WELL Certification

If you are familiar with the WELL Certification process, you know that it includes an on-site Performance Verification element. But you might wonder, what exactly does that cover?

There are three main components to the on-site WELL Performance Verification:

  1. Performance testing: WELL Assessors use specialized equipment to perform various air, water, light, and sound measurements at a number of sampling locations throughout the building or space that is seeking WELL Certification. These results are then compared to the thresholds specified in the WELL Feature requirements. For example, the WELL Assessor will measure total volatile organic compounds (along with other contaminants) at various sampling locations to determine compliance with Feature 1: Air Quality Standards.
  1. Visual Verification: For design elements not included as a part of the documentation review, WELL Assessors will perform a visual inspection to ensure WELL Feature requirements are met. For example, the WELL Assessor will visually check the walk-off system mats to verify the requirements of Feature 8: Healthy Entrance, Part 1.
  1. Spot Checks: While at the building site, the WELL Assessor will conduct random spot checks on selected design criteria previously approved during the documentation review, to visually verify that the feature has been implemented as designed. For example, the WELL Assessor may re-confirm that the air filtration media specified in the Documentation Review is being used in the ventilation equipment.

The Verification Matrix in the WELL Building Standard outlines which Features are verified through WELL Performance Verification versus the Documentation Review.
