Modelling conditions & methodology
This study used TRNSYS 17, unsteady analysis software, for a simulation analysis of DSF and PV
DSF. Thermal properties and building energy were compared under the same conditions.
The DSF and PV DSF building models were simulated using a Type 56 building component and a
Type 567 BIPV component, and climate data for Daejeon, South Korea was used.
In TRNSYS, the key BIPV parameters and input values were as listed in Table 2. The PV installation
area was 10.08m2, and 15% (1.5kWp) efficiency was assumed. The indoor cooling/heating temperature was set as 22°C and 26°C for winter and summer, respectively. The cavity space zone, subject
to natural convection conditions, had an air flow of 78 CMH (Ji Hye Lim 2010), and the number of
ventilations was 5/h in the cavity space zone.
