METODOLOGIA PARA ANÁLISE DE ILUMINAÇÃO NATURAL ZENITAL EM QUADRAS POLIESPORTIVAS

Abstract

Architectural design is the main contributing factor to predict daylighting quantity and quality control of buildings. When well conducted, can provide appropriate lighting, balanced spectrum and distribution colors, energy savings and biological, physiological and psychological benefits to users. Increase its use is desirable, but it must be carefully done. In sports facilities, due to the large surfaces, the design takes special cares to maintain homogeneous levels of illuminance throughout the space, avoiding excessive glare, high contrasts, reflections or momentary vision loss to users. In addition, there is also a large variability of visual activities and directions, as well as sports type in the same facility. The objective of this research was verify a methodology to evaluate daylight in sport halls based on daylight availability and the daylight glare probability in users. The application was performed in three toplighting systems: skylights, saw tooth and monitors and analyzes was performed with computer simulation in three evaluation phases: dynamic measurements of sUDI [300-2000lux, 50% h] (Spatial Useful Daylight Illuminances), ASE [1.000lux, 250h] (Annual Sunlight Exposure) and DGP index (Daylight Glare Probability) with Annual Glare tool. Towards this end, the results show that the methodology was appropriate to base the evaluation method and the computational simulation was essential for the accomplishment dynamic analyzes of daylight environments throughout from every hour of the day to every day of the year; which would be impracticable through site mappings in real spaces of sports halls, that allow only static and point analysis.
