Background

A variety of measurements must be taken to precisely calculate a building’s U-value: the surface temperature of the interior and exterior walls, the ambient air temperature and the heat flux, measured on the interior facade.

With the uvalgt Building measurement process, the surface and outdoor temperatures are measured on the outer shell by means of temperature sensors. One heat flux sensor and two temperature sensors are applied to the interior wall to measure the surface and ambient air temperatures. A data logger stores all of the information and calculates the U-value using the software supplied.

This compact all-in-one measuring system is the perfect solution for determining a building’s most important energy values, and provides insights into energy consumption, energy efficiency and the quality of the building envelope.

Solution

uvalgt Building sensor technology allows for straightforward and precise measurement of the U-value of building envelopes, structural elements, and materials.

The uvalgt wireless kit data measuring device is used to conduct simultaneous measurements of the U-value and the ambient and surface temperatures (indoors and outdoors) at five sensor points, with the option of cloud-based data transmission, analysis and monitoring in real time.
