Natural light received by the retina aids in synchronizing the human circadian cycle, influencing alertness and productivity throughout the day. This influence can be estimated through computational simulation or measurement. The objective was to perform a comparative evaluation of the equivalent melanopic ratio values measured in a real environment, in a scale model, and simulated computationally. The method involves in situ measurements of melanopic illuminance from a reduced-scale model, simultaneously conducted in the real environment, followed by subsequent simulations in a digital model using the ALFA program. Although the magnitudes vary, the trend lines of the program's results show similar behavior. It is important to note that the program has limitations regarding the type of sky, distinguishing between static and real sky conditions. Despite this, ALFA proves to be a useful project guidance tool, as it enables architects to understand how a building will behave under natural light conditions and what stimuli the environment can provide according to circadian cycle metrics.
