Resumen:
Nowadays, many working environments are located within facilities that are not visually connected with the exterior.
This is due to the new architectural paradigms as regards design, based on the possibility to substitute natural light
for artificial lighting even in daytime. Accordingly, the need of reducing energy costs and the user s wish to optimize
lighting and visual comfort levels raises the option of innovative natural lighting systems implementation. For a
luminous retrofitting case, located in Mendoza, Argentina, a specific methodology used determined that the more
adequate natural lighting strategy would be redirecting direct sunlight, working on the reflected light design. The
methodology proposed is formed by an analysis of the initial situation, conditions modelization, and design resolving
proposals, through luminous evaluation, real and virtual scale model construction, and performance evaluation using
heliodon and simulation software. This work points to refunctionalize natural lighting and to increase the application
of innovative natural lighting systems design. In the mentioned case, strategies of redirection of the solar component
capable of optimizing indoor lighting levels up to a 40% were applied.
