Hotel Designs has released a report that contains an investigation into the positive wellness qualities of circadian lighting. The 14-page document, entitled Circadian Lighting Design, includes analysis and comments from leading experts from in and outside the parameters of hotel design and hospitality.

The contributors were Professor Charles Ceizler from Harvard University; Ari Perala, Founder of Arigami; Paul Robinson, Project Manager at Franklite, Wojciech Miiller, Laboratory and Technical Supervisor at Franklite; Dr Helga Schmid, Author and Founder of Uchronia and artists Sara Bozzini and David Kepron.

The research looks into how colour temperature can be used in hospitality settings to improve moods, increase or decrease energy and optimise sleep performance. In addition, the study highlights the latest technology in lighting design and LED testing. Decorative lighting brand Franklite, which won Best in Tech at The Brit List Awards 2021, contributed to the research, publishing its knowledge on tunable lighting, while also allowing researchers to explore the brand’s very own in-house testing equipment.

Driven by science and new research, the aim of the report is to offer interior designers, architects, hoteliers, technologists and hospitality brands the confidence to include circadian lighting in their designs. Using several lighting case studies and examples of ‘next-level design thinking’ around the wellness benefits of circadian lighting, the research is intended to be a meaningful resource that will help the industry steer itself forward as wellness mega trends evolve.
