Every day, men and women living in environments in which the predominant lighting is artificial sources. To counteract this, is possible to use daylighting systems for entry natural light to interior spaces. However, there is still great difficulty to find light performance data of these systems, creating uncertainty among architects and designers when planning the lighting of spaces using these devices. This work proposes to validate the use of the TIP-HDRI technique to evaluate and predict the performance of tubular daylighting systems. As a result, it shows a comparative analysis between the luminous flux measured using an array of illuminance sensors, and measured TIP-HDRI technique. A concrete example of application is shown by measuring of the luminous flux emitted month by month, for three self-manufacturing lightpipes, installed in actual use, in a residential environment, of cities with sunny climates, for a period of one year.
