Electrical and optical properties of semitransparent BIPV: case studies from different locations.

Location	Description	Results	Reference
Brazil	The energy-saving potential of semitransparent PV windows was investigated.	30% of the total HVAC was saved using daylight.; 18%-59% of NEB was achieved.	[29, 91]
Brazil	Semitransparent photovoltaic panels in windows were evaluated.	The reduction in the final energy consumption ranged from 19% to 43%.	[90]
Canada	Potential benefits of semitransparent photovoltaic windows were evaluated by simulation.	The STPV module with 10% visible effective transmittance resulted in the lower electricity consumption of 5 kWh/m^2/yr.	[89]
India	The three semitransparent BIPV on power and optical properties were evaluated.	The values of VLT for the three PV modules were in the 7.09%–23.49% range, and power generation and efficiency increased by around 0.01–0.13%.	[92]
Italy	A comparison of BIPV facade semitransparent modules for the human comfort conditions was conducted.	A room with semitransparent PV performs better than that with a-Si PV module.	[93]
Spain	Impacts of optical characteristics on the energy performance of semitransparent PV windows were investigated.	Net energy savings of 3.0–8.7% were achieved.	[78]
Spain	Energy performance of the WWR of five STPV elements was evaluated.	Energy saving potential ranges between 18% and 59% compared to the normal glass.	[91]
Singapore	Performance of semitransparent BIPV windows in a tropical climate was conducted.	The NEBs vary from 1.79 to 23.26 kWh/m^2/yr and increase steadily with the increase in WWR.	[72]
