Do you need WELL or Fitwel certification? A consultant’s honest take
a biophilic study area designed by Biofilico for Carnegie Mellon University Qatar following healthy building principles
There's a version of this article that a certification body might write as part of its communication plan — one that makes the case for why every building should pursue formal healthy building accreditation, lists the benefits, and ends with a call to register. This is not that article.
As both a WELL Advisor — holding credentials for the Movement and Mind chapters — and a Fitwel Ambassador, I've guided clients through this decision on projects across Europe and the Middle East. And the honest answer, more often than people expect to hear from someone with these credentials, is: it depends. And sometimes, the answer is no. But just as importantly, both WELL and Fitwel have upped their game recently and now offer even more bang for the buck.
So, here's the framework I like to use when a real estate developer client or hotel owner asks whether they need a WELL certification, Fitwel or neither.
First, understand what each standard is actually doing
Before the question of whether to certify, it helps to understand what you're certifying against — because WELL and Fitwel are doing meaningfully different things, despite being regularly lumped together.
IWBI WELL is built around the premise that the built environment has a direct and measurable impact on human health. The WELL Building Standard organises requirements across ten concepts — Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind and Community — with mandatory preconditions and optional optimisations that earn points toward Silver, Gold or Platinum ratings.
The underlying logic is data-driven: our bodies react to the quality of the air we breathe, the water we drink, the light we see and the sound we hear. Performance is verified by third-party testing on site. It is not a documentation exercise — it is a genuine performance standard with teeth.
Fitwel was created by the Centers for Disease Control and Prevention and the General Services Administration with a different starting point: evidence-based design strategies applied through a scorecard model. Rather than on-site performance verification, Fitwel works on a documentation and submission basis. This distinction is crucial.
It provides an accessible entry point for organisations to incrementally strengthen commitment to workplace health and productivity. Teams accumulate points toward a one, two or three-star rating by demonstrating strategies are in place — not that specific thresholds have been met in testing.
The practical difference: WELL is more rigorous, more demanding and carries stronger third-party validation. Fitwel is more accessible, faster to complete and better suited to portfolio-scale commitments or projects where the timeline and budget don't support a full WELL process. Both are useful tools. Neither is universally necessary.
The question I always ask first
Before recommending either standard, I ask one question: who is this certification actually for?
The answer shapes everything that follows.
If it's for your tenants or buyers — people who will make leasing or purchasing decisions partly based on the health credentials of the building — then the public visibility of the certification matters.
WELL's stronger brand recognition in the European commercial real estate market is relevant here. WELL-certified buildings are in high demand by tenants, and studies indicate certification can contribute to meaningful improvements in employee productivity and reductions in absenteeism.
For a corporate headquarters, a flagship office development or a major mixed-use asset where wellness positioning is central to the commercial story, WELL's rigour and visibility are the point. The plaque on the wall is doing real work.
If it's for your own organisation — an internal commitment to improving building performance, a baseline for ESG reporting, a structured way to embed occupant health into a development pipeline — then Fitwel's accessibility and flexibility may serve you better. Standard certification review runs within sixteen weeks from submission, with expedited timelines available for Champions and Ambassadors.
For a landlord managing a diverse commercial portfolio who wants consistent health credentials across multiple assets without the cost and complexity of WELL on every building, Fitwel scales in a way WELL doesn't.
If the honest answer is neither of the above — if wellness is about design quality and occupant experience rather than external validation — then the conversation should be about healthy building principles applied directly to the design brief, not about which framework to register on.
The cost reality
This conversation always gets more concrete when fees come up.
For a project team encountering WELL for the first time, the documentation burden alone — which is substantial — tends to generate additional consultant hours that aren't always anticipated in early budget discussions.
Fitwel is significantly more accessible. Certification fees start at $7,500 for workplace, multifamily residential, retail and senior housing projects, scaling with square footage, with a $500 registration fee per building. The physical and operational changes required to score well on Fitwel can range from minimal to significant depending on the starting point — but the framework itself doesn't mandate the level of capital investment that WELL preconditions can require.
Cost comparison only tells part of the story though. The more meaningful question is what you're spending on design changes, systems upgrades and consultant time on top of the certification fees themselves. A WELL-certified office typically involves real investment in air quality systems, acoustic performance, lighting design and materials specification. A Fitwel-certified building may require far fewer physical changes, particularly if the design brief is already oriented toward occupant health.
When neither is the right answer
This is the part of the conversation that doesn't appear on certification body websites.
There are projects — particularly in luxury hospitality, bespoke residential and specialist wellness venues — where the design brief already exceeds what either standard would require, and where formal certification adds process overhead without meaningful design benefit. The wellness specification is more demanding than the standard. The healthy materials strategy is already more rigorous. The IAQ monitoring, circadian lighting design and acoustic performance are already there.
In those cases, the more useful approach is to apply healthy building principles directly to the design decisions that matter: air quality, materials specification, acoustic performance, lighting, thermal comfort and occupant experience — without layering a certification framework on top. The outcome for the person using the building can be identical. The value is in the quality of the design, not the third-party sign-off.
A practical decision framework
If you're currently weighing up healthy building certification for an upcoming project, here's how I'd suggest thinking through it:
Pursue WELL if: your primary audience is corporate occupiers or tenants for whom WELL is already a recognised procurement signal; you have the budget, timeline and consultant resource to do it properly; and the wellness narrative is central to how the building will be positioned and marketed.
Pursue Fitwel if: you're managing a multi-asset portfolio and want consistent health credentials at scale; your project timeline or budget doesn't accommodate WELL; or you want a structured framework to improve building performance incrementally with a clear, documented baseline.
Skip certification and focus on the design if: the wellness ambitions of the brief already exceed what either standard requires; the project type — a boutique hotel, a luxury residence, a bespoke wellness venue — doesn't benefit from third-party certification as a commercial signal; or the timeline and budget make formal certification impractical.
In any of these scenarios, the underlying design principles are the same. Healthier air, better light, calmer acoustics, considered materials, spaces that support movement and restoration — these deliver value to occupants whether or not a certification body has verified them.
The certification is a useful tool when it serves the project. It's overhead when it doesn't.
A note on dual credentials
One of the less-discussed aspects of this landscape is that relatively few consultants operating in Europe and the Middle East hold both WELL Advisor and Fitwel Ambassador credentials. Working across both frameworks means the advice I give clients is comparative rather than partisan. I'm not positioned to advocate for one standard over the other, and the recommendation always follows the project logic rather than a preferred framework.
If you're currently working through this decision for an upcoming project, it's exactly the kind of conversation we have at the start of every workplace or commercial brief. Feel free to get in touch.
