Analysis of the Illuminance Level in a Classroom for Differnt Sky Condition

Abstract

Nowadays, due to the decrease in renewable energy sources on a global scale, studies for the effective use of energy and reducing energy consumption gain importance. Buildings have an extremely important role in energy consumption. Educational buildings, which are used for educational purposes, are important in terms of both the duration of use and the comfort level of the user. While the aim in educational institutions is to increase the level of user comfort, the main target is to increase the efficiency in educational activities. In energy consumption, the rate of consumption due to lighting is quite high. For this reason, effective and appropriate design of natural and artificial lighting is important in terms of both user efficiency and minimizing energy consumption. In lighting design, natural and artificial lighting should be considered in an integrated manner. The design should be started by considering daylight as the primary energy source. The homogeneous distribution of light in the space is as important as the average illumination level in the classroom. The light should spread homogeneously in the space in a way that provides equal efficiency to every user. In this study, the illuminance level of a selected classroom in Niğde Ömer Halisdemir University Faculty of Architecture was analyzed. In the selected workshop, measurements were made in the 5 weeks selected in November and December, at different times of the day and in different sky conditions, when the artificial lighting elements were on and off. In the case of the lamp on, generally sufficient average illuminance level can be met in all measurement hours, while it has been observed that sufficient average illuminance level is provided by turning on the lamps in the cloudy sky condition.
