Aging Effect of External Building Materials by Image Analysis

通过图像分析，明确了外墙建筑材料老化效应的基本性质。研究内容和结论如下。（1）利用模拟图像对建筑立面印象的评价方法建筑立面的印象影响景观评价。近年来，利用监视器图像对建筑物立面的模拟得到了很好的研究，但对实际建筑物的评价与模拟图像的评价之间的关系尚不清楚。在这项研究中，通过使用实际的建筑物和通过使用监视器上的模拟图像来评估在不同的观察距离下观察到的建筑物立面的印象。结果，清楚的是，监视器的评估值和实际建筑物的评估值的相关性高，并且随着观察距离变远，对建筑物立面的好感的印象变高。（2）建筑外立面材料观感的模拟与检测评价建筑外立面材料的观感影响着整个景观，因此建筑外立面材料不仅要具有耐久性，而且要考虑周围环境条件设计出舒适的外观和色彩协调。本研究旨在探讨砖砌体的颜色特性与年龄及其他视觉品质的主观评价之间的关系。通过感官测试的结果，阐明了色彩搭配对建筑物外观老化和美观的影响，并将其系统化，为建筑物外观的长期管理提供依据。

Fundamental properties of the aging effect of external building materials were cleared by image analysis. The contents and conclusions are shown in the follows.(1)Evaluation method on the impression of building facade by using the simulated imageAn impression of building facade influences a landscape evaluation. In recently, an simulation of building facade by using monitor image is well investigated, but it is not clear that the relationship between the evaluation of an actual building and the evaluation of a simulated image. In this study, the impression of building facade observed by various observation distances was evaluated by using an actual building and by using a simulated image on the monitor. As a result, it was cleared that the correlation of the evaluated value by a monitor and by an actual building was high, and the impression on the favor of building facades became high as an observation distance becomes far.(2)Evaluation on the Impression of Building Facade Materials by Simulation and ExaminationImpression of building facade affects a total scene of landscape, so building external materials should have not only a durability performance but also a comfortable appearance and color coordination designed by considering surrounding environmental condition. The purpose of this study is to examine the relationship between the color properties of brickwork and the subjective evaluation of age and other visual qualities. The influence of color coordination on aging and appeal is clarified through the results of sensory tests and systematized for the long-term management of building facades.
