Thermal Imaging Detects Energy Problems in Buildings

Essess has developed mobile thermal imaging technology and data analytics to identify and quantify energy losses across millions of buildings.

The company says it has raised $10.75 million since its founding in 2011 through investors including Vocap Investment Partners, DFJ Athena, Constellation Technology Ventures, Tamarisc and the Massachusetts Clean Energy Center.

The company recently completed field trials with its early deployment partners, including the US Department of Defense. These partners validated the company’s ability to deploy mobile thermal imaging that delivers actionable advice to motivate upgrades in building envelopes and HVAC systems. The company aims to scale its technology across millions buildings in partnership with electric and gas utilities, competitive energy suppliers, large energy service companies, and building materials and service providers.

Essess deploys vehicles with roof-mounted imaging systems that use multiple long wave and near infrared cameras, LIDAR devices, GPS units, and a range of other sensors. Combined with computer vision machine learning algorithms and heat flow analytics, Essess is able to identify automatically across large physical territories any abnormal heat signatures in buildings or other physical assets.

Earlier this year, the Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory said it was developing a portable system to generate indoor thermal maps. Using cameras and laser scanners mounted on a backpack, the portable Rapid Building Energy Modeler (RAPMOD) indoor mapping system creates a 3D visualization of walls, windows, floors, and other parts of buildings.
