TWIN CITY CENTER · BRATISLAVA, SLOVAKIA
NEW CONSTRUCTION
The Twin City Tower, developed by HB Reavis, stands as an iconic addition to Bratislava’s business landscape, offering premium office and retail spaces within a newly established business center. Its striking façade integrates Onyx Solar’s amorphous silicon photovoltaic glass. Notably, this photovoltaic glass not only contributes to the building’s energy generation but also optimizes thermal insulation with its argon spacer and low-e coating. Architecturally seamless and fully opaque, it blends seamlessly with the overall design of the façade, a testament to its integration within the building. Skanska, the construction company behind the building, boasts a rich legacy since its establishment in 1887. It operates extensively across the Nordic markets, Europe, and North America.
The photovoltaic glass installed in the Twin City Tower can reach a nominal power of 57 Wp per square meter, a highly efficient solution tailored to meet the building’s energy needs. With a 0% visible light transmission, the glass is completely opaque, ensuring optimal privacy for the interior spaces while enhancing the building’s sleek, modern aesthetic. Its g-value of 6% effectively controls solar heat gain, ensuring that the internal climate remains comfortable year-round, even during Slovakia’s hot summers. This balance between energy generation, heat control, and aesthetic design aligns perfectly with the client’s specifications, providing a sustainable, future-ready solution. The use of this high-performance photovoltaic glass not only reduces the building’s carbon footprint but also elevates its energy efficiency, positioning Twin City Tower as a leader in eco-friendly architectural innovation in Bratislava’s fast-growing urban landscape.
