This project suggested incorporating lighting into a lattice installed on the outer wall of a detached house. Because the light resembled light leaking from inside of the house, it was expected to improve the walkability, landscape lighting and crime prevention of the street. First, a lattice mockup was created and various lighting methods were examined. Next, simulation images of the night residential area were prepared and the psychological effects on the streets were evaluated. Based on the experimental results, this lighting method was applied to actual new distribution sites, and it was confirmed that the expected effects could be achieved sufficiently.
