For Part 1b, remove: "Vertical (Ev) Targets for the 25-65 category in Table B1 of IES-ANSI RP-1-12". Add: "required amount"

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: "Light models or light calculations (which may incorporate daylight) show that at least 250 equivalent melanopic lux is present at 75% or more of workstations, measured on the vertical plane facing forward, 1.2 m [4 ft] above finished floor (to stimulate the view of the occupant). This light level is present for at least 4 hours per day for every day of the year". Add: "At 75% or more of workstations, at least 200 equivalent melanopic lux is present, measured on the vertical plane facing forward, 1.2 m [4 ft] above finished floor (to simulate the view of the occupant). This light level may incorporate daylight, and is present for at least the hours between 9:00 AM and 1:00 PM for every day of the year"

Projects pursuing option a, in place of a letter of assurance and on-site spot checks as indicated in the Performance Verification Guidebook, may provide an annotated floor plan which identifies a subset of workstations that comprise at least 75% of the total number present on site. During Performance Verification, the WELL Performance Testing Agent will restrict sampling to these workstations, and compliance with this feature will be based on 100% of samples equaling or exceeding 200 equivalent melanopic lux.

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To support circadian health by setting a minimum threshold for daytime light intensity.'

For Part 2b, add ", desks and other seating areas" after "Workstations"

For Part 2, add: "one of the" after "...and other seating areas,"

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

Remove: "Less than 20,000 cd/m², including reflected sources: no shielding required". Add: "No shielding required for less than 20,000 cd/m² (including reflected sources)"

Remove: "20,000 to 50,000 cd/m²: 15°". Add: "⍺: 15° for 20,000 to 50,000 cd/m²"

Remove: "Bare lamps and luminaire surfaces". Add: "Luminaires"

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.'

In part description, add: "(excluding lobbies)" after "regularly occupied spaces"

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.

Change “At least one of the following is present for all glazing less than 2.1m [7 ft] above the floor:” to “At least one of the following is present for all glazing less than 2.1m [7 ft] above the floor in regularly occupied spaces:”

In Part 1b, 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 Part 2a, 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.”

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 20 Oct, 2017 AAP, remove: "regularly occupied". Add: "all other"

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.'

For Part 1b, remove: "Walls". Add: "Vertical surfaces"

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…”

Projects may meet the requirements of Feature 62 Part 1b by using the results of daylight modeling to identify and install shading systems to allow the appropriate amount of light into the space. Note that the daylight modeling report submitted must take into account the shades to calculate the light levels in the space during the course of the day.

In 24 Oct, 2016 AAP, add: ", at least" before "2 points"

As an alternative to a lighting simulation to determine the sDA of the space, project teams may use the LEED v4 BD+C EQ Daylight Credit (Option 2 or Option 3) requirements to fulfill the requirement. The provided lighting analysis document must be updated to demonstrate that 90% for Option 2 or 75% for Option 3 of the regularly occupied floor area meets the requirements (i.e., at least 2 points under LEED v4 BD+C EQ Daylight credit).

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 2a, add: "(excluding skylights)" after "All glazing..."

For Part 2a, remove: "(Daylight Glass)", after "from the floor"

Add: "Clearly visible from the building’s main entrance, main entry check-point (e.g., welcome/reception desk), the edge of its main lobby, or edge of its main welcome area, or are located visually before any elevators present upon entering from the main entrance"

Projects that have significantly progressed through or have completed development, design, and/or planning processes may be exempt from Part 2 and may still achieve credit for this feature if achieving Parts 1 and 3. Projects pursuing this AAP are required to submit documentation that demonstrates significant hardship, such as financial or scheduling implications, in order to be exempt from Part 2.

Add: "f. Biophilic elements"

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:"

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).
