WELL Light

TG 10 Wellbeing in Buildings, A BSRIA topic guide, written by Sorcha Redmond and published in January 20205 states:

The WELL Building Standard was developed by the International WELL Building Institute (IWBI a California-registered public benefit corporation) in 2013 and is now a globally recognised standard. It overarchingly aims to create environments that support the physical, mental, and social wellbeing of their occupants.

The WELL Light concept promotes exposure to light and aims to create lighting environments that promote visual, mental and biological health.

It recommends integrating daylight and electric light to create lighting strategies focused on human health, along with traditional requirements for visual acuity and comfort, to deliver healthier and more productive environments.

Context

• The lighting environments where humans spend their time impacts their visual and mental health. Current lighting design practice is generally focused on illuminance levels. Individuals’ visual needs aren’t always met, especially in shared spaces. Circadian rhythms and mental health impacts are rarely considered.
• Light exposure stimulates the circadian rhythms which regulates physiological functions and systems throughout the body’s tissues and organs, such as hormone levels and the sleep-wake cycle.
• Disruption of circadian rhythms has been linked with obesity, diabetes, depression and metabolic disorders.
