Sunlight as a Fundamental Resource in Bioclimatic and Sustainable Architectural Design

Objective: To describe how bioclimatic architecture and sustainable design intelligently integrate sunlight to promote more energy-efficient buildings and create living spaces that promote human well-being and harmony with the natural environment.Methodology: A comprehensive narrative review was conducted by consulting databases such as Archidaily, Google Scholar, Scielo and Journal of Architectural Lighting, using key terms related to the sun and bioclimatic architecture, in publications from 2019 to 2024, and selecting 23 relevant articles after a rigorous filtering process.Results: The historical and contemporary importance of the sun in architectural design is evidenced, evidencing how diverse cultures have implemented strategies to harness sunlight and photovoltaics. Examples of integration of solar technologies, passive techniques for thermal control, and the inspiring influence of the sun on visionary architects such as Le Corbusier were highlighted.Conclusion: The sun is not only a practical source for solving energy and environmental challenges, but also an opportunity to design healthier, more sustainable and aesthetically enriching environments. The need for further research on new methodologies and strategies to enhance the efficient use of solar energy in future architecture is pointed out.
