When you walk into a newly built home or commercial building, that “new building smell” might seem like a sign of freshness and modern design. In reality, it can be a warning sign of something less welcome: volatile organic compounds, or VOCs. These chemicals are commonly released—or “off-gassed”—from materials used in modern construction, and can have a significant impact on your indoor air quality.
Understanding the role of VOC in construction is essential for anyone living in, working in, or managing a new building. From paint and flooring to adhesives and sealants, many standard building materials emit VOCs long after the structure is complete. If not addressed, these emissions can contribute to various health concerns and reduce the comfort and safety of your indoor environment.
What Are VOCs and Where Do They Come From?
Volatile organic compounds are a group of carbon-based chemicals that evaporate easily at room temperature. While some VOCs are naturally occurring, many found in buildings are man-made and originate from everyday materials. You’ll find VOCs in:
- Interior paints and finishes
- Carpets and vinyl flooring
- Composite wood products (like particleboard and MDF)
- Adhesives and caulks
- Insulation materials
- Varnishes and sealants
- New furniture and cabinetry
These materials release VOCs as they cure or settle into the indoor environment. The off-gassing process can continue for weeks or even months after construction or renovation is completed.
Health Effects of VOC Exposure
Exposure to VOCs can cause both short- and long-term health effects, especially in enclosed or poorly ventilated areas. Immediate symptoms may include:
- Headaches
- Eye, nose, or throat irritation
- Dizziness or nausea
- Fatigue
- Worsening of asthma or respiratory symptoms
Prolonged or repeated exposure to certain VOCs, such as formaldehyde or benzene, can increase the risk of more serious conditions, including organ damage or cancer. Children, elderly individuals, and people with pre-existing health issues are especially vulnerable.
Why VOCs Are a Concern in New Construction
Newly constructed homes and commercial buildings often have higher VOC concentrations than older structures. This is due to the extensive use of synthetic materials and the fact that everything inside is new and actively off-gassing. Additionally, many new buildings are tightly sealed to reduce heating and cooling costs. Unfortunately, this also means that fresh air exchange is limited, trapping VOCs indoors.
Improving Indoor Air Quality in New Buildings
Reducing VOC exposure in new construction doesn’t require starting from scratch. With careful material selection and proactive air quality management, you can make any new building safer and healthier. Here are some key steps:
1. Choose Low-VOC or No-VOC Materials
When planning a build or renovation, opt for low-emission products. Many paints, adhesives, carpets, and composite woods are now available in low-VOC or zero-VOC versions. Look for certifications such as GREENGUARD or Green Seal when selecting materials.
2. Increase Ventilation During and After Construction
Proper ventilation helps dilute and remove VOCs from indoor air. Contractors should use mechanical ventilation and open windows when possible during and after the installation of high-emitting materials.
3. Allow Time for Off-Gassing
If feasible, wait several days to several weeks after construction is complete before occupying the building. This gives the most active off-gassing period time to pass.
4. Use Air Purification Systems
High-efficiency particulate air (HEPA) filters and activated carbon filters can help reduce VOC concentrations. Portable air purifiers or whole-building systems are effective options for both residential and commercial spaces.
5. Test Your Indoor Air Quality
Professional indoor air quality testing is the most reliable way to identify VOC levels and other pollutants. At Evergreen Air Quality Services, we offer comprehensive VOC testing to assess your space and recommend targeted solutions.
