What You Need to Know About Home Energy Evaluations

If you’re like most homeowners, you probably suspect that energy is being wasted in your home. Yet, unless you know how and where it’s being lost, you can’t prevent it. Fortunately, professional home energy evaluations can quantify and identify energy waste. While you might be able to perform a basic do-it-yourself energy evaluation yourself, a professional audit is a more comprehensive way to minimize energy inefficiency.

What to Expect in an Expert Home Energy Evaluation

The energy auditor will tour your home, examining windows, doors, walls and roof; checking for insulation; inspecting ductwork, and taking a close look at your heating and cooling system. He or she will likely review recent years’ utility bills to develop a picture of your family’s energy use. Diagnostic tests, using high-tech imaging equipment, will be undertaken. These include the blower-door test. A powerful fan is installed in an exterior doorway and turned on to blow outside. This is done after all windows and doors are closed. The auditor will use a gauge to measure how quickly the interior air pressure returns to normal after all the air has been sucked from the home. While this is happening, a thermographic scan will show where air …

Want to Perform a Home Energy Evaluation? Use this Checklist

For homeowners who want to save money on their monthly energy usage, a home energy evaluation is an excellent first step. This type of evaluation shows you where you are using or losing energy and gives you the opportunity to correct problems that can drive your costs up.

Check the insulation: Insulation keeps warm air inside during the winter and outside during the summer. Check your walls, ceilings, floors, foundation, attic, and basement for the proper amount of insulation. Pay particular attention to the attic and uninsulated areas such as crawl spaces. Substantial amounts of warm air and energy can be lost in those spots. Look for air leaks: When warm air leaks out of your home, you’ve not only lost air you’ve already paid to heat, you also have to pay for more air to make up for the loss. Find any areas of air loss and seal them. Look around doors and windows, at points where pipes or wires enter your home through the wall, and at spots where the foundation and attic floor contact the frame. Caulk holes, cracks, and gaps to seal them. Check the ductwork: Air loss in the ductwork of your heating or cooling …

A Home Energy Audit – Best Way to Gauge Your Home’s Efficiency

 A Home Energy Audit - Best Way to Gauge Your Home

Energy bills are very effective for tracking energy usage and costs, but they won’t tell you where your home is wasting energy. A professional home energy audit is a sensible tool to locate energy leaks, and make your home more energy efficient, comfortable and pocketbook friendly.

Home Energy Audit

A home energy audit is a series of tests and evaluations that assess how much energy a home uses, how and where the energy is being used and/or wasted, and determine where energy consumption and waste can be reduced or eliminated. The following summarizes the areas and systems that are evaluated during a home energy audit, the equipment used and the process:

Insulation barrier — Home insulation hinders heat exchange between the living spaces and the unconditioned spaces, such as the attic, exterior walls, and the basement or crawl space. A thermographic scan detects heat loss/gain through the home shell, which indicates lack of insulation or damaged and ineffective insulation. Air leakage — A blower door test is used to pressurize or de-pressurize the home in order to locate air leaks. Common …

The Blower Door Test: A Key Component of an Expert Home Energy Evaluation

The Blower Door Test: A Key Component of an Expert Home Energy Evaluation

A professional energy evaluation of your home could be the first step in improving the energy efficiency of your home. These evaluations include a blower door test, an assessment that pinpoints how much and where you home is leaking air (or allowing it to infiltrate). Although it’s possible to conduct your own energy audit by looking for air leaks, the professional audit will turn up those areas where air leaks occur in less obvious places.

The blower door frame and fan adjusts to fit tightly inside most exterior door openings. It contains a large, variable-speed fan that pulls the air out of your home, along with gauges that measure the falling air pressure as air is removed. Once the technician has readied your home for the test, he or she turns the fan on and uses the gauges to note how long it takes to drop the air pressure in your home to 50 Pascals.

Homes that have few air leaks lose pressure quickly, while a structure that has leaks takes longer to lose pressure. The fan in the door is powerful, and it will result in air rushing back into the depressurized house through even the smallest cracks. Likely …

After Your Home Energy Audit: Deciding on Your Efficiency Improvements

After Your Home Energy Audit: Deciding on Your Efficiency Improvements

Congratulations – you’ve had a home energy audit done for your house; you conducted it yourself, or else paid a professional HVAC specialist who knows all the important diagnostics tests. You now have a list of things that must be fixed, and you’re no doubt wondering where to start and how to prioritize your pending home improvements. With the heat and humidity of a Georgia summer upon us, here are some suggestions that will help you decide how to begin:

Consider your budget first. Do you have the money/resources to handle everything on the list, or can you only afford one thing at a time? Focus on the improvements that will save you the most money while being relatively simple to put into effect. As long as your HVAC equipment is functioning, regardless of the season, make insulation and air leakage your priorities. Air leaks can account for as much as 30 percent of your energy bill. Use spray foam, caulk and weatherstripping to seal windows, doors, switch plates, the junctures of walls and ceilings, electrical outlets, baseboards, and window/wall mounted air conditioning units. This includes places where a wire or pipe enters your house, and all vents as well. …
