WELL Standard Lighting

This section covers each optimisation briefly. If you need full details and requirements of each feature, download our whitepaper.

L3 - Circadian Lighting Design - Optimisation. Max 4 points to be earned

This WELL feature requires projects to provide users with appropriate exposure to light for maintaining circadian health and aligning the circadian rhythm with the day-night cycle.

Our bodies are being kept in sync by various cues, lighting being one of the most important one. As we now spend so much time indoors, the ‘light and dark’ pattern is being disturbed by artificial lighting. Disruption of the circadian system has been linked to serious illnesses like obesity, diabetes, metabolic disorders to name a few. 

WELL currently doesn’t offer any alternatives to submit the accreditation from other systems for Circadian Lighting Design.

L4 - Electric Light Glare Control - Optimisation. Max 2 points to be earned

This WELL feature requires projects to manage glare by using lighting calculation of glare and selecting the appropriate luminaires for the space.

Defined as excessive brightness, glare is managed through the lighting design process. It has been associated with a host of health issues like eye strain or migraine. Reducing glare is vital for visual experience of the occupants in the space.

WELL now offers 2 alternatives to submit the accreditation from other system, Green Star Interiors v1 or Green Star Design and As Build v1. 

 L5 - Daylight Design Strategies- Optimisation. Max 6 points to be earned

This WELL feature requires projects to design spaces to integrate daylight into indoor environments, so that daylight may be used for visual tasks along with electric lighting.

This part highlights the importance of the way the buildings are designed, as the exposure to daylight, or the lack of it, has an enormous impact on the occupants. 

WELL now offers 16 different alternatives to submit the accreditation from other system, like the LEED v4,  BREEAM of Green Star Interiors v1. 

L6 - Daylight Simulation- Optimisation. Max 2 points to be earned.

This WELL feature requires projects to conduct daylight simulation calculations to make informed decisions around fenestration and shading, to provide appropriate daylight exposure for occupants.

WELL now offers 12 different alternatives to submit the accreditation from other system, like the LEED v4, or Green Star Interiors v1 and Green Star Design and As Build v.1.

L7 - Visual Balance- Optimisation. Max 0.5 points to be earned.

This WELL feature requires projects to develop and implement strategies to create a visually comfortable lighting environment. This feature is applicable for all types of environments (commercial and residential dwellings).

Commercial interiors use a mixture of different types of luminaires, including decorative lighting and daylight. Fluctuating light levels impact the visual comfort of occupants and could lead to eye fatigue. Evidence suggests that thoughtful planning of lighting in a space that takes into account colour temperature, daylight and electric light supports a visually comfortable lighting environment. The age of users needs to be taken into consideration to creating a productive space.

WELL now offers 2 alternatives to submit the accreditation from other system, like the Green Star Interiors v1 and Green Star Design and As Build v.1.

L8 - Electric Light Quality - Optimisation. Max 3 points to be earned.

This WELL feature requires projects to consider characteristics of electric light used in the space, such as colour rendering and flicker.

Specifying lighting that uses high quality of light and don’t display signs of flickering contributes to a comfortable and healthy space.

WELL now offers 2 alternatives to submit the accreditation from other system, like the LEED v4

L9 - Occupant Lighting Control. Optimisation. Max 3 points to be earned.

This WELL feature requires projects to implement innovative lighting strategies that take into account personal preferences of users, as well as their interaction with the physical space.

Lighting environments that are customisable by individuals are shown to improve satisfaction levels. The ages of occupants have an impact on the light levels required for visual acuity. Lighting guidelines recommend twice the light levels for individuals over the age of 65 years, compared to individuals between the ages of 25 years and 65 years.
