What role does natural light play in Brutalist Modernism architecture?

In Brutalist Modernism architecture, natural light often plays a significant role in shaping the design and overall aesthetic of the buildings. Here are a few key aspects of natural light's role in this architectural style:

1. Expression of Structure: One of the central principles of Brutalist architecture is to express the structural elements and materials clearly. Natural light is used to accentuate the raw forms, textures, and patterns of concrete or other materials typically used in this style. The interplay between light and shadow highlights the rugged nature of the structure and creates a sense of visual drama.

2. Highlighting Materiality: Natural light can emphasize the materiality and surface qualities of the building materials, particularly concrete. Daylight, flooding in through the openings or filtered through a brise-soleil (a sunshade or screen), can cast fascinating shadows, revealing the rough texture, imperfections, and tonal variations of the concrete surfaces, which is characteristic of Brutalist architecture.

3. Spatial Experience: The use of natural light can greatly enhance the spatial experience within Brutalist buildings. Designers often carefully consider how daylight enters the spaces, casting patterns or creating specific atmospheres. Strategic placement of windows, skylights, or lightwells allows for controlled daylight penetration, creating contrasting zones of brightness and shadow while illuminating particular areas of interest.

4. Connection with Nature: Brutalist Modernism architecture often seeks a connection between the built environment and the natural surroundings. Incorporating ample glazing, courtyards, or large openings allows for unobstructed views of the external landscape, bringing the outside in and promoting a sense of harmony with nature.

5. Emotional Impact: Natural light can evoke different emotions and moods in architectural spaces. Within Brutalist Modernism, the juxtaposition of harsh, solid structures with softer, diffused natural light can create a rich sensory experience. The play of light and shadow can instill a sense of awe, tranquility, or contemplation, enhancing the monumentality and character of the architecture.

It's important to note that the design approach can vary among different architects and projects within the Brutalist Modernism movement. Nevertheless, natural light is often thoughtfully considered to enhance the intended expression, form, and experience of the architecture.
