Educational buildings have lighting as one of the main end uses in the consumption of electricity with significant potential for the integration of natural and artificial lighting systems. The Inmetro Normative Instruction for Energy Efficiency Classification of Commercial, Service and Public Buildings (INI-C), published in September 2022, evaluates, among other items, the energy efficiency of the electric lighting system and its integration with natural lighting. The present study compared the potential of integration of natural light by simplified and simulation methods according to the methodology proposed in a higher education building. It was concluded that, although both generate the same classification for the lighting system, the simulation method results in larger areas for the primary zones of natural lighting. As these zones may include more than one row of luminaires from the opening, it is suggested that this zone be divided into lines parallel to the opening.
