Crowne Plaza Hotels Pilot Circadian Lighting

March 22, 2019

InterContinental Hotels Group has partnered with Healthe by Lighting Science to pilot the use of state-of-the-art circadian lighting in its Crowne Plaza hotels. 

Crowne Plaza Atlanta Airport will be the first IHG property to install the Journi task light luminaires in guest rooms. Designed using Healthe’s patented GoodDay and GoodNight spectrum technologies, Journi enables users to access the alertness and focus-enhancing spectrum during the day, and then easily change to the warm, sleep-enhancing spectrum at night. This dual-spectrum luminaire can help you to effortlessly bring energy-efficient, circadian lighting right to your hotel room. Ultimately, Journi also helps to regulate the body’s circadian rhythm or 24-hour internal body clock, which affects such biological functions as sleep, hormone levels, body temperature and metabolism.

Two dual-spectrum luminaires are installed in each room. The luminaires feature proprietary technology that adds and removes the blue 480 nanometers wavelength of light — believed to be the key wavelength of light that impacts on the circadian rhythm — to achieve optimal biological benefits. Adding the blue 480 nanometers wavelength boosts alertness (photo above). Removing it signals it’s time to prepare for sleep (photo below).
