Kinetic Super-Resolution Long-Wave Infrared Thermography Diagnostic for Building Envelopes
The objective of this project is to demonstrate and validate rapid kinetic super resolution (KSR) long-wave infrared imaging and analysis as a diagnostic tool to enhance the capabilities of conventional thermographic imaging for assessing building energy loss. The KSR technology allows thermal imaging of multiple buildings in a way that is not currently possible with conventional thermography. Rapid assessment of the energy loss from hundreds of building envelopes is possible from scans taken in just a few hours, via drive-by along the street where the buildings are located.
KSR thermography can help detect problems invisible to the naked eye, including missing, damaged, or improperly installed insulation within walls and roofs; thermal bridges; and poor seals. For example, most thermal bridges have a distinctive spatial signature, which yields a thermal image with relatively uniform hot areas surrounded by relatively uniform cooler areas, separated by a steep temperature gradient. KSR imaging enables an assessor to quickly identify energy loss problems in the envelope, estimate the extent of the problems, develop preliminary plans for remediation, and confirm that the problem has in fact been addressed.
KSR long-wave infrared thermography is expected to be a useful tool for decision making associated with energy upgrades and management, as it can rapidly identify and quantify energy losses in hundreds of buildings within just a few hours. This technology can be used in many locations to evaluate the energy intensity of thermal bridges and energy leaks so that better energy-upgrade decisions can be made. In particular, KSR can be used in combination with conventional thermography to provide a more rapid assessment of the building envelope energy efficiency to an extent not possible with conventional thermographic imaging alone.
