In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To support visual acuity by setting a threshold for adequate light levels and requiring luminance to be balanced within and across indoor spaces.'

Add: "During Performance Verification, EML is measured on the vertical plane at eye level of the occupant." after "The biological effects of light on humans can be measured in Equivalent Melanopic Lux (EML), a proposed alternate metric that is weighted to the ipRGCs instead of to the cones, which is the case with traditional lux."

Remove: "At least one of the following requirements is met". Add: " Light models or light calculations demonstrate that at least one of the following requirements is met"

Remove: " For all workstations, electric lights (which may include task lighting) provide maintained illuminance on the vertical plane of equivalent melanopic lux, greater than or equal to the lux recommendations in the Vertical (Ev) Targets for the 25-65 category in Table B1 of IES-ANSI RP-1-12. For example, Reception Desks are provided with 150 equivalent melanopic lux from the electric lights". Add: "For all workstations, electric lights (which may include task lighting) provide maintained illuminance on the vertical plane of 150 equivalent melanopic lux or greater. Projects may use the lux recommendations in the Vertical (Ev) Targets for the 25-65 category in Table B1 of IES-ANSI RP-1-12 in place of 150"

To increase the delivered Equivalent Melanopic Lux and fulfill Feature 54, projects may provide task lighting at workstations upon request. Projects choosing to pursue this option must demonstrate that they have sufficient funding to procure task lighting for at least 75% of the total workstations within the WELL boundary. Projects must also provide comprehensive education to employees that focuses on the benefits of task lighting and circadian lighting overall.
Note that during the Performance Verification, the project must provide a sample of these task lights and coordinate the placement and the power source at each applicable workstation prior to the lighting measurements. A sufficient number of task lights should be provided so as to not impede the site visit schedule.

In Part 1b, change “For all workstations, electric lights provide…” to “For all workstations, electric lights (which may include task lighting) provide…”

In part heading, Remove: "Lamp". Add: "Luminaire"

Remove: "50,000 to 500,000 cd/m²: 20°". Add: "⍺: 20° for 50,000 to 500,000 cd/m²"

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To minimize direct and overhead glare by setting limits on the luminous intensity of luminaires.'

The following glare control strategies may be used in lieu of glare requirements for atriums. Project teams may submit a plan or narrative detailing the use of a combination of the following: glare reducing film that has a solar transmittance of 10% or less, space planning to ensure workstations are set back from atrium spaces by at least 7 feet, and building orientation to reduce solar glare. Project teams must demonstrate that occupant comfort is not impacted.

In the Feature description, remove the second paragraph. Replace with the following text:
Intent: 'To avoid glare from the sun by blocking or reflecting direct sunlight away from occupants.'

In Part 1a, change “Interior window shading or blinds that are controllable by the occupants or set on a timer” to “Interior window shading or blinds that are controllable by the occupants or set to automatically prevent glare.”

Change “At least one of the following is required for all glazing greater than 2.1 m (7 ft) above the floor:” to “At least one of the following is required for all glazing greater than 2.1 m (7 ft) above the floor in regularly occupied spaces:”

In Part 2b, change “External shading systems that are controllable by the occupants or set on a timer.” To “External shading systems that are set to automatically prevent glare.”

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To minimize visual discomfort by situating computer monitors in a way that avoids glare and luminance contrast.'

Inquiry: Can “free address” workstations, allowing occupants to change workstations to avoid glare, be used to meet the feature requirements?

Ruling: No, free address workstations may not be used to meet the feature requirements.

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To enhance spatial aesthetics and color differentiation through the use of lamps with quality color rendering abilities.'

In the Feature description, remove the second paragraph. Replace with the following text:

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To prevent glare and encourage reliance on natural light through automated shading and dimming.'

Add MEP Letters of Assurance as required documentation, remove Architect Letters of Assurance.

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To promote exposure to daylight and views of varying distances by limiting the distance workstations can be from a window or atrium.'

In Part 2a, change “75% of all desks or regularly occupied seats…” to “75% of all workstations…”

BREEAM UK New Construction 2014, Credit Hea 01: Visual comfort, criteria 3a or 3b has been approved to comply with F62 of the Multifamily Residential Pilot.
Note that projects are required to include bedrooms in addition to kitchens, living and dining rooms, when pursuing option 3a or 3b.

The Green Star Daylight criterion is deemed partially equivalent to the requirements of Feature 62. Compliance with the Green Star credit is sufficient to comply with Part 1a of the WELL feature. 

Inquiry: Can an automatic shading system that draws shades when sensors indicate that daylight can contribute to glare at workstations be used in lieu of meeting the feature requirements?

Ruling: No, the installation of automated shading devices alone does not meet the feature requirements, as this feature requires demonstration that as a result of the overall lighting design, the project is able to achieve the proper amount of daylighting.

For Part 1b, remove: "(Daylight Glass)", after "above the floor"

For Part 2b, remove: "(Vision Glass)" after "from the floor"

Remove: ", including, decorative painting" after "Artwork"

Change the first line of Part 3 from "Both common stairs and paths of frequent travel display elements of aesthetic appeal in incorporating at least 2 of the following:" to "In projects of 2 to 4 floors, common stairs, entryways and corridors display elements of aesthetic appeal by incorporating at least 2 of the following:"

Change “In projects of 2 to 4 floors, at least one staircase meets the following requirements:” to “In projects of 2 to 4 floors, at least one common staircase meets the following requirements:”

Staircases located in residential units may be exempt from meeting the requirements of Part 2c (stair width set at a minimum of 1.4m [56 in] between handrails.
