A comparative study is performed to assess a hybrid building integrated photovoltaic/thermal (BIPV/T) system
and earth-air heat exchanger (EAHE) in comparison with individual BIPV/T and EAHE systems. Different systems
are examined based on energy, exergy, environmental, exergoeconomic, and enviroeconomic analysis. The
hybrid system is able to increase/decrease the outdoor air temperature in winter/summer and produce electricity.
A parametric study is also performed to inspect the impact of geometrical and operational metrics on the
exergoeconomic and enviroeconomic parameters of the hybrid system. The outcomes revealed that the hybrid
device produces higher annual total thermal and electrical energies by almost 10.1% and 935.6% compared with
the BIPV/T and EAHE systems, respectively. In addition, it was found that the hybrid system produces 3.2% less
annual total thermal and electrical exergy compared with the BIPV/T unit. While the hybrid system’s enviroeconomic
parameter was 3.2% less than the BIPV/T unit, its exergoeconomic parameter was 51% higher than
that for the BIPV/T system. The case study analysis indicated that the exergoeconomic parameter increases by
enhancing the air mass flow rate and EAHE length. Furthermore, it was found that the enviroeconomic parameter
increases for a higher length and width of the BIPV/T system.
