    The waste of energy in form of electricity to illuminate spaces inside the buildings is an important technical problem. Having the physical and creative solutions to introduce natural light inside buildings can reduce the electricity consumption. The technical solutions to illuminate and having control over the rays developed through out the history of architecture. Now, we have a whole range of different possibilities and it is important to emphasize that many of these solutions taking advantage of sunlight, have been commercialized and some of them developed and modified. However, only in the last decades researchers have been studying the potential of some design strategies and some specific products. To be aware of the advantages of using natural light as a source of energy and to give a general view of the lightning systems we need to know them. Engineers and physics have developed most of the natural illumination systems. The integration of these technologies to the designers and architects ́ knowledge can provide better energetic controls and solutions. The vertical transport natural light system “Lumiducts” within the illuminating solutions is a very interesting field with few years of studies and its use is still very limited. The “Lumiducts” are based in the principle of transporting light through the interior of a highly reflective surface. The advantage of this system is that it provides dynamic natural light in the interior of buildings and at the same time it saves electric energy using them as total or partial source of light. To evaluate the amount of natural light in the interior of a building we used a “Lumiduct” in a warm climate zone in days with different amount of sunlight.
