Perhaps the most significant way to bring down the energy and utility bills while at the same time upholding the comfort of your home is a comprehensive energy audit using the concept of thermal imaging, also called thermography. For as little as $500, carrying out a home energy audit enables you to spot plenty of problems just by simple examination. They can also reveal the exact spots of the invisible energy wasters in your home. Imagine for a second coming across a picture which shows you precisely where in your house a leaking heat is! These cameras also prolong the human vision into the invisible and the infra-red spectrum of light. This is the kind of light which is exuded by objects that are warm. Each object radiates this kind of light. Those objects or areas that are warmer are contrasted with those that are cooler or slightly cooler. Mosquitoes employ this methodology to determine which areas of the body are warmer and which are darker. The doctors, on the other hand, make use of the thermal scanners to find out those areas where the flow of blood is higher and subsequently warmer like the tumors and infections. You can even notice the warm spots where a dog has been lying while on the sofa when you were away even if it wags its tail innocently. This captured the attention of the producers of the Ghost Busters TV show. They do intend to showcase that spirits are indeed visible using thermal images. They normally display the videos using fleeting infrared images. Those images often possess FLIR printed at the corners which are coincidentally the name of most popular camera manufacturers. It stands for Forward-Looking Infrared Radar, which is basically a military of the concept of thermal imaging. This techniques aids in pinpointing specific flaws of energy in your home which lets you channel on your home improvement money where it shall bring about the greatest returns. For example, the work you carried out on your house previously may get compacted, dislodged, or the insulation removed. Thermography has the ability to reveal these areas just as an X-ray can clearly do. These infra-red images also show those areas that are damp because moisture has the ability to alter the insulation properties of any material that is porous. The older houses may even lack any insulation altogether. A more common culprit of energy is the air leaks which arises especially around the doors, furnace, the windows or the air-conducting ducts. Wasteful or harmful electric spots are also visible such as the bad electrical connectivity, overworked motor, or the failing circuit breaker. Given that the most serious energy offenders are often the air leaks, the energy auditor will most often employ a blower fan door to generate a sight vacuum in your home. This door comes basically in the shape of a plastic fabric rectangle which fits an exterior doorway, possesses a fan, as well as a special electronic control to guarantee precise warmth. The vacuum draws in air from the outside or from the many ducts which convey warm or cool air into the house through the many invisible cracks. This air can either warm or cool the surrounding materials whereas the thermal cameras reveal the affected areas. The inspector conducting the audit provides appropriate interpretation of the significance of these leaks. Most energy auditors are increasingly certified in their trades. They also take tests which enable them to make proper use of the various pieces of equipment, interprets the blower door or camera outcomes correctly, and give rise to useful reports. Some of the top certification agencies include Residential Energy Services Network (RESNET), Association of Energy Engineers (AEE), and the Building Performance Institute. Apart from being a useful tool for the improvements of homes, an energy audit is also a fundamental part of the house inspection moments before making a purchase or as a great sales tools for a home seller.
