About

HEAT3D Pro

Features
Read full description

Heat3D 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 an hour 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 or gain through these surfaces and calculate the U-value. Measuring an accurate 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. There is short video demonstrating how to use HEAT3D to capture a 3D energy survey of a room in 1 minute on the HEAT3D website - https://heat3d.net Why measure U-values using Heat3D? -Improved EPC accuracy Use the measured U value in EPC reports as opposed to calculated ones that can be +/-50% or more out. -Determine insulation levels Understand baseline thermal transmittance of walls and current insulation levels, allowing better target investment in insulation upgrades. -Retrofit improvement Measure before and after insulation upgrades or retrofit works to determine the true energy, running cost and CO₂ savings delivered by improvements. -Check quality assurance Check that the actual performance meets the designed performance. Identify poor installations, workmanship and conduct quality assurance testing. -Reduced remedial work Measure during works and before completion to check that desired outcomes are being achieved. Save time, costs and improve quality by identifying issues and reducing remedial action. Who is Heat3D designed for? Heat3D can be used by anyone who wants to know the U-value or thermal performance of building elements in-situ. Measurements can be taken before, during and after insulation upgrades to verify performance improvements; Architects, Building Managers, Building Surveyors, Energy Assessors, House Builders, Insulation Installers, Retrofit Coordinators, Sustainability Consultants A GPS enabled iPhone or iPad device with ARKit is required ( Wifi only iPad is not supported). You’ll need a FLIROne® camera. We recommend using the FLIR One Pro if possible, it will produce more accurate measurements and with higher resolution. An enviromental and a radiative temperature target is required to achieve ISO 9869 part 2 accuracy with HEAT3D Pro. Please contact business@electricpocket.com for advice on obtaining these. ARKit Compatible devices iPhone 8 and later iPhone X and later iPad (2019) and later Heat3D is the product of years of research and real-world testing into quantitative infrared thermography techniques. It has been successfully tested and proven in the lab and over 24 buildings of varying construction and age and shown to provide the same level of accuracy for heat flow and U value measurements as the very expensive and time consuming ISO 9869 standards approved HeatFlux plate method.
