3 Tips That Boost Energy Efficiency In Your Home

Posted by Paul Wadsworth on Mon, Oct 01, 2012 @ 02:08 PM

Today, the question is not whether to boost energy efficiency in your home, it's how. Almost any house can benefit from a Home Performance Assessment to evaluate the amount of energy waste, track down comfort problems and identify potential safety/health risks. Focusing just on the energy loss component of the Home Performance Assessment (we will discuss the other aspects in future blog posts), a trained building analyst uses specialized equipment to identify the sources of energy loss and suggest options to remedy the situation.

In most cases, heating and cooling energy loss will be traced to air leakage, inadequate insulation and improper equipment maintenance, particularly the ductwork. Air leaks and insufficient insulation account for about 20% of energy loss while unmaintained ducts can lose another 20%.

The most immediate way to boost energy efficiency in your home comes from addressing these three areas:


Air leaks

Tips to make your home more energy efficientWeatherstripped doors and windows and caulked cracks or gaps in walls make a home airtight. Often there are unintended thermal bypasses that allow leaks from indoors to the attic or directly outside. These are not always obvious, but can be uncovered using the diagnostic equipment utilized by an experienced home energy auditor. Heat energy is less likely to seep into the premises during summer and elevate your cooling load and utility bill. In winter, warm air won’t escape outdoors through these openings. An airtight home also maintains the air balance in rooms critical to efficient heating and cooling. 

Insufficient insulation

Insulation on the attic floor keeps the attic's heat from radiating down through your ceiling in summer. During winter, it helps contain furnace heat in living spaces. In the Cleveland area, the Department of Energy recommends minimum attic insulation with an R-value of 49. This translates to a depth of at least 15 inches for fiberglass batts and 13 inches for blown cellulose. The level of insulation inside wall cavities can be evaluated by the energy auditor using an infrared camera. In Cleveland, blown-in insulation inside walls should provide an R-value of 13.

Defective ducts

Many homes have ductwork that leaks up to 20% or more of the air it is supposed to be delivering to the rooms. Conditioned air spills into attics, crawl spaces and other zones where it provides no benefit. An energy evaluation includes a duct pressure test to determine the degree of leakage and pinpoint leaks for permanent sealing.
