Aluminum Wiring

   Between approximately 1965 and 1973, single-strand aluminum wiring was sometimes substituted for copper branch-circuit wiring in residential electrical systems due to the sudden escalating price of copper. After a decade of use by homeowners and electricians, inherent weaknesses were discovered in the metal that lead to its disuse as a branch wiring material. Although properly maintained aluminum wiring is acceptable, aluminum will generally become defective faster than copper due to certain qualities inherent in the metal. Neglected connections in outlets, switches and light fixtures containing aluminum wiring become increasingly dangerous over time. Poor connections cause wiring to overheat, creating a potential fire hazard. In addition, the presence of single-strand aluminum wiring may void a home's insurance policies. Inspectors may instruct their clients to talk with their insurance agents about whether the presence of aluminum wiring in their home is a problem that requires changes to their policy language.

Asbestos

What is Asbestos?
   Asbestos is a mineral fiber that can be positively identified only with a special type of microscope. There are several types of asbestos fibers. In the past, asbestos was added to a variety of products to strengthen them and to provide heat insulation and fire resistance. InterNACHI inspectors can supplement their knowledge with the information offered in this guide.

How Can Asbestos Affect My Health?
   From studies of people who were exposed to asbestos in factories and shipyards, we know that breathing high levels of asbestos fibers can lead to an increased risk of lung cancer in the forms of mesothelioma, which is a cancer of the lining of the chest and the abdominal cavity, and asbestosis, in which the lungs become scarred with fibrous tissue.
   The risk of lung cancer and mesothelioma increase with the number of fibers inhaled. The risk of lung cancer from inhaling asbestos fibers is also greater if you smoke. People who get asbestosis have usually been exposed to high levels of asbestos for a long time. The symptoms of these diseases do not usually appear until about 20 to 30 years after the first exposure to asbestos.
   Most people exposed to small amounts of asbestos, as we all are in our daily lives, do not develop these health problems. However, if disturbed, asbestos material may release asbestos fibers, which can be inhaled into the lungs. The fibers can remain there for a long time, increasing the risk of disease. Asbestos material that would crumble easily if handled, or that has been sawed, scraped, or sanded into a powder, is more likely to create a health hazard.

10 Ways to Save Energy in Your Home

   Most people don't know how easy it is to make their homes run on less energy, and here at InterNACHI, we want to change that. Drastic reductions in heating, cooling and electricity costs can be accomplished through very simple changes, most of which homeowners can do themselves. Of course, for homeowners who want to take advantage of the most up-to-date knowledge and systems in home energy efficiency, InterNACHI energy auditors can perform in-depth testing to find the best energy solutions for your particular home. 

Why make your home more energy efficient? Here are a few good reasons:

• Federal, state, utility and local jurisdictions' financial incentives, such as tax breaks, are very advantageous for homeowners in most parts of the U.S.
• It saves money. It costs less to power a home that has been converted to be more energy-efficient.
• It increases the comfort level indoors.
• It reduces our impact on climate change. Many scientists now believe that excessive energy consumption contributes significantly to global warming.
• It reduces pollution. Conventional power production introduces pollutants that find their way into the air, soil and water supplies.

Building Permits

What is a building permit?
   A building permit is a permit required for new construction or renovations to existing structures. Local municipalities issue building permits for work that could affect the public’s health or safety, if improperly performed.

How is a building permit obtained?
   In order to obtain a building permit, certain information must be given to the local building official. Intermediate and final inspections may need to be performed by their inspectors to verify that the work was performed in accordance with applicable building codes.
   A building permit may be obtained by the owner or a licensed contractor after filling out a few forms and paying a small fee. Plans and specifications prepared by an architect or professional engineer describing new work or alterations are required for large projects where structural elements are involved, or when major electrical, air conditioning or plumbing systems are altered. Minor alterations may require a permit, but usually do not require plans and specifications.
