A home energy audit is the first step to assessing how much energy your home consumes and to deciding what measures you can take to make your home more energy efficient and comfortable with measured potential for rebates.
Attic & Crawlspace Air Sealing
Air sealing sounds exactly like what it is, sealing cracks and openings in your building envelope to reduce drafts and cold spots, improving comfort and health. The recommended contemporary strategy with new building standards are to reduce air leakage as much as possible and to provide controlled ventilation as needed. Humidity, pollutants, allergens, soil gasses, and unconditioned air enters through the crawlspace and exits through the attic due to “stack effect” (make it a hyperlink to definition) in homes. That is why air sealing your crawl space or basement, and attic is so crucial to health and energy efficiency within your home.
Insulation is one of the most important building materials in your home, if done properly. Proper insulating can ensure maximum home energy efficiency by reducing heat flow and heat loss. The primary purpose of insulation is to aid in keeping your home's interior conditioned space at the desired temperature, while also reducing the amount of energy used. Insulation creates the thermal envelope of the home, crucial for distinguishing and controlling energy in conditioned spaces from unconditioned spaces.
Utility and appliance upgrades are some of the biggest ways you can save on your energy bill, and increase the resale value of your home. During your energy audit, the appliances and utilities will also be tested for safety, longevity, and current efficiency as compared to a Energy Star model of the same nature. According to the U.S. Environmental Protection Agency (EPA), efficient appliances use 10 to 50 percent less energy and water than standard models.
In homes with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In the average house, however, roughly 20% to 30% of the air moved through the duct system is lost due to leaks, holes, and poor connection points. That results in higher utility bills and a difficult time keeping the house comfortable over time. Loose ductwork can also invite allergens and pollutants into the HVAC system by negatively pressurizing unconditioned space, they are commonly installed in. Duct sealing is the application of air tight mastic or aero-sealing fibers at these weak points of the duct system to create a tight, closed in duct work assembly where applicable.
