A multi-dimensional evaluation of the semi-transparent photovoltaic glass curtain wall and the LOW-E glass curtain wall is conducted. The study analyzes the advantages of using photovoltaic curtain walls in high-rise buildings regarding energy consumption, lighting comfort, cost, and energy efficiency.
Cost-wise, photovoltaic curtain wall glass costs 477.177/m 2, lower than the 549.815/m 2 for solar control glass with the same effect. The study suggests using Low-e glass for floors 1–20 and photovoltaic glass above to reduce LCOE to 0.894/kWh.

Using photovoltaic glass as curtain walls involves a simplified method, treating each room facade as a continuous glass panel for description and calculation. Low-e and Clear glass are selected from the NFRC - compiled IGDB (International Glazing Database).
For instance, in areas with abundant solar radiation, low-AVT and high-PCE photovoltaic curtain walls (like those with AVT of 0.4 and PCE of 12 %) can greatly cut cooling energy use while slightly raising heating and lighting energy consumption. Moreover, they boost electricity generation without significantly increasing manufacturing costs.
