Remove: "The way brightness is distributed across ceilings in a given room". Add: "The way brightness is distributed across ceilings in a given room that maintains lighting variety but avoids both dark spots, or excessively bright, potentially glaring spots. For example, projects may establish that, while still maintaining lighting variety, one part of the ceiling cannot be 10 times greater or lesser luminance than another part of the ceiling in the same room"

Remove: "Brightness contrasts between task surfaces and immediately adjacent surfaces, including adjacent visual display terminal screens". Add: "Maximum brightness contrasts between task surfaces and immediately adjacent surfaces, including adjacent visual display terminal screens.

For Part 1b, add: "facing forward (to simulate the view of the occupant)" after "vertical plane"

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 or other supplemental lighting at workstations upon request. Projects choosing to pursue this option must demonstrate that they have sufficient funding to procure task or other supplemental 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 or other supplemental lighting and circadian lighting overall.
Note that during the Performance Verification, the project must provide a sample of these task or other supplemental lights and coordinate the placement and the power source at each applicable workstation prior to the lighting measurements. A sufficient number of task or other supplemental lights should be provided so as to not impede the site visit schedule.
