WELL Certification

With the holidays fast approaching, we’re kicking off the celebrations early with the release of the Q4 2017 WELL Building Standard™ addenda. Following up on a robust Q3 addenda cycle that focused on streamlining the WELL Certification process, this cycle shares clarifications for easier interpretation of the WELL Building Standard and several WELL Building Standard pilots.

Addenda are changes and improvements to the WELL Building Standard to help clarify, amend, interpret or provide alternative language for requirements.

Among the changes included in this addenda release, we’re pleased to introduce:

  • Amendments, equivalencies and alternative adherence paths that make it more feasible for projects to achieve WELL Certification.

  • Clarifications to language in the WELL Building Standard and WELL Building Standard pilot programs, as well as the WELL Community Standard.

  • Performance verification guidelines for WELL Building Standard pilot programs including the WELL Community Standard.

We’ve included an overview below on key components of the Q4 2017 addenda release. To learn more about the addenda process and the changes included in this round, our Webinar from Nov. 1 is available for you to view:

Q4 2017 addenda highlights:

Alternative adherence paths

New alternative adherence paths, to provide new pathways for project teams:

  • Feature 39 (Processed foods): For projects that have an existing food and beverage contract in place and are not able to comply with the requirements of Part 1 or Part 2, the project may meet the following requirements:

    • Occupants are educated about the impact of highly processed ingredients and foods through permanent signage displayed on-site or at point-of-decision.

    • Foods that have more than 30 g of sugar per serving and beverages that have more than 30 g of sugar per container have prominent labels at point-of-decision to indicate sugar content.

    Project teams that seek to use this strategy must submit evidence of an existing contractual agreement and are subject to an on-site visual inspection by the WELL Assessor.

  • Feature 58 (Color quality): This AAP provides project teams the option of using light sources with CRI of 85 and R9 of 15 in transient areas. For regularly occupied areas, light sources must meet the requirements of Feature 58 as written.


A total of 17 equivalencies have been published for the following regions:
