OMBÚ ACCIONA · MADRID, SPAIN
RENOVATION
Originally erected in 1905 by architect Luis de Landecho this historic building was totally refurbished in 2022 by two titans: Norman Foster (Laureate of the Pritzker Prize) and Acciona (gobal leader in renewables and infraestructures). Onyx Solar's was key in achieving Platinum LEED certification. We manufactured see-through photovoltaic insulating glass panels of 4 x 2 meters. These units, configured with 6+3+6 mm glass and a 16 mm argon chamber, provide enhanced thermal and acoustic insulation. At the same time they allow the entrance of natural light, block the heat and produce free and clean energy thanks to the sun.
The photovoltaic glass used in the Ombú Acciona project was specifically designed to meet the unique needs of the building, balancing energy efficiency and comfort while preserving the architectural integrity of the historic structure. With a nominal power that can reach 40 Wp per square meter, the photovoltaic glass ensures a consistent source of renewable energy, aligning with Acciona’s sustainability goals. The 10% visible light transmission allows natural light to permeate the interior, enhancing the workspace ambiance without compromising privacy or thermal comfort. Additionally, the 30% g-value ensures effective control of solar heat gain, reducing the building’s reliance on air conditioning and contributing to lower energy consumption. This integration of photovoltaic glass not only modernizes the building's energy profile but also supports its role as a symbol of forward-thinking architecture, blending historical preservation with cutting-edge technology for a greener future.
