Análise de projetos de iluminação de ambientes hospitalares considerando o ciclo circadiano humano

Abstract

The present study analyzes the natural and artificial lighting conditions of hospital inpatient rooms, aiming to demonstrate how the application of integrative lighting can contribute to visual comfort, well-being, and the regulation of patients’ circadian rhythms. Accordingly, the central objective is to investigate design and technological solutions for integrative lighting based on the premises of the Morphological Diagram—an analytical tool dedicated to optimizing the use of natural light—and the Lucas Spreadsheet, applied to assessing the performance of lamps and artificial lighting in relation to user health. The research was conducted using the Design Science Research methodological approach, integrating bibliographic and documentary review to understand architectural design principles as well as the technical and biological foundations that link lighting, circadian rhythms, and human well-being. In the second stage, two inpatient rooms from different hospitals were analyzed to evaluate their current conditions in terms of the impacts of natural and artificial light, in accordance with the previously discussed concepts. The findings show that the methodological combination of the Morphological Diagram and the Lucas Spreadsheet constitutes an effective strategy for the integrated evaluation of light in inpatient settings, providing support for architects and designers to optimize lighting conditions, promote the preservation of biological rhythms, and improve environmental comfort in hospital spaces.
