Smart U-Value Measurement

Smart U-Value Measurement

Smart, Wireless and Scalable Building Measurement System

A large part of the energy consumption is caused by badly insulated buildings. The latest Measurement Solution offered by Partel enables you to precisely assess U-values, R-values, and multiple points across your building. On the basis of the measured data, energetic retrofitting can be planned accordingly.

Our portable measurement approach uses heat flux meters (HFM) and temperature sensors for quick and accurate measurements over several days to months with the possibility of real-time monitoring. This approach is standardized in ISO 9869, ASTM 31046 and ASTM C1155. This is the only method that delivers accurate quantitative in-situ information about a building envelope performance.
