Heat3D is an innovative mobile app that allows you to precisely measure heat flow and U-values of building elements using a low-cost, quick and non-invasive method.
Heat3D is designed to work on iPhones and iPads and uses a portable thermal camera to obtain results in a matter of hours as opposed to days or weeks using heat flux plates. The rapid nature of the measurement enables quantified U-values that are more accurate than manual calculation methods but achievable in a similar amount of time.
The Heat3D iOS app uses Apple ARKit to detect room features such as walls, floors and ceilings and construct a 3D model. When combined with a FLIR portable camera, infrared thermal images are projected onto the 3D model showing the heat signature through each surface. Quantitative infrared thermography is used to calculate the heat loss through these surfaces and, using temperature sensors, a U-value is calculated and presented on the device.
Measuring a U value across an entire element with Heat3D can take as little as 1-hour meaning that the measurement of actual U-values is now possible in all projects.
