No, the BIPV photovoltaic glass structurally does not differ from other types of conventional glazing. Therefore, it is integrated into the building envelope (curtain wall, façade, or skylight) like any construction material. What solar control and comfort advantages does photovoltaic glass offer in a curtain wall?
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.
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.
They enhance thermal comfort and help prevent the greenhouse effect. A standard curtain wall offers no return on investment. In contrast, a photovoltaic curtain wall not only insulates the building but also generates power for over 30 years. This reduces monthly electricity bills and ultimately pays for itself over time.
