Abstract
This work has the objective of developing a methodology for the evaluation of indoor natural lighting systems, which, with speed and practicality, provides from real conditions of use a reliable result about the quality and performance of the proposed system. The methodology is based on the construction of two real-size test environments, which will be subjected to a natural light system through reflexive tubes made from recycled material, and to a commercial system already certified and consolidated, creating the possibility of comparison. Furthermore, the data acquired in the test environments will be examined in light of the values of solar radiation obtained from a digital meteorological station, such that it is possible to stipulate the lighting capacity of the systems at different times of the year.
Highlights
According to data from the Energy Research Company, the consumption of electric energy in Brazil will be growing by 3.7% per year by 2030
The standards regulating internal lighting in residential and commercial environments that were applied in this study, ABNT NBR ISO-CIE 8995-1, have been in force in Brazil since 2013
The stationperformed performed data recording throughout of and the due day, and characteristic, due to this it was defined that the daily period of analysis will include the interval from
Summary
According to data from the Energy Research Company, the consumption of electric energy in Brazil will be growing by 3.7% per year by 2030. For this reason, it is necessary to constantly increase the energy supply and development of systems with higher efficiency to accompany the increased consumption of electrical energy. It is necessary to constantly increase the energy supply and development of systems with higher efficiency to accompany the increased consumption of electrical energy Besides this indicator, it is observed that the Brazilian territory is geographically between the line of the Equator and the Tropic of Capricorn, and, presents high solar incidence throughout the year [1]. Region of Brazil, which has the worst index, indicating a great potential for solar exploitation in Brazil [3,4].
