태양광 방음벽 디자인 분석 및 CIGS기반 가설방음벽 디자인 개발 연구

(Background and Purpose) Noise barrier walls refer to noise suppression facilities installed to protect the surrounding environment such as residential facilities or public facilities from noise, and are one of the essential elements in configuring the facility environment to suppress noise. A certain level of height is required to meet the noise control standards, which has a problem with not only the view of the surrounding environment and the disturbance of the right to sunlight but also as a significant obstacle to urban beauty. The purpose of this study is to conduct a design analysis according to the installation environment and function of domestic and foreign solar noise barrier walls, identify the requirements, and develop a modular noise barrier wall using CIGS thin film solar cells based on the analysis results to propose a design that can improve the problems of viewing areas and disturbance of the right to sunlight, and aesthetics. (Method) First, the theoretical background was reviewed through literature research, and design elements to be analyzed were derived through analysis of the noise barrier wall design guidelines, and functional elements were analyzed according to the aesthetics and environment of domestic and foreign solar noise barrier wall designs according to the selected design analysis criteria. (Results) As a result of the analysis, the appearance type was 3 types of mixed type and 2 types of single type, and the mixed type capable of complex functions tended to be preferred. Most of the photovoltaic cell materials were opaque silicon and were dark blue. Opacity and dark colors show that it is difficult to use visually free colors, and there is a problem of blocking pedestrian vision, so improvement was required. It was confirmed that all of the structure of the noise barrier walls was upright, and structurally, a single species lacked adaptability to various situations. Most of the installation environments with noise barrier walls were installed around highways, so there was a lack of analysis based on actual construction sites or living environments, and most of them had only basic energy production and soundproofing functions. In addition, it was found that efficient installation convenience and production cost were important in terms of maintenance. (Conclusions) Based on the results of the analysis, the actual construction site was selected to identify the requirements for the installed noise barrier wall, and based on this, the noise barrier wall was designed and developed with a parametric technique using 3D design tools, Rhino and Grasshopper. The research and analysis contents and the developed design results will be evaluated and tested using 3D rendering tools and code-based analysis tools to use solar soundproof walls as evidence for design development, focusing on living spaces in the future.
