ITI ENERGY SURVEY SCOPE OF WORK

Richardson Home Inspections will perform a non-invasive infrared thermal imaging scan to measure the temperature and temperature differences or variations of the visible, safely accessible, and readily accessible portions of the following:

	interior and exterior walls
	interior ceilings and floors

This survey includes evaluation for areas where temperatures are consistent with missing, non-uniformly distributed, marginal, or wet thermal insulation as well as an evaluation of the overall building envelope including air infiltration and heating and cooling losses from HVAC systems.

The results of these evaluations will be documented the ENERGY Survey Report and will be accompanied by both natural (visible light) and infrared photographs where applicable. Only the visible, safely accessible, and readily accessible portions of the components specified in this scope of work shall be examined and evaluated.

Example #1: The above Thermogram and associated digital image were taken from inside a home and shows a basement walkout entry. The Thermogram shows a large area that is "cooler" (blue/purple hue) than the surrounding area. The thermal patterns are consistent with air infiltration and a large amount of cool air is seeping under the door sweep. This contributes to a significant amount of energy loss!

Example #2: The above Thermogram and associated digital image were taken from inside a home and shows an upper ceiling/wall intersection in a second floor hallway. The Thermogram shows a large area that is "warmer" (orange/yellow hue) than the surrounding area. The thermal patterns are consistent with leaky ducts. It was determined that the distribution ducts above this area were poorly insulated and leaking at seems. Again, this contributes to a significant amount of energy loss!

Example #3: The above Thermogram and associated digital image were taken from inside an unconditioned attic space. The Thermogram shows areas that are "warmer" (orange/yellow hue) than the surrounding area. The thermal patterns are consistent with leaky ducts. Warm air is being lost inside the unconditioned attic!

Example #4: The above Thermogram and associated digital image were taken from inside a home and shows an interior wall in a bedroom. The Thermogram shows areas that are "cooler" (blue/purple hue) than the surrounding area. The thermal patterns are consistent with leaky ducts. This home had undergone some renovations and the duct legs behind this wall were terminated and sealed off. Obviously, they were not sealed adequately. The thermal image clearly shows that cool air is dispersing out from the end caps and into the wall cavity. Again, this contributes to a significant amount of energy loss!
