Uvalgt wireless kit in use by the city of basel

U-value measurement saves on renovation costs. Measuring devices that locate thermal weak points are also making an important contribution to climate protection. And that’s precisely why they’re being used by energy consultants.


Just a few years ago, invasive measures such as drilling were still required for U-value measurements. These measures are not only cumbersome, but also imprecise as conductivity varies greatly depending on the material composition.

U-value measurement allows for optimized structural measures during renovation projects. It can also be used to assess windows. If double glazing with a good U-value is installed in intact window frames, there’s often no need to replace a window. In this case, other measures deliver the greatest effect.

The energy consultants for the city of Basel are using uvalgt Building measuring technology – in combination with other standard measurement methods – for thermal evaluation of buildings and structural elements.


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.
