How a WELL performance test runs.

Pre-test scoping — 1 to 2 weeks

A 20- to 40-minute call with your WELL AP sets scope: which of the ten concepts are in play, how many measurement zones, calibration requirements, timeline, access logistics. We come off the call with a written scoping note and a firm quote within 48 hours.

What we need from your AP: the project's WELL feature targets, floorplans with zone designations, a main point of contact for site access, and the window when the building is ready (fit-out complete, occupants partially in).

Instrument calibration & import — 1 week before

Every instrument is re-calibrated before shipment. Certificates travel with them. Customs clearance coordinated in advance in each target market; for UAE engagements, instruments are already in-country.

Our standard instrument inventory: particle counters (PM2.5/PM10), CO2 and CO analysers, formaldehyde and TVOC monitors, radon continuous monitors, water-sampling kits for lead / chlorine / bacteria, lux meters (photopic + melanopic), sound-level meters (Class 1), thermal comfort loggers, wet-bulb globe thermometers. All calibrated to ISO or manufacturer-equivalent standards.

On-site — 2 to 5 days

Named lead tester plus one or two support testers. We work zone by zone, following the WELL PV Guidebook's measurement protocol. Daily check-ins with your AP or the project PM, so anything that risks a miss is flagged while there's still time to address it.

If a reading fails a threshold, you hear about it that evening — not three weeks later in the report. This is the single practical move that separates first-pass engagements from retests.

Report — 5 to 10 business days

One deliverable. Cover, methodology, zone-by-zone readings with thresholds, pass/fail, calibration certificates appendix, instrument IDs. Submitted directly to IWBI on your AP's instruction, or delivered to your AP to submit. No narrative, no characterization of the building — the document is an instrument reading.

Performance Verification re-testing

Under WELL v2, Performance Verification requires re-testing every two to three years to keep the certification active. Most clients schedule the first re-verification with us — instrument calibration, zone baselines, and measurement consistency compound in the incumbent's favour.

If something fails

We report what we measure. If a zone fails a concept threshold, the report states the failure, the reading, and the gap to the WELL target. Your AP then leads the remediation decision — it's their scope, not ours. We re-test only the failed feature, on a scoped re-engagement at reduced cost, within 2–4 weeks.
