The present paper reports the results of a 30-month-long monitoring campaign of a EAHX (earth-to-air heat exchanger) system installed in a school building in Imola (ITA). The horizontal EAHX is divided into three fields for a total of 32 buried pipes. The system pre-treats the inlet air of three dedicated AHUs. The analysis follows a consolidate methodology used in a previous shorter monitoring of the first Imola's field that was already published. In this study, a comparison between different years of monitoring is introduced, together with the soil temperature trends of the first field.
