The Influence of Glazing types on improving daylight factor and reducing glare in classrooms based on numerical simulations

Classrooms with double-sided windows in southern China lack good measures to improve the daylight factor and reduce glare due to large windows, so the lighting indoor environment is usually uncomfortable due to the high glare and uneven distribution of daylight on sunny days. Based on the digital simulation of the light environment, this paper studies the effect of the properties of 5 types of glass material in improving the factor of daylight and daylight glare. First, a classroom was chosen as a research object and the evaluation parameters (daylight factor and glare) were measured. Secondly, a simulation model was created and the measured and simulated data were compared to verify the validity of the data. Five types of glass were selected and their effect was studied to improve the daylight factor and reduce glare. simulation Results show that: The degree of transmittance of glass technologies has a significant impact on the improvement of classroom lighting and the daylight factor. Controlling the degree of transmittance of the glass results in a greater degree of glare control and thus improved visual comfort. The computer numerical simulations used in this research assisted to a high extent in providing a prediction model to study the effect of glazing techniques in improving the daylight factor and reducing the glare.
