The “Well Standard” and how lighting helps

Der “Well-Standard” und wie Beleuchtung hilft

Offices and buildings are increasingly being certified with the WELL standard.

The WELL Building Standard, developed by the International WELL Building Institute (IWBI) in 2014, is a certification standard for the design and construction of buildings. The WELL certification aims to promote employee well-being and health in the workplace, based on scientific evidence that the design and interior of a building has an impact on the well-being, productivity and health of its users .

Employees agree on the requirements for a health-promoting workplace: In a 2023 survey in the US, 96% of respondents said there is a connection between the workplace and their productivity. Additionally, 81% of employees agreed that the work environment has an impact on their physical and mental health.

When evaluating according to the WELL Building Standard, various criteria are taken into account, including:

- the air quality,

- the water quality,

- the lighting,

- the acoustics,

- the ergonomics and

- food.

Particular attention is paid to lighting: light output, color rendering, daylight effects and possible flicker effects play a crucial role in assessing whether a building meets the standards or not.

Light is particularly important because it is the main factor in the circadian rhythm, our internal clock. This is synchronized with the natural day-night cycle through various environmental stimuli, with the main signal being light.

Disruption or desynchronization of circadian rhythms has been linked to obesity, diabetes, depression, and metabolic disorders. Since people spend much of their day indoors, inadequate lighting or inappropriate lighting scheduling can lead to a shift in circadian phase, especially when combined with inappropriate light exposure at night.

The problem now is that lighting conditions in most spaces currently focus primarily on visual needs, neglecting circadian rhythm and mental health aspects.

The solution is the WELL Light concept, which aims to create a lighting environment that reduces circadian rhythm disruption, improves sleep quality and has a positive impact on mood and productivity.

There are a total of nine different “features” that define criteria for the right lighting. One of these features is dedicated to circadian rhythms. During this measurement, the light is measured at the user's eye level. This makes it possible to determine how much light actually reaches the eye and is biologically effective there. With many lights on the ceiling, for example, it is shielded by the eyelid and with many desks it is simply swallowed up by a black surface and is not reflected back into the eye.

In addition, the WELL standard stipulates a certain level of “Melanopic Equivalent Daylight Intensity”. It takes into account the spectral composition of light and the sensitivity of the melanopsin receptors in the retina, which are responsible for regulating circadian rhythms.

The connection provided by the WELL standard between measuring the light intensity on the eye and taking into account a melanopic effect factor of the light represents a novelty in lighting planning and shows a rethinking from classic lighting planning towards Human Centric Lighting (HCL).

On the European market, the HEAVN One desk lamp is currently the only solution that supports these requirements of the WELL Building standard through its front-switchable and individually adjustable light component.
This means that the requirements of the WELL standard for office lighting can be easily implemented.

Especially since the HEAVN One offers a number of globally unique features:

1. The combination of full spectrum light, large light exit surface, and ideal angle of incidence ensure a good daylight effect in which enough light falls directly on the retina.

2. Thanks to its three adjustable directions - up to the ceiling, frontally and downwards - the lamp can direct the light specifically to the work area, illuminate the ceiling or create optimal, frontal lighting for the video conference.

3. Thanks to the automatic sun progression, the HEAVN One can automatically change its light colors over the course of the day - between warm and relaxing light colors, to revitalizing and sky-blue light. This supports the circadian rhythm and further strengthens the daylight effect.
