Resumen
This article investigates the operation of a Mechanical Heat Recovery Ventilation(MHRV) system in an overheating nZEB apartment in Spain. The building, an apartment tower,was found to have a moderate to severe issue of overheating during extensive parts of the year.The study focuses on a flat located on the top floor of the Bolueta tower I in Bilbao, Spain, whichis the world's tallest Passivhaus building. Temperature and relative humidity data loggers wereplaced in various locations inside and outside the flat, as well as an amperemeter to monitor theoperating regime of the MHRV unit's fans. The study covered a period of 18 months andconsisted in an exploratory analysis of the data obtained. The results show that the dwelling andits ventilation system partially correspond to the expected performance during the cold seasonbut deviate from the usual design assumptions considered for the warm periods. The MHRV unitmay have difficulties entering bypass mode and providing sufficient free cooling to maintainadequate indoor temperatures due to its placement. These findings provide insight into thethermal performance of the building and operation of the MHRV system and can inform futureresearch
