Human centric lighting in hotel facilities`s interiors

Abstract

The article describes the features of Human centric lighting and it`s application in hotel facilities`s interiors and aims to proof feasibility of human centric lighting application in hotel facilities`s interiors

In modern society, humans spend over 90% or their time indoors. However, despite the growing scientific understanding of the impact of light on biological mechanisms, benefits of this understanding are not harvested in practical systems. Existing light in the built environment, offices in particular, is designed predominantly to meet visual performance requirements. Increasing attention is being given to the biological effects of light, especially how it could be used to promote occupants’ health and well-being through the circadian functions that regulate sleep, mood, and alertness. HCL is used to describe lighting that, considering both visual and non-visual effects of light, aims to enhance the biological and emotional health and well-being of people. Several characteristics of lighting, including quantity, spectrum, timing, duration, and distribution, determine its nonvisual effects on our bodies and minds.

Artificial light can be exploited as a means to modulate sleep‐wake schedules and re‐align the internal clock with the environment by phase‐shifting the biological clock. This ability can be used in hotel facilities in order to minimize implications of jet lag in tourists. It is also reasonable to implement human centric lighting systems predominantly at hotel facilities designed for long term stay.
