Energy Efficiency Audits & Contracting in Coastal Maine
Your Home Energy Audit
When you’re ready to take control of your home’s safety, comfort, and energy use, schedule your home energy audit. We use the latest technology to pinpoint problems and diagnose opportunities to stop heat loss, reduce energy consumption, and improve the comfort and safety of your home.
Walk-through: Every energy audit begins with a thorough assessment of your home, inside and out. We look for common problems based on the age and style of your home, and take photos to document these issues as well as your home’s particular conditions.
Infrared thermography: A thermal reader shows temperature differences throughout your home. We’re looking for any inconsistencies, like warm spots that indicate heat leaking through your home’s foundation, or cold spots that reveal insulation deficiencies.
Blower-Door Test: Your home depends on a slow, steady exchange of air. Too slow, and indoor air quality suffers. Too fast, and you waste energy by heating air that will soon be outside your home. In a blower door test, a large calibrated fan blows air out of the house, depressurizing the space and measuring the airflow through leaks in the thermal envelope. We determine the rate of air exchange in your home and pinpoint leaks that inflate that rate.
Combustion Appliance Testing: Poisonous carbon monoxide gas is a byproduct of all combustion appliances, including fuel-burning furnaces, boilers, water-heaters, and space heaters. We test for carbon monoxide and conduct safety tests to ensure that chimneys, flues, exhaust fans are functioning appropriately.
Other Considerations: We evaluate mold and other air quality issues and suggest improvements to temperature and lighting comfort. This comprehensive assessment of your whole house takes two to four hours, and generates data your Energy Advisor uses to create a computer model of your home’s energy use. Changing certain variables in the model - like the level of air sealing in your basement or the amount of insulation in your attic - helps us predict the energy savings you'll see from your improvement project.
