Evaluation of the Conditions of Variables Affecting Light Visual Comfort in the Educational Spaces of Polytechnic University of Shahrood

Daylight has a great impact on the quality of indoor spaces, especially educational spaces. In educational spaces, visual comfort along with the use of daylight is of great importance. Therefore, the purpose of the present study is to evaluate the visual comfort in the classrooms.

Two indexes of illumination (lux) and Glare (DGP) were investigated to evaluate the visual comfort in 9 classrooms of 3 faculties from Polytechnic University of Shahrood. Attempts were made to examine at least one sample from each geographical direction. Cases were simulated in Grasshopper software via Honeybee plugin and then analyzed.

The evaluation of the Illumination (lux) index showed that only the class 2 in Mechanical Faculty was in accordance with Standards and in terms of DGP index, class 1 in Engineering Faculty was annoying at 10 and 14 o’clock in February. In the rest of the classes, the glare was due to reflective light and inappropriate lighting angle.

The results of the analysis showed that in the current situation, by making change in the spatial location of variables such as seats place and white board location relative to the position of windows, we can control the shading and better use of shades and light situations and can greatly improve the lighting quality of interior spaces. Also, the most important finding of the research is that the interior design of the space to create the connection between the light source and the layout and white board is not done by experts or is left to uninformed people.
