CAJASIETE BANK · TENERIFE, SPAIN
RENOVATION
This bank, leader in Canary Islands (Spain), underwent a sustainable transformation installing photovoltaic glass in its façade using the existing fixing system. The photovoltaic glass supplied was perforated to be installed using the existing spider system and became an evident feature recognizable by the public that serves as a visible testament to the bank’s commitment to sustainability. Comprising two layers of 8 mm laminated safety glass housing 6” solid solar cells, the layout was totally customized to allow a great amount of natural light to permeate inside the building and minimize the nominal power loss. At the same time the photovoltaic glass installed blocks the heat and harmful radiation to improve the comfort of the bank's employees. This installation involved irregular trapezoidal units creating a unique and visually appealing façade that enhances the bank’s environmental profile while revitalizing its external aesthetics.
In addition to the architectural innovation, the photovoltaic glass selected for the Cajasiete Bank project can reach a nominal power of 94 Wp per square meter, which significantly contributes to the building’s energy generation capacity. With a visible light transmission (VLT) and G-value both exceeding 50%, this glass strikes an optimal balance between generating renewable energy and allowing natural light into the workspace, creating a bright, open atmosphere for employees and customers alike. The higher VLT ensures the interior remains well-lit without sacrificing energy performance, while the G-value aids in reducing solar heat gain, keeping the building cool in Tenerife’s warm climate. This thoughtful combination of energy efficiency and occupant comfort aligns perfectly with the client’s needs, further reinforcing the bank’s commitment to sustainability while enhancing the building’s operational efficiency and environmental responsibility.
