Simulation of retrofitting of ligthing system of an academic building for energy savings

Abstract

This paper presents a brief overview of a simulation of a retrofitting of the lighting system of an Academic Building for energy savings using Rhinoceros and Energy Plus software. The proposed simulations have the main objective of finding the correct distribution and amount of lamps to be installed in a classroom, taking into account the existing standard in Mexico. Using Energy Plus software a set of simulations were performed to evaluate the energy consumption of the actual lighting system, and the LED-based retrofitted lighting system. Lighting is the second important load in offices and/or classroom buildings. The proposed simulations provide information of the amount of lamps needed to accomplish with the legal normative and the number of energy savings obtained with the replace of the fluorescent lamps by LED lamps.
