【 摘 要 】

Indoor lighting is one of the most important consumer of the energy worldwide, driving to a high GHG emissions. Current state of the lighting system in the classrooms of the Technical University of Ambato (UTA), Tungurahua, Ecuador has been assessed in this work. A sample of classrooms were selected to quantify its illumination levels, with the Luxometer (Sper Scientific 850007), these data were computed by means of DIALUX software, whose generates the light distribution of different lighting systems scenarios and the lamps geometric distribution. Number of luminaires, luminous distribution and the energy efficiency value of the installation (VEEI) were compared among all the different cases, also a luminance analysis and the energy efficiency of installation was performed. First results show an important reduction of around 40% of the energy at present consumed, decreasing the emission of almost 200 tons of CO2 equivalent per year.
