SEA TOWERS · BARCELONA, SPAIN
NEW CONSTRUCTION
The Sea Towers complex in the 22@ district of Barcelona stands as the third building in Spain to achieve the esteemed LEED Platinum certification. This recognition stems from its sustainable and innovative design, leveraging green technologies like photovoltaic glass. These towers boast remarkable energy efficiency, achieving a 52% energy saving. Onyx Solar’s solar photovoltaic glass adorns the curtain wall of the Sea Towers, comprising 1,520 m2 of amorphous silicon photovoltaic glass customized in various dimensions. Each insulating glass unit incorporates a 12 mm air chamber, enhancing the building’s thermal and acoustic insulation. In addition the photovoltaic glass manufactured allows the entrance of a good amount of natural light and filter harmful radiation to maximize the comfort inside the building. Situated in the heart of Barcelona’s 22@ district, a prominent technological and digital hub, the Sea Towers underscore the city’s position as a significant global tech destination.
The characteristics of the photovoltaic glass used in the Sea Towers were precisely tailored to meet the project’s goals for sustainability, energy efficiency, and occupant comfort. Its nominal power can reach 34 Wp per square meter, the photovoltaic glass contributes substantially to the energy-saving strategies of the building while maintaining a modern, sleek design. Its visible light transmission of 20% allows for the perfect balance between natural light intake and glare control, creating a bright and comfortable interior without compromising on energy efficiency. The G-value of 32% ensures effective management of solar heat gain, reducing the cooling demand during Barcelona’s hot summers. The combination of high-performance insulation, energy generation, and natural light control makes the photovoltaic glass a vital component in the building’s ability to achieve such significant energy savings and meet the stringent requirements for LEED Platinum certification.
