As a result, it has been designed in two different sizes, based on the client's existing profile and aesthetic requirements: 426 units of 1,700x1,000 mm with transparency degree of 51 %, and 12 units of 1,000x850 mm with a transparency degree of 57 %."


Each PV glass is made of layers of heat-treated safety glass, which provides thermal and sound insulation. Besides, each unit has a bipolar rear junction box and a 4T+4T glass configuration, complying with all required certifications.

The Research and Transfer Laboratories Building (D4) is a specialized research and development center located on the Las Lagunillas campus. The building features modern and sustainable architecture and is equipped with cutting-edge technology to conduct advanced research in various areas such as energy, engineering, biotechnology, and computer science, among others. Additionally, the building houses 22 high-quality laboratories, including the Information and Communications Technology Research Laboratory and the Solar Energy Research Laboratory.


This project, designed by Caño Arbaiza architects, has had the close participation of ACCIONA alongside Vialterra in a temporary joint venture, acting both as main contractors.
