Your Guide to a Home Energy Assessment

It all starts with a home energy assessment, which provides you with a top-to-bottom look at where your home is wasting energy so you can get to the root of common household problems such as drafts, inconsistent temperatures, and heating and cooling issues. It goes beyond addressing the surface-level symptoms of inefficiency and analyzes how all the elements of your home work together so you can choose the upgrades that will have the biggest impact on your energy bill.  

What to expect: 



1. Exterior Inspection:

A full look at the shell of a home, the water drainage, and condition of the moisture barrier. Visual cracks to the foundation may cause air leakage as well as potential mold growth. We look for any visible PACM or any other potential hazards. Cracks in the homes siding could potentially lead to moisture issues if not handled properly. Most of the time cracks in foundation can be patched and sealed to avoid any serious consequences.


2. Health and Safety Inspection:

We check for any carbon monoxide produced by ovens, boilers and fireplaces and check for gas line leaks while we are at it! We want you and your family as safe as possible. Our certified technicians are geared with the latest technology to ensure accurate results. For example, improper ventilation can cause mold or mildew growth, which you may not discover until it becomes severe and costly repairs are required. An EMS Certified professional can prevent problems before they affect your health or damage your home.

3. Attic Insulation Levels:

EMS will enter the attic or unconditioned locations of the home to assess the condition and depth of your insulation. Often times, especially in older homes in the Northeast, we find the insulation has deteriorated over time due to poor air sealing when the home was initially constructed. We document the levels using rulers and photos while present in the attic space. Typically, after installation, your attic will look similar to the photo on the left.




4. Living Spaces:

We work our way down to your living space, using thermal imagery we assess the wall insulation levels with a state-of-the-art inferred cameras. EMS conducts a thorough visual inspection to check for holes and cracks inside your wall space as well as any unnecessary penetrations. Windows may also lead to a significant amount of heat loss if they are not air sealed properly. Single-pane windows can struggle to retain heat, especially if the sill and molding is not insulated and sealed properly.


5. Basement:

We thoroughly inspect for conditions that may produce hazardous mold or any other airborne toxins. EMS will also check your foundation and drainage in the basement. We will also inspect moisture level at the wall surface for the potential to finish your basement, add value and square footage to your home while insulating and providing energy saving immediately.

6. Boiler Efficiency Testing:

We go into your heating/cooling location and not only test your boiler/furnace, but your hot water tank as well. Using the latest testing equipment we are able to gauge the overall efficiency of the units in place. The technology used will also help determine if any gas leaks are present in the home, sometimes homeowners are not aware of the dangers that may cause by a gas leak.


7. Infrared Imaging:

The infrared imaging will identify and depict inconsistency within the home. The color coded imaging helps determine what sections may be lacking insulation as well as how much of a temperature discrepancy there may be from room to room. Interior scans are more common, because warm air escaping from a building does not always move through the walls in a straight line. Heat loss detected in one area of the outside wall might originate at some other location on the inside of the wall.  These scans are also commonly used with a blower door test running. The blower door helps exaggerate air leaking through defects in the building shell. Such air leaks appear as black streaks in the infrared camera's viewfinder.



8. Blower Door Test:

We like to call this test the Grand Finale. The blower door will pinpoint all the drafty areas and leaks in your home. It depressurizes the home (to a very safe level) and basically accelerates all of the drafts in the home to help identify what could be causing the inconsistency of comfort or high energy bills, or in most cases, both.  This test will also direct us where we need to seal your home in order to maintain a thorough air sealed building shell. We like our customers to be aware of these problems, or in some cases, we like to compliment you on a nice tight home, so we like to bring you around and show you exactly what we find while the test is being conducted. Some of the findings may really surprise you! 


EMS will compile a comprehensive energy report to review our findings with you. We list all of our test results and enter the findings into an energy model which will identify the biggest potential for energy improvements.  EMS is fully staffed with BPI Certified Technicians to carry out the most comprehensive energy upgrades. With highly incentivized state programs it has never been a better time to do these upgrades!
