CRAVEN COUNTY -

On a cloudy and windy day, a house on Metcalf Street in New Bern is warm on the inside, but Tim Broderick uses his thermal infrared camera to see where the heat is getting to the outside.

"This camera reads only temperature," said Broderick.

Every colored pixel on the thermograph, a display on the camera is a degree of temperature.  As Tim walks around the perimeter of the home, he finds the obvious cracks and gaps that are letting the heat out.  It's the little imperfections in an older home that add up to higher heating costs.

"All those little tiny crack and crevices where air can leak is the equivalent to leaving the front door open or even a big window," said Broderick.

On the outside Broderick looks for warm air leaving the home which shows up as a bright yellow color on the camera.  On the inside, Broderick looks for cold air entering the home which show up as a dark blue or purple.

The thermal camera shows architect, like Sarah Afflerbach, what she cannot see or feel on the inside of the home.

"Things that surprised us were that the bathroom fans were really drawing out a lot more air than we thought they would.  We also found some duct work up in the attic that was leaking a lot more than we thought it would.  We actually saw it glowing," said Afflerbach.

The camera shows the yellows and blues so you can save more of the green.
