Save Energy with a Thermal Imager

Most of the energy our homes use is spent heating and cooling the air to a comfortable level. By some estimates, 50-70% of energy is used on HVAC systems.

So, one of the best ways to cut energy use is to add insulation and seal any cracks in the home. But, how do you identify where insulation is needed, or where a draft is sneaking in? Rather than use subjective means, it’s now possible to use a Thermal Imager to spot energy leaks. That way, you can apply insulation and caulk in only the places where it’s really necessary, and you can limit the use of more expensive housing improvements to the places where they’ll do the most good! Here’s an example of what a leaky door looks like:

If you don’t have a thermal imager hanging around in your closet, your friends may have one you can borrow. Alternate places to check include your local fire station, housing association, or community college. Many such organizations have equipment available for check out or rental. If nothing else, you can buy a camcorder with a thermal function from an electronics store, use it for an energy audit, and then pay the restocking fee to return the camcorder. Not that we recommend such shifty behavior, cheapskate.
