Summary

Supplement 9 to the ITU-T L series of Recommendations refers to the best practices defined in Recommendation ITU-T L.1300. More precisely, this Supplement provides details of a case study related to the reduction of the energy spent for air conditioning through the use of optical fibre based thermometry. A general description of the temperature measurement is provided, then the optimization process for the air conditioning is highlighted. Finally, the results of temperature measurements made using optical fibre sensors are shown.
