친환경건축물의 실내공기질 (TVOC, HCHO) 평가방식 개선을 위한 예측방정식 개발에 관한 연구

The majority of certification systems evaluate indoor air quality by the considering the factors affecting the indoor air quality (e.g. interior architecture finishing, the possibility of bake out, ventilation rate, etc.) as individual items. These individual evaluation methods considering individual factors, offer a simple method for a rapid evaluation of indoor air quality during the planning stage of the method. However, these evaluation methods make it difficult to grasp the degree of overall improvement in the indoor air quality, and they cannot accurately reflect how much each of these items contribute to the indoor air quality improvement in terms of their weighted values. Although a number of programs have been developed for the evaluation of indoor air quality, they cannot perform rapid calculations because of being too complicated and requiring various input values. Hence, in this study, we aim to develop a certification system with a simple equation that can be used for an overall evaluation of the indoor air quality. To set up a variable to be input in the equation, the factors examined for the analysis included: wall/ceiling paper, adhesive for wall/ceiling paper, floor material, adhesive for floor material, and ventilation rate. The experimental design which helped us identify the main factors, among the main factors, with a minimum number of experiments was used as a measure to decrease the number of experiments. The indoor air quality scenarios were simulated using a validation equation, and the results of the simulations were used as data for multiple regression analysis for the development of load prediction equations.
