insulation due to its fire-resistant qualities. Unfortunately, exposure to asbestos is the only known cause of a rare and aggressive type of cancer known as mesothelioma. This type of cancer typically forms in the lining of the lungs and is very difficult to treat effectively. This is because mesothelioma symptoms don’t usually show up until about 15 to 25 years after exposure.

There are a number of other alternative types of insulation that can be used that are more eco-friendly than asbestos and don’t pose any danger to your health. The United States Department of Energy has a list of insulation “Energy Savers” you can use when making plans to remodel your home.
