Preliminary results on integrative lighting in classrooms: simulations and field measurements

The paper presents results from a study on integrative lighting for real middle school classrooms located in a school building in Turin, Italy, considering the contribution of both daylighting and electric lighting. The research addressed two main objectives: (i) to verify if the circadian values (melanopic equivalent daylight illuminance m-EDI) calculated or measured in the classrooms could meet the reference values reported in recent literature, for instance in the WELL protocol; ii) to assess the influence on integrative lighting (photopic and melanopic illuminances) played by the electric lighting and daylighting and, for this last condition, analyzing the impact of different room orientation and sky conditions.
