This new photovoltaic façade is comprised of amorphous silicon glass which is available in the market starting at $4.98/Sqft or 39€sqm, turning it into a highly competitive building material.Particularly, a combination between opaque photovoltaic glass together with 20% light transmittance glass has been chosen, enhancing the overall energy generation while allowing natural light into the building; this way, artificial lighting needs decrease while the inner comfort for the occupants is enhanced.Besides the electricity generation which is used to feed part of the building needs, the expenses in HVAC systems have decreased thanks to the thermal insulation that the photovoltaic glass offers, compared to a traditional ventilated façade.According to research carried out by Pais Vasco’s University together with the Building’s Quality Control Laboratories of that Regional Government, the thermal insulation that this photovoltaic glass entail allows the building to save up to 50% of its energy needs.For further details, please click here.
