:036 Thermal Imaging

Suggested Review – none

Today’s 1:5:10:365 Tip for becoming a better steward for our home and planet is about having a thermographic evaluation of your home.

1:5:10:036 Tip: Infra-red thermal imaging is an effective way to scan buildings for missing or damaged insulation, air infiltration, and a variety of other energy wasting conditions.

In order to be most effective the temperature difference between the indoor and outdoor environment should be a minimum of 20 degrees.


Additional Information

The yellow/orange/red area shown on the above home is where heat is escaping from this attic. This scan from the exterior of the home demonstrated something was wrong and adding heat to the attic.

It turned out the source of this heat was leaking furnace system duct-work.

Air with a temperature of 147 degrees was leaking from this partially disconnected duct warming the attic and not the house. Sealing this and other areas of leaking duct-work resulted in a winter time gas reduction of over $100 per month.

The US Department of Energy has recommended that home buyers have a thermal imaging evaluation when performing energy audits and when purchasing a new home. They have additional information at:  http://www.eere.energy.gov/consumer/your_home/energy_audits/index.cfm/mytopic=11200

This is best performed during the cold of winter or the heat of summer when the greatest temperature differences can be observed.

If you are looking for someone to perform a thermal imaging inspection of your home, I have listings for Thermographers on my book blog page at:
