Technical FAQs 3

Where is solar XXI building located?

Office building for the Energy Efficiency Unit, LNEG campus, Lisbon SOLAR XXI building is located inside the LNEG campus - National Laboratory of Energy and Geology - in Lisbon. Built in 2006 as part of a research project, its main objective is to be an example of a low energy office building using a combination

What is a photovoltaic curtain wall?

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.

Does Photovoltaic Glass fit in a curtain wall?

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?
