ESSEN´S OLD CUSTOMS · ESSEN, BELGIUM
RENOVATION
This building, which dates back to the early 1900s, originally functioned as a transhipment warehouse and served as a border station between Belgium and the Netherlands. Now fully retrofitted, it stands as a center for sustainability. Onyx Solar was crucial in the manufacturing of photovoltaic glass that was installed to rejuvenate the existing skylight. The 750 m² (8,070 SqFt) skylight integrates 440 units of amorphous silicon photovoltaic glass boasting a great capability to allow the entrance of natural light. The photovoltaic glass units manufactured incorporate 15mm argon chamber to provide the insulation required by customer. On top of this these insulated glass units (IGU) will generate 600 MWh of clean energy and avert the emission of 400 tons of CO2 into the atmosphere throughout their lifespan. The glass was custom-made to achieve the desired balance between nominal power, VLT and SHGC (g-value)
The photovoltaic glass chosen for the Essen Old Customs building was specifically designed to meet the unique challenges of retrofitting a historical structure while adhering to modern sustainability standards. Its incorporation not only respects the architectural integrity of the original building but also improves its energy performance significantly. With its excellent thermal insulation properties, the glass reduces energy loss during colder months, making it suitable for the Belgian climate. The custom SHGC (g-value) ensures the skylight effectively manages solar heat gain, keeping the building comfortable in both summer and winter. Additionally, the natural light allowed through the skylight minimizes the need for artificial lighting, reducing the overall energy demand of the facility. This photovoltaic glass solution balances historical preservation with cutting-edge energy technology, aligning with the client's goals of sustainability, efficiency, and aesthetic enhancement.
