Building’s energy consumption and specially for large buildings is an important component of the total energy consumption. Therefore, improving energy efficiency in buildings has become a global issue today in the fight against climate change. Accordingly, there have been numerous directives and bonuses promoted by the EU in recent years, which set the goal of decarbonisation by 2050. and to locate the status of energy consumption for these buildings different energy monitoring systems have been developed as a result of the fact that an excellent data-based energy management analysis can only be performed through energy monitoring “You can't manage what you can't measure”. Therefore, monitoring is the first and fundamental step in being able to optimize the building as it allows to understand the internal situation through the measurements recorded in the building by the sensors which send data that are not always optimal. In this regard, this thesis work focuses on analysis of the energy consumption, and in particular on thermal energy consumption (Heating and domestic hot water) of the energy center which is a building mainly used for offices use and located in the city of Turin (Piedmont region, Italy). The objective is to investigate the instrumental checks of a monitoring system for thermal energy that is consumed by the building. the state-of-the-art monitoring system allows to quantify the consumption spent by the machines for the production of energy vectors useful for providing the heating and DHW services essential to ensure comfort conditions inside the building by measuring the temperatures and flowrate through sensors and flow meters from siemens and Micronics with a consumption management software developed by an important company. The monitoring system provides the collected records of data that are measured with very high frequencies, approximately every 15 minutes, which is then has been rearranged to made it possible to develop a graphical analysis for the measured data of thermal energy consumption of heating and hot water supply inside the building that is met through the district heating system, solar thermal collectors, and geothermal polyvalent group during the heating season. The analysis revealed that the recorded data obtained from the readings of the thermal energy meter installed in the building relating to the recorded powers are reliable for energy consumption of hot water while are substantially dubious and of little reliability for energy consumption of district heating system due to zero consumption measured on the first two months of the heating season and fixed consumption measured at last three months from the heating season.
