Castellana 66
Context
The project is based on a clear vision: to transform an existing building into a benchmark for sustainability, energy efficiency and contemporary design. The architectural concept is based on the revaluation of the built environment through solutions that not only improve energy performance but also enhance the spatial and aesthetic quality of the property.
The intervention was conceived as an opportunity to rethink the building’s envelope, giving it a new visual and functional identity. Priority was given to the harmonious integration of technology, comfort and design, with a focus on the user and positive environmental impact.
Scope
At Aluman, we have developed a new envelope for this iconic office building, located in the heart of Madrid’s financial district, with the aim of combining efficiency, aesthetics and sustainability.
The proposal incorporates an innovative and multifunctional façade, composed of:
- Glazed areas with openings, which promote natural lighting and ventilation.
- Opaque sandwich panels, which improve thermal and acoustic insulation.
- Dekton® ceramic tiles by Cosentino, which provide durability, resistance and a contemporary image.
One of the most striking elements of the design is the integration of solar glass modules in vertical and horizontal slats, which act as thermal visors and, at the same time, generate photovoltaic energy, contributing to the building’s energy self-sufficiency.
In addition, triangular honeycomb geometries protruding from the façade were incorporated, giving it a dynamic, elegant and distinctive character and reinforcing the visual identity of the building.
Challenge
The main challenge of the project was to carry out a comprehensive energy renovation under a strict schedule of deadlines and protocols, ensuring minimal impact on the daily activities of the tenants at all times. Added to this was the need to comply with current environmental requirements aimed at reducing energy consumption and greenhouse gas emissions.
At Aluman, we overcame these challenges through meticulous planning, precise execution and the implementation of innovative and sustainable solutions, which significantly improved the building’s energy efficiency without compromising its functionality or aesthetics.
