Buildings are complex thermal systems. Energy management optimizations are challenging in protected heritage buildings. uvalgt measurement technology gives experts the data they need for such complex undertakings.
For this case study, greenteg was able to demonstrate the usefulness of uvalgt Building measurement methodology for supplying measurement data on a continuous basis: In this scenario, the measurement was year-round U-values for the windows in a listed building built in the 1930s.
When renovating a listed building in Switzerland, a minimum insulation standard (which varies from canton to canton) has to be achieved in order to receive grant funding. The aim was to determine the minimum insulation values needed for the renovation and ascertain the risk of dampness and mold in the basement.
The conditions imposed on listed buildings presented a particular challenge in terms of the insulation work. As the exterior of the building envelope could not be changed, internal wall insulation was required.
The U-value was measured in order to precisely assess the dimensions. This is often the only way to avoid losing too much valuable living space. The U-value measurements were combined with infrared thermal imaging measurements to verify their accuracy.
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.
