Enhancing the neutral: white surfaces and luminous quality in the historic spaces of Villa Argentina

The USI Academy of Architecture in Mendrisio is housed in Villa Argentina, which offers a unique setting for investigating how natural light and white surfaces affect how historical spaces are perceived and enhanced. This article analyzes, through photographic documentation and illuminance measurements, aims to analyze how the predominance of white on the interior walls, combined with the villa's particular architectural configuration, influences the luminous quality, chromatic perception, and user experience. Despite their neutrality, the white walls transform into dynamic surfaces, allowing natural light to be reflected and diffused, increasing brightness and promoting an even distribution of light. This creates a sense of openness, lightness, and spatial continuity, making rooms more welcoming for office activities. The combination of white and natural light promotes user well-being, concentration, and a serene environment. The study emphasizes the importance of combining chromatic analysis and lighting technology to preserve and improve historic structures.
