Designing High-Performance Commercial Interiors Without Greenwashing

The gap between genuine material sustainability and sustainability marketing has never been more relevant. Here’s what credible specification looks like in practice.
Sustainable design has a credibility problem. Not with the underlying principles — those are well-founded — but with the language used to describe them. “Green,” “eco-friendly,” “sustainable,” “responsible” — these terms appear across product categories without consistent meaning or verifiable backing. For architects specifying on behalf of clients with documented sustainability targets, this creates a real problem.
What Verifiable Sustainability Looks Like
Verifiable sustainability in architectural products comes from third-party certification and documented data. The most relevant frameworks for ceiling specification are Environmental Product Declarations (EPDs), the Declare label program, Red List Free certification, and SCS Global Services certification for recycled content.
Each of these requires independent verification of the claim being made. An EPD documents the life-cycle environmental impact of a product, assessed by a third party. A Declare label documents full ingredient transparency against the Living Building Challenge’s Red List. SCS certification for recycled content verifies the percentage of post-consumer material in a product.
NOWN products carry Declare labels, Red List Free status, and SCS certification. NOWN’s CircuLUM™ aluminium contains 80% post-consumer recycled content — a figure that is documented and verifiable.
Manufacturing-Level Impact
Beyond material content, manufacturing process design affects the environmental footprint of a product. NOWN’s InfiKnit™ 3D knitting process produces each component in its finished geometry, eliminating manufacturing offcuts. This is zero material waste in production — not a claim, but a direct consequence of the process. InfiKnit™ production also uses 40% less water than conventional textile manufacturing methods.
Why This Matters for Specification
Architects who specify products with documented sustainability credentials can support their clients’ sustainability reporting with verifiable data. Architects who specify products based on marketing language cannot. The difference matters as sustainability reporting requirements increase across commercial real estate — both regulatory requirements and client reporting frameworks are moving toward verified data.
