Given the right conditions most buildings exhibit characteristic thermal patterns that can be interpreted by a qualified person. Rather, the temperature differences are normally of most interest. Although it may sometimes be useful to display temperature values, this is often not required in building work. Different radiant temperatures are shown as different colors or shades of gray. The image is displayed live in a viewfinder or on an LCD view screen. These portable, battery-operated instruments record the thermal data either as still, digital images or on conventional videotape or digital video. They convert this radiation into thermal images, or thermograms, which visually portray temperature differences as small as 0.05☌. Infrared cameras are specially-designed electronic devices that detect thermal radiation. You've felt this energy emitted by the sun or a stove burner. When people act on this information, significant savings result and buildings are more comfortable! All surfaces radiate invisible heat energy. When properly used, thermography enables building owners, architects, contractors and inspectors to locate problems, verify building performance, and validate solutions. When properly used, thermal imaging enables building owners, architects, contractors and inspectors to verify building performance, identify potential problem areas and validate corrective solutions.Ī great value of infrared thermography is that it provides a means of seeing the invisible thermal signatures related to many of these problems in building. Despite this unfortunate resolution, the thermograms helped the owners negotiate a financial settlement with the architects and contractors. In the end the owners simply lived with the continued problem because corrective actions were deemed too expensive. Hundreds of thousands of dollars were spent in various, poorly planned attempts to correct the underlying causes. For example, a commercial building, a nursing home, had extensive problems resulting from a poorly designed roof/ceiling insulation system these included excessive heat loss during the winter months and, as a result, extensive ice damage due to snow melt. At that point the only recourse may be extensive, costly reconstruction. Often the problems - as well as their causes and consequences - simply cannot be seen until after costly damage has been done. "Sick building syndrome," mold growth and other health related issues.Inadequate verification of construction details or structural performance delaminations of façade materials.Moisture damage due to leaks or condensation, especially in the walls or roofs.Excessive energy use due to missing or damaged insulation, insulation that is performing inadequately, and excessive air-leakage across the thermal perimeter.The major problems found in buildings include: ![]() Buildings of all sorts, from homes to factories to high rises, can be troubled by problems related to design, construction and maintenance that can be difficult to diagnose and resolve.
