WELL Concepts
Q4 Addenda

It’s that time of year again, and we’ve been working tirelessly on the Q4 2018 WELL Building Standard™ (WELL™) addenda. The Q4 addenda cycle published feature language clarifications, 22 equivalencies and addenda for WELL Guidebooks. This Q4 addenda cycle includes 5 equivalencies, 24 amendments to WELL Guidebook language and 80 new feature language clarifications for both WELL v1 and the WELL v2™ Pilot as well as 22 amendments for the WELL Community Standard™ pilot.

Addenda are changes and improvements to WELL to help clarify, amend, interpret or provide alternative language for requirements. We allow projects to upgrade any individual feature to any version of the addenda that occurred after their registration date.

Among the changes included in this addenda release, we are 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, including WELL v1, WELL v1 pilot programs, WELL v2 and the WELL Community Standard,  to address questions and points of confusion raised by the WELL user community.

  • Clarifying changes to language in the WELL Performance Verification Guidebook and the WELL Certification Guidebook for both the WELL Building Standard and the WELL Community Standard pilot.

We’ve included an overview below on key components of the Q4 2018 addenda release. To learn more about the addenda process and the changes included in this round, please join us for one of our upcoming webinars on November 7, 10:00 a.m. ET OR 7:00 p.m. ET

Q4 2018 addenda highlights:

Alternative adherence paths

Two new alternative adherence paths were released to provide new pathways for project teams:


  • Feature 65 (Activity Incentive Programs): As one of the two required incentives for this feature, projects may consider an on-site bike pool that enables at least 5% of the project population to reserve or use a bicycle at any time, or exceeds bicycle demand by at least 20%.

WELL Community Standard

  • Feature AQU (Fundamental Air Quality): Added a pathway that allows projects that achieve 9 points related to air quality to use alternate thresholds for the pollutants covered in this feature.


A total of 5 equivalencies have been published in WELL v1: all in the Air concept and all related to VOCs and materials.


Below are some amendment highlights from the Q4 2018 addenda:

WELL v2 Pilot

  • Feature A08 (Air Quality Monitoring and Awareness): Amended based on multiple users' feedback to make sensor requirements more reflective of devices commercially available on the market today.

  • Feature A10 (Combustion Minimization): Amended to exclude rarely-used backup generators – defined as those used less than 200 hours per year - from the emissions criteria.

  • Feature C03: Occupant Survey: Amended Option 2 (Custom Survey) such that thermal comfort questions must ask about two time periods per year but may be asked only a single time per year, rather than requiring the survey to be administered twice per year.


WELL Community Standard

  • Updated concept names from “Fitness” and “Temperature” to align with the WELL v2 concepts “Movement” and “Thermal Comfort,” respectively.

  • Revised to reflect the name and process of "WELL D&O" compared to the "Design Verified" language formerly used.

WELL Guidebooks

  • Reordered and revised the Certification Guidebooks for the WELL Building Standard and the WELL Community Standard to provide more information about WELL D&O and to clarify the steps of certification.

  • Amended the WELL Certification Guidebook to reflect that in WELL v2, the Performance Testing Agents will take the photographs and not the project teams.
