English term or phrase:ηm
The UNI 10840 regulations "Scholastic Classrooms – General criteria for artificial and natural light" indicate requirements for natural light. Set values for the average daylight component ηm must be guaranteed for the larger part of the classroom >= 3. This value is subject to the reflection index of the internal walls, the dimensions of the clear glass surfaces, the characteristics of the glass (including its levels of luminous transmission), and the window variable.
The central sentence in Italian: "devono essere garantiti determinati valori del fattore medio di luce diurma ηm, per la maggior parte delle aule >= 3."
