– Significantly reduce unscheduled power outages– Detects problems quickly, without interrupting service– Assess priorities for corrective action– Minimize preventive maintenance and troubleshooting

time– Improving Equipment Reliability & Life– Check for defective equipment while still under

manufacturer warranty.

Air Leaks

The camera does not “see” air, but it does see the

cooling effect of the cold air on the surface of nearby

materials

Important Notes

– Infrared inspection requires a sufficient difference in temperature from inside to outside (ΔT of 10°C) for a sufficiently long period of time, to produce discernible differences between areas with studs and areas that may contain insulation.

– Wet materials retain heat and change slower than dry areas of the same type building material.

– Knowledge of building construction is necessary to properly diagnose the problem.

Use IR thermography in conjunction with:– R-Value calculator and energy savings estimator– Dew point and wet spot location– Blower door testing– Duct leak testing
