What Does GREENGUARD Gold Actually Mean - and Should Your New Home Have It?

The Air Inside Your Home Might Be Worse Than the Air Outside

The EPA has consistently found that indoor air can contain pollutant concentrations two to five times higher than outdoor air. In newly constructed homes, that number can spike even higher during the first year after construction, as building materials release volatile organic compounds (VOCs) through a process called off-gassing.

VOCs are chemicals emitted as gases from materials like paint, flooring adhesives, composite wood products, sealants, and insulation. Exposure can cause headaches, eye and throat irritation, and long-term respiratory issues. Some VOCs – including formaldehyde, commonly found in engineered wood products – are classified as known carcinogens.

This is not an abstract risk. It’s happening in millions of homes right now, and most homeowners have no idea.

What Is GREENGUARD Gold?

GREENGUARD Gold is a third-party certification administered by UL Environment that tests building products for chemical emissions. Products that earn GREENGUARD Gold certification have been verified to meet some of the most stringent chemical emission limits in the world – standards originally developed for sensitive environments like schools and healthcare facilities.

The certification covers total VOCs, individual VOC compounds, and formaldehyde emissions. It requires ongoing annual testing, not just a one-time check. Products must continue to meet the standard to maintain certification.

This matters because the label "low-VOC" on a paint can or flooring box is largely unregulated. A product can claim to be low-VOC while still emitting chemicals at levels that affect sensitive individuals. GREENGUARD Gold provides an independent, verified baseline.

What Does This Look Like in a New Home?

In most new construction at the entry-level price point, builders use whatever materials meet code and fit the budget. The paint is standard contractor-grade. The flooring adhesive is whatever the installer carries on the truck. The composite wood in the cabinets may contain urea-formaldehyde binders. None of this violates any law. All of it contributes to indoor air pollution.

A home built to GREENGUARD Gold standards from the inside out uses zero-VOC paint, tile and luxury vinyl plank that have been independently tested and certified, and materials selected specifically because they do not off-gas harmful chemicals. When that standard extends to every surface – from the interior finishes to the exterior Hardie board siding and roofing materials – you create an environment where the air quality is measurably better from day one.

Does It Cost More?

This is the question most buyers assume they already know the answer to. The reality is more nuanced. Zero-VOC paint costs marginally more than standard contractor-grade paint – often the difference between a $200 and $300 line item on a full home. Certified flooring and tile products exist at every price point, including entry-level. The cost difference on any individual material is typically modest.

What changes the equation is the commitment to specifying and sourcing every material to meet the standard. That requires a builder who treats material health as a design decision, not an afterthought. It means cataloging products, verifying certifications, and making deliberate choices at every stage of construction.

Most builders don’t do that – not because the materials are prohibitively expensive, but because the process requires intention and discipline.

The Right Question to Ask Your Builder

If you’re considering a new construction home, ask the builder what standards their interior materials meet. Ask specifically about VOC levels in the paint, the formaldehyde content of the cabinet materials, and whether the flooring carries an independent air quality certification.

The answer will tell you a lot – not just about the home, but about the builder’s priorities.
