Outline of Final Research Achievements

To clarify textures of building interior and exterior finishing material quantitatively, luminance imaging analysis and actual measurement survey in real buildings were carried out.
First, with brightness images from captured photos in several shutter speeds, it was suggested that textures without a unique color tend to harmonize as a result of subjective experiments.
Next, we conducted actual measurement surveys on domestic and international architecture. It was suggested that there were many white plaster and low-gloss finish, and that the roughness of the surface could be grasped by the brightness distribution with a certain area measurement. In the measurement of white silkscreen glass, the brightness contrast varies depending on the light shielding ratio, and it was found that it is possible to estimate the interior light environment by image simulations.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果から，内外装材のテクスチャーを作成し，光環境条件を設定したシミュレーションによって，室内外の光環境や見る人の視点による見えを予測して室内視環境をシミュレーションできることがわかった。本研究では，幾何学的に作成できるテクスチャーを用いたが，今後は，曲線等を用いたランダムなテクスチャーを作成することで，幅広く室内視環境設計に対応することができると考えられる。
