Viewerphilic nightscape based on correlated color temperature

Abstract

Nowadays, many factors are involved in lighting design to achieve targeted lighting in addition to meeting the user's requirements and security to avoid energy loss. As building indexation at night is one of the main reasons for building lighting, it is necessary to make a decision to reduce energy consumption and increase observer's attention. The present study investigated the relationship between the correlated color temperature of the background and building based on the amount of visual attention and the amount of visual desirability. In this article, using a factor analysis approach, a range that attracts visual attention and visual desirability at the same time was obtained, and it is called viewerphilic perspective. The results presented in the form of a diagram show a relationship between the variables that directly and indirectly influence the formation of a viewerphilic night perspective. The results showed that the elements with a high correlated color temperature in the background and a low correlated color temperature and neutral color were in the viewerphilic range, while the elements with a low color temperature and a background with a high color temperature was in the range of viewer phobic.
