In the heart of Santiago de Compostela, Spain, the Espellos building, part of the San Caetano administrative complex, underwent a significant transformation in 2023. Led by Díaz y Díaz Arquitectos in collaboration with MIBA Architects, the renovation project focused on enhancing energy efficiency and modernizing the building’s appearance while preserving its historical context.
Architectural Features
Originally constructed in 1985, the Espellos building stands out with its unique configuration, featuring both trapezoidal and rectangular floor plans across different levels. To revitalize its energy performance and aesthetic appeal, the renovation project targeted the building’s envelope, aiming to seamlessly integrate it with the existing complex.
Envelope Renovation
The renovation efforts centered on creating a contemporary facade that harmonizes with the surrounding structures. A continuous base was established to provide a unified appearance, while new materials were carefully selected to complement the historical elements of the complex. The facade features high-energy performance materials, including pitched tile roofs, white mortar facades, wooden joinery with granite surrounds, and granite baseboards, blending tradition with modernity.
Functional Enhancements
Beyond aesthetic improvements, the renovation aimed to enhance working conditions for administrative staff and improve service quality for the public. The installation of a new air conditioning system and the integration of renewable energy sources such as biomass and photovoltaic solar panels were key strategies employed to optimize the building’s energy efficiency and reduce its environmental impact.
Conclusion
The renovation of the Espellos building envelope represents a successful marriage of sustainability, functionality, and architectural integrity. By preserving historical elements while embracing modern design principles and energy-efficient technologies, Díaz y Díaz Arquitectos and MIBA Architects have revitalized the building, ensuring its relevance and functionality for years to come in the bustling administrative hub of Santiago de Compostela.
