How does thermal imaging technology work?

Infrared cameras can help diagnose many home-performance issues, including air leaks and lack of insulation.

They have been used to analyze home-performance by energy auditors and contractors for decades. Without needing to open up your walls or ceilings for visual inspection, the images of these cameras can help locate missing or gaps in insulation, air leaks and moisture intrusion, among other things.

Infrared cameras do not measure surface temperatures, as many people assume. Instead, the camera measures the intensity of infrared radiation (meaning energy) being emitted by the surface it is aimed at.

Essess’ specific thermal imaging technology was developed by MIT researchers to address the problem of identifying energy loss and facilitating structural improvements to building envelopes in a scalable and cost-effective manner. Because each imaging rig can capture thermal images for thousands of homes in a single night, Essess offers a scalable and cost-effective way to gather intelligence around the building stock across an entire territory.

Essess manages a fleet of vehicles that have been repurposed with a custom designed thermal imaging rig. The vehicles also employ an on-board rig management system complete with a computer dashboard that contains a suite of driver and navigator tools to maintain and troubleshoot the imaging rig in real time, as well as optimize route planning.
