Energy Building Sustainability by Optimized Daylight Tubes

Resumen

New interest in Innovative Daylight Systems has emerged strongly because energy consumption must be reduced, and human environment conditions improved. Light propagated through prismatic films, exhibits a characteristic behavior optimal for energy savings, sustainability and environmental conservation. These optical particularities and capabilities can be useful for multiple applications in areas such as architectural lighting, automotive lighting, and display technology. Therefore, it is essential to consider the optical properties of these singular light guiding systems to control light energy and thus, accurate simulations and modeling are necessary to improve the designs. In this study, the application of Fresnel's equations is compared with basic Snell's law showing the angular propagation differences and the influence of defects in peak’s prism is quantified. In this framework, a prototype in real scale has been developed and tested.
