Spatial architecture plays a crucial role in the success of treatment, underscoring the necessity for designers to meticulously assess all aspects of hospital design. This thesis concentrates on lighting, investigating how different architectural elements, particularly those integrating natural light, affect the circadian rhythm of both staff and patients.

Focusing on the case study of Western University Hospital—an exemplar of purely-functional and non-transparent architectural office buildings—this research entails a comprehensive evaluation of the quantity and quality of light distribution within the building. The hospital is clearly restrained by the uniform lighting design, lacking differentiated analysis of location or frequency of various visual tasks.

Building upon these findings, the thesis proposes an interior and exterior renovation of the hospital in accordance with modern standards of care in architecture. The new design prioritizes the quality of natural light, appreciating its ever-changing beauty through increased transparency of the building and reductive/additive curving of its volume.
