“…Considering cost and complexity to deploy a so large number of traditional sensors, and also to collect their data, we have chosen the distributed optical fiber thermometers, i.e. a Raman DTS-based solution, as in a previous project dealing with temperature sensing in underground GeoExchange System [8]. Such thermal monitoring is important, as functionalities and specifications of materials used to build the external envelope of a building, especially if it is labelled "low energy consumption", as they impact strongly energy leaks, inertia, permeability to external air, solar influence… i.e.…”

To reduce greenhouse gas emissions and to promote energy savings in the building sector, a project named Batimetre has been set-up, to measure parameters affecting building energy consumption. For the first time, optical fibers have been deployed on internal and external faces of two experimental houses, designed for low energy consumption. With a DTS Raman system, these cables provide a distributed measurement of walls temperature every meter and every two minutes. Such instrumentation is able to deliver a very large number of data at a reduced operating cost. It allows to isolate thermal phenomena in dynamic thermal simulation tools, and to compare several intermediate predicted and measured parameters.
