Improve comfort, reduce humidity and save money!

Is an energy audit worth it?

Should an energy audit be done when purchasing a new home?

What's the difference between a home inspection and an energy audit? 

How can we reduce the greenhouse gas emissions from our home?

A home inspection is simply that - and is in place to ensure a home and its components are in working order.
An energy audit however, tells you how efficiently the components are working, your energy consumption and how and where to make wise improvements. Energy audits are very helpful when you purchase a new home to get an overview of performance of your home overall. An audit report is something you can reference for years as you renovate or upgrade HVAC equipment over time. Learn about the parts of your home you cannot see as these are the elements that impact comfort, indoor air quality, durability and the environment.

At Priority Energy, we utilize our building science expertise to evaluate every aspect of a home, since one component will affect the performance of everything else. Our BPI and RESNET certified energy auditors are specialists at detecting the visible and not-so-visible areas where your home is wasting energy.  When less energy is used or less energy is wasted, fewer carbon emissions are released into the air. We have helped thousands of people save money and make their living spaces more energy efficient, more comfortable and healthier.

What Does a Home Energy Audit Include?

The Comprehensive Energy Audit 

Priority Energy's energy auditor will begin by understanding your goals for the audit; ie. reduce utility costs and energy consumption, improve energy efficiency, increase year-round comfort, improve indoor air quality and home health, diagnose high humidity issues, solve recurring ice dam problems, reduce your carbon footprint, etc. 

We begin with a short interview so we can get to know you and your household (because no two homes are occupied and used in the exact same way.) A history of the home, such as renovations, HVAC equipment, roof, siding or insulation is very helpful to know as changes in these components can have a big impact on performance.  

The audit inspection will include:

    1. A visual inspection of the home’s exterior envelope. We look for points of air leakage, moisture or water damage, drainage or gutter problems, and any signs or symptoms of a compromised "shell".  
    2. A blower door test (to simulate worst case air leakage scenario) combined with an infrared analysis will show us air leakage points, insulation deficiencies, hot and cold spots and duct leaks. 
    3. A room by room inspection during depressurization with the IR camera.
    4. A comprehensive review of your HVAC equipment to include static pressure testing, fan flow rates, and temperature rise. We make sure your is properly set up for safety and efficiency. Ventilation is also evaluated for healthy indoor air quality.
    5. A duct leakage test to evaluate the condition of the home's ductwork and to assess if there is heating or cooling loss due to leaks or breaks in the system. 
    6. A combustion safety testing to check for health and safety of the indoor air quality.
    7. A review of a year's heating and cooling use (see note about utility bill analysis).
    8. A detailed final report of the home's energy efficiency performance which will include explanations of each item above.  Priority Energy's audits outline improvement recommendations based on a homeowner's goals; ie reducing energy costs or better comfort. The report will show projected energy savings and costs and explain the benefits associated with each item. Photos and infrared images are included for clarity and reference.


What can you tell from our Utility Bills?

It is surprising how much we can learn simply by applying some math to your utility use statements. By separating your utility bills into two categories and using some simple math, we can learn a lot about you and how your home uses energy.  The base load is your hot water, washer/dryer, refrigerator, etc. and the seasonal load is your heating and cooling.  We can even compare how efficiently your HVAC system is operating by comparing your seasonal usage to the seasonal usage of other homeowners in your area.

What is an Infrared Analysis?

Infrared imaging allows us to see leaks around doors and windows, like the dark spots shown in this IR photo. 
The IR cameras help us identify missing insulation throughout the home, any moisture issues, hot and/or cold spots (like faulty wiring), and overall construction details. 

Considering new windows?  Our energy auditors will also analyze your windows to understand the efficiency of their insulation and UV coatings.  This will help to determine the necessity and potential value associated with any window replacements.

What is a Blower Door Test?

The amount of air leakage in the home's building envelope or outer shell is determined by performing a blower door test.
A blower door is essentially a high powered fan that is put in an outer doorway to pull air OUT of the house.  This creates the “worst case” air infiltration condition which allows us to identify air leaks and measure the amount of air your home is letting in and letting out. From here, we can quantify the savings associated with bringing the home in line with nationally accepted air leakage standards. This is measured at a rate of ACH50, or cfm50 per hundred square feet of building envelope.  

What is a Duct Leakage Test?

Priority Energy also performs a detailed analysis of your home’s ductwork to determine if this important internal component is properly balanced and leak free. Air ducts play an important role in the overall comfort of each room in your home and have a major impact on the efficiency of your HVAC system. In addition, a heating and cooling system that is too large or too small can create indoor air quality problems, humidity issues and structural damage.

Why do you test the Mechanical System? And what is a Combustion Safety Test?

The only products of complete combustion are carbon dioxide and water.  If an appliance such as a furnace or water heater is running inefficiently, it will produce inordinate and sometimes dangerous amounts of carbon monoxide and oxygen.

The temperature of the exhaust gas tells us a lot about the efficiency of the HVAC system. If it is too hot, it is wasting energy; if it is too cold, it is probably producing acidic condensation in your vents and chimney, which can cause big problems.  

Priority Energy Auditors use the latest flue-gas analyzers to test the gas and temperature emissions of your combustion appliances.  In this way, we can determine if an equipment tune-up or complete replacement is needed, as well as the associated savings.

Balanced airflow coming in and out of your furnace is essential to achieving optimum furnace efficiency and durability. During the duct test mentioned above, we will check that your system is set up properly and that increased pressure is not being put on your vents.

The Improvement Analysis and Reporting

Comprehensive Energy Audits include a written, detailed report of test results, IR images and a summary of our findings. The report will identify comfort, health and energy efficiency improvements that will bring you the most benefits and their related costs.  It will also tell you where and how you can save the most money. Our customers tell us they use their audit report for years after their energy audit was performed.
