Circadian lighting design

Intent:

To support circadian health by setting a minimum threshold for daytime light intensity.

Post Date: 27 Apr, 2017 Status: Approved 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 Assessor 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.
Post Date: 17 Jan, 2017 Status: Approved 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.
