Airscan has been certified as a WELL Performance Testing Organisation (PTO) through IWBI, with certified Performance Testing Agents operating across Europe, Asia and Africa. It’s a formal designation that matters in a specific way: WELL Certification requires on-site performance verification by an approved organisation, and Airscan is now one of them.
What performance testing actually involves
WELL Performance Verification is how a building proves it does what it claims. Rather than relying on design intent or documentation alone, it requires trained specialists to show up on site with professional-grade instruments and run a structured testing protocol across every relevant environmental parameter. Airscan’s PTAs cover the full scope:
- Indoor Air Quality (PA1–PA9)
- Water Quality Management (PW1–PW4)
- Lighting Measurements (PL1–PL2)
- Thermal Comfort (PT1–PT2)
- Acoustic Comfort (PS1–PS5)
The results determine whether a building meets the WELL Building Standard – a performance-based framework that assesses the indoor environment against benchmarks for human health and wellbeing, covering air, water, light, thermal conditions, acoustics, and more.
Why this kind of verification has become more significant
Continuous environmental monitoring – whether through on-site testing or sensor networks – gives organisations an objective picture of how their spaces are actually performing, not just how they were designed to perform. The gap between those two things is often where health risks live. Over the past few years, demand for that kind of accountability has grown: ESG reporting frameworks have raised expectations around health and sustainability credentials, and investors are increasingly asking organisations to demonstrate rather than assert.
WELL Certification sits at the intersection of those pressures. It’s rigorous, internationally recognised, and grounded in measurable outcomes – which is precisely what makes verified testing meaningful. Certification without independent verification doesn’t carry the same weight.
Cross-walking with other green building systems
Airscan also helps clients align WELL with other green building certifications they may be pursuing – BREEAM, LEED, and DGNB among them. These systems share significant common ground, and a well-planned verification process can serve multiple frameworks simultaneously, reducing both cost and complexity for project teams.
Airscan’s PTO status is supported by a team of WELL APs and sustainability consultants who work alongside PTAs throughout the verification process. Check out our Green Building Certifications page to learn more.
