VISUAL COMFORT ASSESSMENT MATRIX LIGHT ENVIRONMENT OPEN PUBLIC SPACE

Abstract

The visual comfort of artificial lighting of open public spaces is an important factor in the sustainable operation of the city. The rapid development of innovations in the field of lighting of the architectural environment has significantly increased the tourist and recreational attractiveness of many cities around the world. However, along with the positive changes, the phenomenon of “light pollution” is a growing concern, a term used to describe excessive artificial night lighting, especially in large urban areas. The effect of light pollution is very noticeable in densely populated cities in Europe, East Asia and North America. All this can have adverse effects on human health. This problem is mainly related to the excessive and uncontrolled "capture" of city lights, advertising media panels, the work of improperly designed street lighting, lighting of stadiums, construction sites, lighting of facades and public spaces. Until now, there is no really effective policy that would solve the problem of light "pollution" of the city [2]. To date, unfortunately, there are no serious government programs and effective plans aimed at regulating the growing light pressure on urban residents. At the same time, visual culture is today one of the main means of human self-identification, and the architect, given this, must have the maximum means and opportunities to create the most effective and consumer-friendly visual solutions. Given this, the study created a hierarchical structure of factors that form the main parameters of visual comfort associated with artificial lighting of public spaces of the city. The purpose of the article is to systematize the factors related to the visual comfort of artificial lighting of open public spaces (PUBLIC SPACE) of the city, which allow to assess the impact of light characteristics of the visible environment on the assessment of its visual comfort.
