DSC창호의 색상별 실내환경 인식조사 연구

In buildings, windows provide lighting, ventilation, and views as a threshold of interior and exterior areas. Not only do windows provide external views and energy, but they also protect people against external weather, noise, and pests. When such roles are combined with DSC (dye-sensitized solar cell), it offers more functions. Unlike existing windows, those with DSC provide the following functions: glare suppression; privacy protection; energy production. If facades are used as a design tool, it offers diverse external designs and more energy. This study intends to explore the feelings of those inside a building with DSC windows as to the lighting environment. It was done as follows. First, DSC windows were installed on the engineering building lab of S University located in J City. Second, data was collected through a survey on the students. The survey was done on 30 graduate school students of S University. The questionnaire consists of the following questions: 2 items on the overall brightness of the indoor environment; 6 items on the illumination; 4 items on the feelings of being inside the building. The collected data was analyzed through SPSS statistical method. The most positive response scored 7 on the Likert 7-point scale. The feelings about the overall indoor brightness are as follows. As for green DSC, brightness scored 4.56 and engaging in activities scored 4.89, above average. As for red DSC, each item scored 4.28 and 3.56 respectively, mostly negative responses. In terms of views, red scored in the range of 2, while green scored between 4 and 5. Thus, green DSC had a positive effect on views. In terms of being ‘pleasant,’ red scored 2.39, which is close to 'unpleasant.' In terms of being ‘comfortable,' green scored 5.06, a highly positive response. In terms of feeling of being inside the building with DSC windows, green scored between 4 and 5. Red, on the other hand, scored between 2 and 3. Thus, green received more positive responses than red. In terms of ‘stability,’ red scored 2.83, indicating it feels unstable. In terms of ‘satisfaction,’ green scored 4.28, a higher score than red. To sum up, green received more favorable responses than red. Afterwards, energy acquisition will be analyzed as to the two colors.
