Indoor Air Quality: A Competitive Advantage for Commercial Contractors

04/30/2026

Across various types of commercial buildings, indoor air quality (IAQ) serves as a top priority for occupants and tenants, building owners, facility managers, and others. While once viewed as more of an afterthought, IAQ has become a prime consideration and an essential expectation in the commercial buildings category. That means key decision-makers ask more detailed questions about IAQ and want clear answers supported by credible proof points. For contractors and their teams, understanding how to respond to these inquiries has become an essential part of delivering successful commercial and industrial projects.

And for good reason as recognition about the health impacts of IAQ has been well-documented. For example, a report from the Occupational Safety and Health Administration (OSHA), Indoor Air Quality in Commercial and Institutional Buildings, states that “OSHA recognizes that poor IAQ can be hazardous to workers’ health and that it is in the best interest of everyone that building owners, managers, and employers take a proactive approach to address IAQ concerns.” The same document notes that the Environmental Protection Agency (EPA) refers to IAQ as one of the top five most urgent environmental risks to public health.

Proactive, Not Reactive, IAQ

As the availability of more information and data has contributed to a growing understanding of the problems associated with inadequate IAQ, contractors who treat it as a reactive concern to address only after a complaint risk falling behind. Waiting until a complaint arises about air quality, occupant discomfort, and related concerns can lead to unnecessary delays, increased costs, and strained client relationships. Instead, contractors need to proactively talk with customers, early and often, about their commitment to IAQ.

Indeed, stakeholders now expect IAQ considerations to be addressed, with evidence, throughout the project lifecycle, including the design, material selection, and installation phases. By considering how building materials, HVAC performance, and insulation systems contribute to the indoor environment from the beginning of a project, teams can help ensure that IAQ goals are taken into consideration and minimize potential risks.

Third-Party Certifications Provide Certainty

At the same time, simply telling a building owner the air is safe isn't enough anymore. For the conversation to be most meaningful, it should go beyond basic reassurances and generalities to include real-world data and documentation that demonstrate results. The contractors who win trust, and protect themselves from liability, are the ones who can back claims about products and other aspects of a building with objective, third-party verification.

These certifications demonstrate that a product has been independently evaluated against recognized standards and performance criteria. Self-reported product claims by manufacturers may provide some degree of helpful context, but they lack the credibility required when questions come up about building materials and their impact on indoor air quality.

Certifications that provide proof of performance include GREENGUARD Gold Certification, which means products have been tested and proven to meet some of the world's most rigorous chemical emissions standards. Products that carry the Asthma & Allergy Friendly® Certified and Verified Healthier Air™ badges have been third-party tested to ensure they reduce allergen exposure and limit pollutants in the indoor environment.

Contractors also should review a manufacturer’s Environmental Product Declaration (EPD), a comprehensive, internationally harmonized, verified document that reports the ways in which a product affects the environment throughout its lifecycle. An EPD includes information about a product’s impact on global warming, ozone depletion, water pollution, ozone creation and greenhouse gas emissions.

Document and Prepare

The contractor who leads with the answer leads the IAQ conversation. Walking into a pre-construction meeting with IAQ documentation already in hand does more than answer a question. It demonstrates a level of professionalism that can contribute to efficient project approvals up front and reduce time-consuming callbacks later, helping to build strong client relationships and generate referrals.

Preparation is the differentiator for contractors. Knauf Performance+® products, with numerous IAQ and related certifications, make that preparation effortless. Contractors who prioritize transparency, documentation, and preparation will stand out in today’s commercial buildings market that prioritizes IAQ.
