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.

Infrared analysis shows insulation gaps | Evergreen Home Performance | Maine

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 testing shows air leakage | Evergreen Home Performance | MaineBlower-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 needs to engineer efficiency upgrades - like air sealing in your basement or insulation in your attic - that will meet your goals for comfort, efficiency, and safety.
