The progressive climate change caused by anthropological factors has led EU member states to set themselves a very ambitious goal of achieving climate neutrality by 2050. Within the packages and regulations, a CO emissions system (EU ETS) has already been in place since 2005, affecting energy-intensive industries, energy producers and airlines. It is planned that from 2027 the ETS2 system will apply, which will cover CO emissions from burning fuels in buildings and road transport. The ETS2 means that gas, coal and fuel oil, i.e. fossil fuels used to heat households, will be subject to taxation. The most effective way to reduce the consumption of these fuels is to reduce the energy intensity of buildings. This can be achieved using appropriate thermal insulation of building envelopes/partitions. Knowledge of the temperature distribution inside a partition can significantly improve the process of thermo-modernization in existing buildings. The paper presents the method and results of the measurement of the thermal distribution inside a reinforced-concrete building wall using FBG sensors.
