Analysis of EnergyPlus daylighting module results – A Brazilian case

This article aims to discuss the results of the EnergyPlus daylighting module – Detailed. Because of the program relevance among the brazilian researchers and the high potential for daylighting in Brazil, it is important to evaluate whether their models for calculating daylighting are appropriate for the brazilian conditions. EnergyPlus results were compared with data measured in situ, of daylit room with windows on two parallel façades. The simulation results show weak correlation between the model output and the measured data. The illuminance levels and distribution obtained in simulations were not consistent with the measured values.
