Leaky Office Windows
EHSI was asked to do an IR inspection on the top 2 stories of a 3 story office building in the Philadelphia area. Large windows surrounding both floors leaked water badly creating water damage, peeling wallpaper and mold growth. However, the extent of damage was hidden inside the walls. The landlord received remediation estimates over $45,000 just to remove and replace all perimeter interior wallboard after the windows were repaired. In only a few hours, EHSI reduced the scope of work to about $15,000 (a 67% reduction) by precisely identifying the areas of wetted and potentially moldy wallboard. This also saved time and disruption of the office's workers.
Mold Growth in Municipal Building
A NJ municipal building was plagued by air quality complaints from city workers. Cracked ceiling plaster and several water leaks were noticed in a few areas. IR thermography determined that the cracked paint harbored hidden water damage and mold growth. Furthermore, IR inspections identified other areas where no cracking or water staining were observed from water leaks linked to major roof flashing problems. The pictures told a 1,000 words. The municipality was able to recover the cost of repairs from a roofer who had recently finished work there using substandard methods.
Infrared Thermal Imaging ("thermography") is an important technology in diagnosing the condition of buildings. Common uses of infrared inspection include:
- Water Leak Diagnosis and wet building material detection
- Mold Inspections
- Building Weatherization Inspections - missing insulation, air leaks, condensation problems
- Construction Defects - such as improperly installed radiant floor heating
Advantages of Infrared Building Inspection
Examples of Infrared Thermography uses:
Dark (purple and blue) colors shown in these examples are indicative of cool temperatures and water leaks.
Wet and moist building materials can destroy their structural integrity as well as create hidden mold growth. However, locating the exact source of leaks can be difficult to find without demolition. Infrared thermography offers a means to instantly show where materials are wet without having to demolish or disturb the structure. As a result, using IR frequently results in lower repair and reconstruction costs by targetting the precise problem area.
As the cost of energy and concerns about global warming increase, improving the energy efficiency of our homes and businesses becomes even more important. Thermal imaging provides a valuable tool to locate hidden building defects, such as missing insulation and air leaks, that rob buildings of conditioned air and ultimately $$$. All these conditions represent money being wasted to literally heat or cool the outdoors, not to mention discomfort to building occupants. These situations would be virtually undetectable without infrared thermography.
