Abstract

This invention relates to various methods for using a thermal imaging apparatus to inspect exterior and interior residential components. In particular these methods can be used to detect mold, electrical problems and moisture in EFIS residential building components.

Claims

1. A method to inspect an exterior component of a residential building containing EIFS for moisture wherein said exterior residential building component is selected from the group consisting of wall, eave and facia under certain weather conditions, by obtaining at least one temperature profile;

comprising step of;

elevating the interior temperature of said residential building to a degree to facilitate contrast of the at least one temperature profile;

obtaining said at least one temperature profile of the exterior residential building component; and

assessing said at least one temperature profile of the exterior residential building component for a thermal anomaly indicative of moisture, wherein the weather conditions at the time of inspection include low wind and temperature of greater than 45°

F. at said exterior of said residential building.

2. The method of claim 1 wherein the step of elevating the interior temperature of said residential building occurs for at least 45 minutes prior to obtaining said at least one temperature profile.

3. A method to inspect an exterior component of a residential building containing EIFS for moisture wherein said exterior residential building component is selected from the group consisting of wall, eave and facia, comprising the steps of:

applying heat to said residential building components; and

obtaining at least one temperature profile of the exterior residential building component; and

assessing said at least one temperature profile for an anomaly indicative of moisture in said exterior residential building component.

4. A method to detect a electrical problem with an electrical circuit in a residential building by obtaining temperature profile comprising:

turning on substantially all light switches in said residential building;

turning on substantially all exhaust blowers in said residential building;

obtaining temperature profiles of substantially all electrical outlets in said residential building; and

assessing each of said temperature profiles for an anomaly indicative of an electrical problem.

5. The method of claim 4 wherein said electrical problem is a faulty connected circuit.

6. The method of claim 4 wherein said electrical problem is a faulty switch.

7. The method of claim 4 wherein said electrical problem is a nonworking component.

8. A method to locate the source of mold growth in a at least one interior building component of a residential building having an interior and an exterior, comprising the steps of:

creating a temperature differential of greater than 10°

F. between the interior and the exterior of the residential building;

obtaining at least one temperature profile of the at least one interior building component;

assessing said at least one temperature profile for a thermal anomaly indicative of moisture; and

identifying the location in said interior residential building component of said thermal anomaly indicative of moisture.

9. The method of claim 8 further comprising the step of:

sampling said location for a mold sample.

10. The method of claim 9 further comprising the step of testing said mold sample for a mold species.

11. The method of claim 9 further comprising testing of said mold sample for a mold spore level.

12. The method of claim 8 wherein one of said interior residential building component is carpet.
