Abstract

The complexity of lighting studies necessitates the evaluation of lighting levels and spatial quality to ensure user comfort. Architects demonstrate a commitment to designing environments that prioritize internal visual performance, integration with the external surroundings and energy efficiency.

However, there is a neglect of the urban context in relation to internal performance expectations. Buildings are conceived using glazed or reflective and emissive surfaces that redirect visible and thermal incident radiation back to the city, thereby reducing internal heat gains.

Daylight radiation at high intensity causes glare phenomena, which refers to visual discomfort experienced by pedestrians and has an impact on the local microclimate by increasing the surrounding temperature.

It is understood that the urban environmental quality can be ensured through an assessment and classification procedure that considers the probability of glare occurrence during the project design, specifically focusing on façade performance.

The rating scale will be built based from the results of parametric ray-tracing simulations involving different geometric shapes and façade surfaces, resulting in heat maps.

The final evaluation will be by mean of a combined classification approach, taking into account the probability of glare occurrence as determined by the geometric shape and surface materiality of the building envelope.
