How to prepare – Energy Loss Survey
Here’s what we’ll need:
1) A clear walking path through the house. Since the floor generally makes up part of the thermal
envelope, we’ll be scanning as much of it as we can see. It’s up to you how much furniture you
move, but we’d recommend you just clear the floor of clutter and leave the furniture where it’s at, with
the exception of exterior walls – see #2.
2) Clear line of sight to all exterior walls. Since a thermal imager can’t ‘see through’ anything,
please remove pictures and paintings from exterior walls. Again, it is up to you how much furniture
you move, just know that if we can’t see the wall, we can’t scan the wall.
3) Access to the electrical panel
5) Access to all doors and windows
6) Access and clear line of sight to any wall or area that you specifically want scanned.
7) If you have small children, consider a baby sitter. (see the What to Expect section)
8) Please have all pets secured or removed. We may use a blower door which includes a large
noisy fan and is not pet friendly.
9) A good temperature difference between inside and outside. Depending on the time of year and
the weather forecast, you may be asked to turn up your heat or air conditioning for several hours prior
to the scan to provide more contrast between the interior and exterior temperature.
10) We will provide a full-color, comprehensive report, but feel free to have a pen, paper, post-it
notes or digital camera on hand for your own reference
What to Expect
When we arrive, we’ll ask a few questions to help us determine the thermal envelope of your home.
Once we know where the envelope boundaries are, we will use a hand-held thermal imager to scan
all the surfaces of the thermal envelope (usually consisting of the exterior walls, floor, and ceiling).
As we find exceptions (i.e. thermal patterns that indicate a potential issue) we’ll record the images. If
we find an exception that appears to be water infiltration, we can confirm with a moisture meter at
your request.
We may utilize a blower door to exaggerate the insulation deficiencies. If we do, we will need to
close and lock all exterior doors and windows. We’ll also need to open all interior doors, so if you
plan to use a spare bedroom for baby-sitting or to keep a pet in, you should make other
arrangements. You need to be aware that the fan used with the blower door is noisy and could be
frightening to small children. We highly recommend that small children be kept at a baby-sitters
house during the survey.
Once we’ve scanned the thermal envelope, we’ll do a quick scan of your electrical panel to check for
potential fire hazards. We’ll then scan any specific areas of concern you may have and attempt to
answer any questions you may have. Depending on the size of your house, an Energy Loss Survey
should take about one to three hours. Within 5-10 business days, you will receive a full-color,
comprehensive report that will include infrared images of all exceptions we found as well as any
recommendations we may have.
