LINARES CITY HALL · JAEN, SPAIN
RENOVATION
This photovoltaic installation in Jaen involved replacing the conventional glass in the main building’s atrium with photovoltaic glass. This historic City Hall, constructed in the 19th Century, holds significant cultural importance in Jaen, and the renovation project aimed to preserve its original architecture. Onyx Solar was responsible for fabricating rectangular and triangular photovoltaic glass panel units using crystalline silicon solar cells, each tailored to fit the existing frame. The photovoltaic glass setup included an air spacer with a low-e coating and strategically placed clear areas to optimize natural daylight within the atrium. This sustainable upgrade not only enhances energy production but also respects the historical significance and architectural integrity of the City Hall in Linares. Moreover, the installation's visible light transmission (VLT) and solar heat gain coefficient (g-value) are excellently suited for Jaen's warm climate, ensuring a comfortable indoor environment while maximizing energy efficiency.
The characteristics of the photovoltaic glass used in the Linares City Hall project were specifically designed to exceed the client’s requirements. While the goal was to achieve at least 50% VLT and 50% solar factor, the project successfully surpassed these specifications, optimizing natural light intake and effectively managing solar heat gain. This balance is crucial for maintaining a pleasant atmosphere within the atrium, especially during the hot summer months typical of Jaen. By reaching a nominal power of 69 Wp per square meter, this photovoltaic glass not only contributes significantly to the building's energy needs but also aligns with the city’s sustainability objectives.
Additionally, the integration of photovoltaic glass enhances the aesthetic appeal of the atrium, creating a modern contrast with the historical architecture. This thoughtful design approach ensures that the installation is not only functional but also visually harmonious, showcasing how innovative technology can complement and enhance traditional structures. The successful implementation of this project demonstrates a commitment to sustainability while preserving cultural heritage, making the Linares City Hall a model for future renovations of historic buildings.
