Low VOC Materials

Low VOC Materials

Low VOC materials are an important consideration in sustainable building design because they can help improve indoor environmental quality while reducing the release of volatile organic compounds into occupied spaces. Volatile organic compounds, commonly known as VOCs, are carbon-based chemicals that can evaporate into the air from certain paints, adhesives, sealants, flooring products, furniture, coatings, and composite materials.

In a building, VOC emissions can occur during product application as well as after installation. Selecting products with low VOC emissions can therefore help reduce the concentration of potentially harmful pollutants indoors. The U.S. Environmental Protection Agency notes that indoor concentrations of some organic pollutants can be significantly higher than outdoor levels and that building materials and household products can be important sources of VOCs.

Why Low VOC Materials Matter

Low VOC materials contribute primarily to better indoor air quality. Conventional paints, adhesives, sealants, and coatings may release VOCs during curing and, in some cases, continue emitting them over time. Choosing products formulated to have lower emissions can help create healthier indoor environments for occupants.

They are particularly relevant in offices, schools, hospitals, hotels, residential buildings, and other spaces where people spend extended periods indoors. Reducing unnecessary chemical emissions can also support occupant comfort and reduce exposure to indoor air contaminants.

Common Low VOC Products

Low VOC options are available across many building-product categories, including:

• Interior paints and coatings
• Adhesives and sealants
• Carpet and resilient flooring
• Composite wood products
• Wall coverings
• Furniture and furnishings
• Insulation and other interior materials

When selecting products, project teams should not rely only on marketing terms such as “eco-friendly” or “green.” Product documentation, emissions testing, applicable standards, Low VOC Materials and recognised certifications should be reviewed to verify performance.

The U.S. EPA’s Indoor Air Quality resources provide information about indoor pollutants and strategies for improving indoor environmental conditions.

Low VOC Materials in Green Building

Low-emitting materials are commonly addressed within green-building programmes because material selection can directly influence indoor environmental quality. Depending on the applicable rating system and project category, requirements may address VOC content, emissions testing, product categories, or a combination of these factors.

For projects pursuing a specific green-building rating, the applicable criteria should be checked carefully because requirements can vary according to product type and rating-system version. Product manufacturers should be able to provide technical data sheets, safety documentation, emissions certificates, or test reports where required.

Conclusion

Low VOC materials are a practical strategy for creating healthier and more comfortable indoor environments. Their use can reduce emissions from common construction and interior products while supporting responsible material selection. However, low VOC content alone does not automatically mean that a product has zero health or environmental impact. A comprehensive approach should consider emissions, durability, material composition, installation requirements, maintenance, and the product’s overall environmental performance.

#BuildingMaterials

What Are Low VOC Materials and Why Are They Important in Green Building Design?

Low VOC materials are building and interior products formulated to release relatively low levels of volatile organic compounds (VOCs) into indoor air. VOCs are carbon-based chemicals that can evaporate at room temperature and may be released by products such as paints, coatings, adhesives, sealants, flooring, composite wood, furniture, and certain cleaning products. Because buildings can contain numerous sources of these emissions, material selection plays an important role in maintaining indoor environmental quality.

Low VOC materials are not necessarily completely free of VOCs. Instead, they are designed or manufactured to meet specified limits for VOC content or emissions, depending on the product category and applicable standard. Examples include low-emitting paints and coatings, adhesives, sealants, carpets, flooring systems, and composite wood products. Product manufacturers can provide technical documentation and emissions-testing information to demonstrate compliance with applicable requirements.

Why Are Low VOC Materials Important?

The primary importance of low VOC materials is their contribution to better indoor air quality. VOC concentrations indoors can be higher than outdoor concentrations because chemicals released from building materials, furnishings, consumer products, and other sources can accumulate when ventilation is insufficient. Some VOCs may cause irritation or other health effects, particularly when occupants are exposed to elevated concentrations for extended periods. The U.S. Environmental Protection Agency identifies building materials and furnishings among the potential sources of indoor VOCs and recommends strategies that include source control and adequate ventilation.

Using low-emitting materials helps reduce pollutant sources at the point of selection rather than relying only on mechanical ventilation to remove contaminants. This makes material selection an important part of an integrated indoor air-quality strategy.

Applications in Green Buildings

Low VOC materials can be incorporated throughout a building. Interior paints and coatings are common applications, but the strategy extends to flooring adhesives, sealants, wall coverings, carpets, furniture, composite wood, and other interior products.

In green-building projects, teams should evaluate products based on the specific requirements applicable to each product category. A product advertised as “low VOC” should not automatically be assumed to satisfy a green-building requirement. Depending on the rating system, compliance may depend on VOC content, emissions testing, recognised certification, or specific referenced standards.

For projects following green-building criteria, documentation should be collected during procurement. Technical data sheets, manufacturer declarations, emissions certificates, test reports, and product certifications can help demonstrate that specified materials meet the required criteria.

Benefits Beyond Indoor Air Quality

Low VOC material selection can also support a healthier construction and occupancy process. Lower-emitting products can reduce chemical odours and pollutant emissions during installation and after occupancy. When combined with appropriate ventilation, source control, moisture management, and good construction practices, they can contribute to a more comfortable indoor environment.

However, VOC performance should be considered alongside other material characteristics, including durability, maintenance requirements, chemical composition, recycled content where relevant, responsible sourcing, and overall environmental impact.

Conclusion

Low VOC materials are an important component of green building design because they help reduce emissions from common construction and interior products and support healthier indoor environments. Their effective use requires more than simply selecting products labelled “low VOC.” Design and procurement teams should verify product-specific requirements, obtain appropriate documentation, and consider material emissions as part of a broader indoor environmental quality strategy.

#GreenBuildingDesign

What Types of Building Products Commonly Contain Volatile Organic Compounds (VOCs)?

Volatile organic compounds (VOCs) are chemicals that can evaporate into the air under normal indoor conditions. They are found in a wide range of construction, finishing, furnishing, and maintenance products. In building projects, VOC emissions can originate from products used during construction as well as materials that continue to release chemicals after installation. Identifying these sources early helps architects, designers, contractors, and facility managers make better material selections and support healthier indoor environments.

1. Paints, Coatings, and Finishes

Paints, primers, varnishes, stains, and protective coatings are among the most familiar sources of VOCs. These products may contain solvents that evaporate during application and curing. Interior paints and coatings with reduced VOC content or verified low emissions can help minimise indoor pollutant sources.

2. Adhesives and Sealants

Adhesives are widely used for flooring, wall coverings, insulation, laminates, and other applications. Sealants are commonly used around joints, windows, doors, sanitary fixtures, and building-envelope components. Depending on their chemical formulation, these products can release VOCs during and after installation.

The U.S. Environmental Protection Agency identifies paints, solvents, adhesives, and similar products as potential indoor sources of VOCs. It also recommends source-control measures as an important strategy for improving indoor air quality.

3. Flooring Products

Flooring systems can contain VOC-emitting components at several levels. These may include vinyl flooring, carpets, synthetic flooring, wood finishes, floor adhesives, and protective coatings. In some cases, the adhesive used to install a flooring product can be a significant source of emissions.

Selecting low-emitting flooring systems should therefore involve evaluating both the flooring material and associated installation products.

4. Composite Wood and Engineered Wood

Products such as particleboard, medium-density fibreboard, plywood, cabinetry, shelving, and other composite wood materials may contain adhesives or resins that release formaldehyde and other chemicals. Formaldehyde is an important indoor air pollutant associated with certain pressed-wood products.

Selecting products with lower formaldehyde emissions or products certified to recognised emissions standards can help reduce indoor pollutant levels.

5. Wall Coverings and Interior Finishes

Wall coverings, laminates, decorative panels, wallpapers, and certain surface treatments can contain adhesives, coatings, or other chemical components that contribute to indoor emissions. The complete installation system should therefore be considered rather than evaluating only the visible finish.

6. Insulation and Other Construction Materials

Certain insulation products, sealants, foams, and specialty construction materials can contain chemical components that may contribute to VOC emissions. The actual emission profile varies significantly according to product formulation, installation method, curing conditions, and manufacturer.

7. Furniture and Furnishings

VOC sources are not limited to permanent building materials. Office furniture, cabinets, desks, upholstered products, mattresses, and other furnishings can release VOCs from composite wood, adhesives, coatings, fabrics, and finishes.

This is particularly relevant in offices, hotels, schools, healthcare facilities, and residential projects where large quantities of furniture may be introduced at the same time.

8. Cleaning and Maintenance Products

Although they are not normally considered construction materials, cleaning agents, disinfectants, polishes, air fresheners, and other maintenance products can contribute to indoor VOC levels. A comprehensive indoor-air-quality strategy should therefore address both building materials and operational products.

Choosing Lower-Emitting Products

When specifying materials, project teams should look beyond the term “low VOC.” VOC content and VOC emissions are not necessarily the same measurement. A product can have relatively low VOC content but still require evaluation for its actual indoor emissions.

For green-building projects, manufacturers should provide relevant technical documentation, emissions-testing reports, certifications, or declarations as required by the applicable rating system. Material selection should also consider durability, maintenance, chemical composition, and overall environmental performance.

Conclusion

Common VOC sources in buildings include paints, coatings, adhesives, sealants, flooring, composite wood, wall coverings, insulation products, furniture, and cleaning materials. Identifying these sources early allows project teams to select lower-emitting alternatives and create a healthier indoor environment.

#SustainableConstruction

How Do Low VOC Materials Improve Indoor Air Quality and Occupant Health?

Low VOC materials can improve indoor environmental quality by reducing the amount of volatile organic compounds released into occupied spaces from building products and interior finishes. VOCs are chemicals that can evaporate into indoor air from sources such as paints, coatings, adhesives, sealants, flooring, composite wood, furniture, and other products. Because people can spend a significant amount of time inside buildings, controlling pollutant sources is an important part of healthy building design.

Reducing Indoor Pollutant Sources

The most direct benefit of low VOC materials is source control. Instead of relying exclusively on ventilation systems to remove pollutants after they have entered the indoor environment, designers can reduce the quantity of pollutants released in the first place.

The U.S. Environmental Protection Agency identifies building materials, furnishings, paints, solvents, adhesives, and other products as potential sources of indoor VOCs. Some VOC exposure can cause short-term symptoms such as eye, nose, and throat irritation, headaches, nausea, and dizziness, although health effects vary according to the specific chemical, concentration, and duration of exposure.

Selecting lower-emitting products can therefore help reduce one category of indoor air contaminants.

Supporting Better Indoor Air Quality

Indoor air quality depends on several factors, including pollutant sources, ventilation, filtration, humidity, moisture control, cleaning practices, and occupant activities. Low VOC materials address the source component of this equation.

When lower-emitting paints, adhesives, flooring, sealants, furniture, and composite wood products are used together, the overall chemical load introduced into an interior can be reduced. This is particularly valuable in tightly sealed, energy-efficient buildings where ventilation must be carefully designed to maintain healthy indoor conditions.

However, low VOC materials should not be considered a replacement for adequate ventilation. The EPA recommends a combination of source control, ventilation, and air cleaning as important approaches to improving indoor air quality.

Supporting Occupant Comfort and Health

Newly constructed or renovated spaces can sometimes experience noticeable chemical odours because of emissions from recently installed materials. Selecting low-emitting products can help reduce these emissions and may contribute to a more comfortable environment during occupancy.

This can be particularly important in schools, hospitals, offices, hotels, residential buildings, and other frequently occupied spaces. Children, older adults, and people with certain sensitivities may be more vulnerable to poor indoor air conditions, making pollutant-source reduction an important consideration.

Importance of Product Verification

It is important to understand that “low VOC” does not necessarily mean “zero VOC” or guarantee that a product has no health impact. Different products can contain different chemicals, and VOC content is not always an indicator of actual indoor emissions.

For green-building projects, specifications should therefore identify appropriate limits and verification methods. Depending on the applicable criteria, project teams may need manufacturer declarations, laboratory emissions-testing reports, recognised certifications, or other documentation.

A Holistic Indoor Air Quality Strategy

Low VOC material selection works best when combined with other indoor environmental strategies. These include adequate outdoor-air ventilation, effective filtration, moisture control, proper construction sequencing, protection of materials from contamination, and appropriate cleaning procedures before occupancy.

The U.S. EPA Indoor Air Quality programme provides further guidance on indoor pollutants, source control, ventilation, and other strategies for maintaining healthier indoor environments. The EPA’s VOC resources also provide additional information about VOCs and their potential impact on indoor air quality.

Conclusion

Low VOC materials improve indoor air quality primarily by reducing the amount of chemical pollutants released from building products and furnishings. This source-control approach can support occupant comfort and reduce exposure to certain indoor pollutants. However, the best results come from combining low-emitting materials with effective ventilation, moisture management, filtration, and responsible building operation.

#EcoFriendlyConstruction

What Criteria or Certifications Should Be Considered When Selecting Low VOC Materials?

Selecting low VOC materials for a green building requires more than choosing products labelled “low VOC” or “zero VOC.” A professional material-selection process should evaluate VOC content, actual emissions, testing methods, third-party certification, product category requirements, and supporting documentation. This is important because VOC content and indoor emissions are not identical measures, and a product with a low VOC label may still contain chemicals relevant to indoor air quality. The U.S. Environmental Protection Agency specifically cautions that “low VOC” and “no VOC” labels do not automatically demonstrate that a product is safer from an indoor-air-quality perspective.

1. Check VOC Content

For products such as paints, coatings, adhesives, and sealants, the first consideration is the product’s VOC content, usually expressed in grams per litre (g/L). The applicable limit depends on the product category and the relevant standard or regulation. Project specifications should clearly identify the maximum permitted VOC content rather than relying on general manufacturer claims.

2. Prefer Emissions-Based Testing

For indoor environmental quality, actual emissions can be more meaningful than VOC content alone. Emissions testing evaluates chemicals released by a product into indoor air under controlled laboratory conditions. The California Department of Public Health (CDPH) Standard Method v1.2-2017 is one widely referenced emissions-testing method for building products. EPA’s Indoor AirPlus programme uses this method for several categories of low-emission building materials.

3. Look for Recognised Third-Party Certifications

Third-party certifications can make product verification easier because an independent organisation evaluates products against defined criteria. Examples referenced by EPA include GREENGUARD, SCS Indoor Advantage Gold, Intertek Clean Air Gold, MAS Certified Green, and CRI Green Label Plus, depending on the product category and applicable requirements.

The certification should be checked carefully to determine exactly what it covers. A certification may address emissions but not VOC content, or it may apply only to a specific product category.

4. Evaluate Formaldehyde and Other Relevant Chemicals

A comprehensive assessment should not focus exclusively on total VOCs. Certain individual chemicals can be important from an indoor-health perspective, and EPA notes that reducing total VOCs does not necessarily guarantee a safer product because different VOCs can have substantially different toxicity profiles.

This is particularly relevant for composite wood, cabinetry, flooring, adhesives, and interior finishes.

5. Verify Product Documentation

Before approval, project teams should request technical data sheets, safety data sheets, emissions-test reports, certification documents, manufacturer declarations, and product-specific compliance statements. The documentation should identify the exact product, manufacturer, formulation or product series, testing standard, certification status, and validity period where applicable.

6. Consider Performance and Durability

Low VOC performance should not be evaluated in isolation. The product should also meet requirements for durability, moisture resistance, cleaning, maintenance, installation, and expected service life. EPA guidance recommends considering installation and maintenance requirements as well as how materials perform throughout their service life.

Conclusion

The key criteria for selecting low VOC materials are verified VOC content, emissions performance, recognised third-party certification, chemical transparency, product-specific compliance, documentation, and durability. Most importantly, project teams should distinguish between a marketing claim and independently verified performance.

For green-building projects, the applicable rating-system requirements should be reviewed before material approval because accepted standards and documentation requirements can vary by product category and rating-system version. The EPA Indoor AirPlus building-material guidance provides a useful reference for identifying low-emission products and understanding emissions-based criteria.

#HealthyBuildings

What Are the Environmental, Health, and Sustainability Benefits of Using Low VOC Materials?

Low VOC materials are increasingly used in green building design because they can help reduce indoor pollutant sources while supporting healthier and more sustainable buildings. These materials are commonly used for paints, coatings, adhesives, sealants, flooring, composite wood, carpets, furniture, and other interior products. Their main advantage is the reduction of certain chemical emissions into indoor spaces, although VOC performance should always be evaluated alongside ventilation, product composition, durability, and other environmental factors.

1. Health Benefits

The most important benefit of low VOC materials is their potential contribution to better indoor air quality. Building materials and furnishings can release VOCs into indoor air, and concentrations of some VOCs can be significantly higher indoors than outdoors. Depending on the specific chemical and level and duration of exposure, VOCs may contribute to symptoms such as eye, nose, and throat irritation, headaches, dizziness, nausea, and respiratory discomfort. Some individual VOCs are also associated with more serious long-term health concerns.

Using lower-emitting paints, adhesives, flooring, furniture, and composite wood products can reduce one important source of indoor pollution. This can be particularly valuable in offices, schools, hospitals, hotels, residential buildings, and other spaces where occupants spend substantial amounts of time.

However, low VOC materials should not be viewed as a complete indoor-air-quality solution. The U.S. Environmental Protection Agency recommends combining source control with adequate ventilation, filtration, and air cleaning where appropriate.

2. Environmental Benefits

Reducing VOC emissions can also support broader environmental objectives. VOCs are relevant to outdoor air pollution because many reactive VOCs can participate in atmospheric reactions that contribute to ground-level ozone and smog. Using lower-emitting products can therefore form part of a broader pollution-prevention strategy.

However, environmental performance should not be judged solely by VOC content. A product with a “low VOC” label is not automatically environmentally preferable in every respect. Product teams should also consider manufacturing impacts, resource use, durability, recyclability, chemical composition, packaging, and transportation.

3. Sustainability Benefits

Low-emission material selection supports the concept of source reduction, which is an important principle of sustainable building design. Instead of depending entirely on ventilation systems to remove pollutants after they enter the building, designers can reduce pollutant sources through material selection.

This approach can complement energy-efficient building design. As buildings become more airtight to improve energy performance, controlling indoor pollutant sources becomes increasingly important because pollutants can accumulate when ventilation is inadequate. EPA guidance highlights the relationship between energy-efficient building envelopes, ventilation, and indoor pollutant control.

Low-emitting materials can also contribute to green-building objectives related to indoor environmental quality. Programs such as EPA Indoor AirPlus incorporate low-emission materials as part of a broader strategy for healthier homes.

4. Improved Occupant Comfort

Lower-emitting materials can help reduce chemical odours associated with newly constructed or renovated spaces. This can improve the perceived comfort of occupants during the transition into a newly completed building. Proper ventilation during installation and before occupancy remains important because even lower-emitting products may release chemicals during curing or installation.

5. Better Material Selection Practices

The use of low VOC materials can encourage project teams to adopt more rigorous material-selection procedures. Instead of relying only on marketing claims, designers and contractors can request emissions-testing reports, product certifications, technical data sheets, and manufacturer declarations.

It is also important to distinguish VOC content from VOC emissions. EPA notes that “low VOC” or “no VOC” labels do not necessarily guarantee that a product is free from chemicals that may be relevant to indoor health. The toxicity of individual chemicals can vary considerably, so a lower total VOC value does not automatically mean that one product is healthier than another.

Conclusion

The key benefits of low VOC materials can be summarised across three areas: health, environmental performance, and sustainability. They can help reduce indoor pollutant sources, support better indoor air quality, improve occupant comfort, contribute to pollution-prevention objectives, and strengthen green-building material-selection practices.

For the best results, low VOC materials should be combined with adequate ventilation, moisture management, filtration, responsible construction practices, and appropriate product verification. Project teams should also evaluate durability, chemical composition, lifecycle impacts, and applicable certification requirements rather than selecting products solely because they carry a “low VOC” label.

#SustainableMaterials

Case Study of Low VOC Materials

A useful case study demonstrating the practical application of low VOC materials is the 40 Concord Avenue Renovation at Harvard University’s Radcliffe Institute for Advanced Study in Cambridge, Massachusetts. The project involved a comprehensive renovation of a small office building within the Bunting Quadrangle. Sustainability was incorporated into the renovation through energy efficiency, water conservation, lighting controls, and careful selection of interior materials. Most importantly for indoor environmental quality, 100% of the project’s adhesives, sealants, paints, coatings, and composite wood products were specified as low-emitting materials.

Project Approach

The project demonstrates an important principle of sustainable material selection: indoor air quality should be considered during the design and procurement stages rather than after construction is completed. Paints, adhesives, sealants, coatings, and composite wood can all contribute to chemical emissions indoors. By specifying low-emitting alternatives across these product categories, the project reduced potential sources of indoor pollutants.

The strategy was implemented as part of a broader sustainability programme rather than as an isolated material decision. The renovation also achieved a 43% reduction in water use compared with the applicable baseline, reduced lighting power density by 45%, and used occupancy controls for a large proportion of its connected lighting load.

Material Selection

The case study is particularly relevant because it demonstrates the importance of addressing multiple material categories. Low-emission performance was not limited to wall paint. Adhesives, sealants, coatings, and composite wood were also considered.

This comprehensive approach is useful because a building can still have significant indoor pollutant sources if only one material category is replaced. For example, selecting low VOC paint while using high-emitting adhesives or composite wood products may leave other sources of emissions uncontrolled.

Evidence From Residential Research

A separate peer-reviewed case study, The Development of Low Volatile Organic Compound Emission House, investigated a newly constructed residential building in which construction materials were tested before use. Researchers selected low-VOC-emission materials and combined material selection with increased ventilation. The study reported total VOC concentrations ranging from non-detectable to 43 μg/m³, substantially below the published concentrations cited for new houses in the study.

This research demonstrates an important principle: material selection and ventilation work together. Reducing pollutant sources through low-emitting materials can be complemented by adequate ventilation to manage emissions that cannot be eliminated completely.

Key Lessons for Green Building Projects

Several practical lessons can be drawn from these examples:

• Identify potential VOC sources during the design stage.
• Specify low-emitting paints, coatings, adhesives, and sealants.
• Evaluate composite wood and other interior products separately.
• Request product-specific technical documentation and emissions information.
• Consider VOC emissions alongside ventilation and indoor air-quality design.
• Maintain procurement records to demonstrate material compliance.
• Avoid relying solely on general “eco-friendly” or “low VOC” marketing claims.

The Harvard case demonstrates that low-emitting materials can be incorporated into a broader building sustainability strategy, while the residential research shows the measurable indoor-air-quality value of combining low-emission materials with appropriate ventilation.

Conclusion

The application of low VOC materials is not limited to individual products such as paints. A successful strategy considers the entire interior material system, including coatings, adhesives, sealants, flooring-related products, composite wood, and furnishings where applicable. The 40 Concord Avenue renovation provides a practical example of comprehensive low-emitting material selection in an office renovation, while the residential research demonstrates how material selection combined with ventilation can reduce indoor VOC exposure.

#GreenBuilding

White Paper on Low VOC Materials

Executive Summary

Low VOC materials are an important component of healthy and sustainable building design. Volatile organic compounds (VOCs) are carbon-containing chemicals that can evaporate from solids and liquids and enter indoor air. They can be released by paints, coatings, adhesives, sealants, flooring, composite wood, furnishings, and numerous other products. The U.S. Environmental Protection Agency notes that concentrations of many VOCs can be substantially higher indoors than outdoors and that some VOCs may have short- and long-term health effects.

Low VOC material strategies aim to reduce pollutant emissions at their source. Instead of depending entirely on ventilation to remove contaminants after they enter a building, designers can reduce the quantity of emissions generated by selecting appropriately tested and certified products. This approach can support indoor air quality, occupant comfort, and broader green-building objectives.

However, “low VOC” should not be treated as a universal guarantee of safety. EPA explains that labels such as “low VOC” or “no VOC” do not necessarily mean a product is free from potentially harmful volatile chemicals. The toxicity of individual compounds can also vary significantly.

1. Introduction

Modern buildings contain numerous materials and products that can influence indoor air quality. Paints, adhesives, sealants, flooring systems, cabinetry, composite wood, furniture, and coatings may release chemical compounds during installation and occupancy.

As buildings become increasingly energy efficient and airtight, controlling indoor pollutant sources becomes an important part of building design. Low-emission material selection can therefore complement ventilation, filtration, moisture control, and other indoor environmental quality strategies.

The objective is not simply to eliminate every VOC from a building, which is generally impractical, but to identify significant sources and select products with verified lower emissions where appropriate.

2. Understanding VOCs

VOCs are a broad group of organic chemicals with sufficient volatility to enter the air. They include many different substances with different chemical and health characteristics. EPA’s technical guidance explains that VOCs are commonly classified according to volatility and includes substances such as formaldehyde, toluene, acetone, ethanol, and other compounds within the broader group.

Potential VOC sources in buildings include:

• Paints and coatings
• Adhesives and sealants
• Carpets and flooring systems
• Composite wood and cabinetry
• Wall coverings
• Insulation and construction products
• Furniture and furnishings
• Cleaning and maintenance products

EPA identifies building materials and furnishings among potential sources of indoor VOC emissions.

3. Importance of Low VOC Materials

The primary objective of low VOC material selection is source control. By choosing lower-emitting products, project teams can reduce the amount of chemical pollution introduced into indoor spaces.

This is particularly relevant to buildings such as offices, schools, hospitals, hotels, residential developments, and educational facilities where occupants may spend many hours indoors.

Lower-emitting materials can also help reduce chemical odours associated with newly constructed or renovated spaces. However, material selection should always be combined with adequate ventilation because low-emission products do not eliminate the need for effective indoor-air management.

4. VOC Content Versus VOC Emissions

One of the most important considerations in material selection is the distinction between VOC content and VOC emissions.

VOC content refers to the quantity of volatile compounds contained within a product, while emissions testing evaluates chemicals released from the product into the surrounding air under specified conditions. These measurements are related but are not interchangeable.

EPA specifically warns that reducing total VOC levels does not necessarily guarantee that a product is safer because individual VOCs can differ substantially in toxicity.

For this reason, professional specifications should consider both applicable content limits and emissions performance.

5. Testing and Certification

Independent testing and certification can provide stronger evidence than general marketing claims.

The California Department of Public Health (CDPH) Standard Method v1.2-2017 is a recognised method for testing VOC emissions from indoor sources using environmental chambers. CDPH states that its standard method has been referenced by various building standards, codes, and green-building rating systems.

Depending on the product category and project requirements, recognised certification programmes can also help verify low-emission performance. EPA’s Indoor AirPlus resources provide guidance for identifying compliant low-emission building materials and reference emissions-based requirements.

Project teams should verify the exact scope of any certification because a certification may apply only to a particular product category, formulation, or emissions criterion.

6. Material Selection Strategy

A successful low VOC strategy should begin during the design stage. Architects, interior designers, sustainability consultants, contractors, and procurement teams should establish material requirements before products are purchased.

A practical process includes:

1. Identify products likely to contribute to indoor emissions.
2. Establish VOC-content or emissions requirements for each category.
3. Specify recognised testing or certification methods.
4. Request manufacturer documentation before approval.
5. Review technical data and certification validity.
6. Maintain procurement records throughout construction.
7. Verify installed products against approved specifications.

This process reduces the risk of substitutions that do not meet the project’s indoor-air-quality objectives.

7. Health and Indoor Environmental Quality

Indoor exposure to VOCs varies according to the chemical, concentration, duration of exposure, ventilation, and other environmental factors. Some VOCs can cause irritation, headaches, dizziness, or other adverse effects, while certain individual compounds present more serious health concerns.

The goal of low-emission material selection is therefore to reduce unnecessary pollutant sources. EPA identifies source control as an important strategy for managing indoor air quality and recommends combining source reduction with ventilation and other appropriate measures.

Low VOC materials are especially valuable as part of a broader strategy that includes:

• Adequate outdoor-air ventilation
• Effective filtration
• Moisture control
• Proper construction sequencing
• Protection of materials from contamination
• Appropriate cleaning practices
• Post-construction ventilation or flush-out where applicable

8. Environmental and Sustainability Considerations

Low VOC performance is only one aspect of sustainable material selection. A product should not automatically be considered environmentally superior simply because it has low VOC content.

A comprehensive assessment can also consider:

• Product durability
• Resource consumption
• Recycled or renewable content
• Responsible sourcing
• Manufacturing impacts
• Packaging
• Transportation
• Maintenance requirements
• End-of-life options
• Chemical transparency

This broader perspective prevents the project from optimising one environmental attribute while overlooking other significant impacts.

9. Application in Green Building Projects

Low VOC materials can be incorporated into almost every stage of interior construction. Paints and coatings are common applications, but project teams should also consider adhesives, sealants, flooring, carpets, composite wood, furniture, and other interior products.

The exact compliance pathway depends on the green-building rating system, project type, product category, and applicable version of the requirements. Therefore, teams should not assume that a product labelled “low VOC” automatically qualifies.

The EPA’s current Indoor AirPlus documentation provides an example of a structured approach to identifying low-emission building materials and verifying compliance through recognised criteria and documentation.

10. Implementation Challenges

One common challenge is inconsistent terminology. Manufacturers may use terms such as “eco-friendly,” “green,” “zero VOC,” or “low VOC” without providing sufficient information to compare products objectively.

Another challenge is substitution during construction. A specified product may become unavailable or be replaced by a locally available alternative. Any substitution should therefore be reviewed against the original VOC-content and emissions requirements before approval.

Cost, availability, durability, colour selection, installation performance, and contractor familiarity can also influence product selection. These issues are best addressed during design and procurement rather than after construction begins.

11. Recommended Best Practices

For effective implementation, project teams should:

• Develop a low-emission material specification early.
• Identify product categories requiring compliance.
• Prioritise independently verified emissions data.
• Request current manufacturer documentation.
• Distinguish VOC content from emissions performance.
• Consider individual chemicals rather than relying only on total VOC values.
• Review proposed substitutions before installation.
• Coordinate material selection with ventilation and indoor-air-quality planning.
• Maintain a material compliance register throughout construction.
• Verify final installed products against approved documentation.

Conclusion

Low VOC materials provide a practical way to reduce indoor pollutant sources and support healthier building environments. Their value is greatest when they are integrated into a comprehensive indoor environmental quality strategy rather than treated as an isolated product-selection exercise.

The most important principle is verified performance rather than marketing terminology. A professional low VOC strategy should consider product-specific requirements, emissions testing, recognised certification, chemical composition, documentation, durability, and overall environmental performance.

#IndoorAirQuality

Industry Application of Low VOC Materials

Low VOC materials have become an important part of sustainable construction across commercial, residential, healthcare, education, hospitality, industrial, and institutional sectors. Their primary application is to reduce the release of volatile organic compounds from building materials and interior products, supporting better indoor environmental quality. VOCs can originate from paints, adhesives, sealants, flooring, composite wood, insulation, furnishings, and other products used throughout a building. The U.S. Environmental Protection Agency notes that concentrations of many VOCs can be substantially higher indoors than outdoors, making source control an important consideration in building design.

1. Commercial Buildings

Offices and commercial spaces use significant quantities of paints, carpets, flooring adhesives, sealants, furniture, partitions, and composite wood products. Low VOC alternatives can be specified for these applications to reduce indoor pollutant sources.

Material specifications can require low-emission paints, coatings, adhesives, flooring systems, and furniture. This approach is particularly useful in open-plan offices where large numbers of occupants spend extended periods indoors.

2. Healthcare Facilities

Hospitals and healthcare facilities require careful control of indoor environmental conditions because patients, visitors, and healthcare workers may spend considerable time inside the building.

Low-emission flooring, adhesives, wall finishes, coatings, cabinetry, and furniture can form part of an indoor-air-quality strategy. Material selection should also consider durability, cleanability, infection-control requirements, and chemical compatibility.

3. Schools and Educational Buildings

Schools are another important application because classrooms can experience high occupant density and extended periods of occupancy. Low-emitting paints, flooring, adhesives, composite wood, and furnishings can help reduce unnecessary sources of chemical emissions.

The approach should be combined with adequate ventilation and moisture management. EPA identifies source control and ventilation as key strategies for maintaining healthier indoor air.

4. Residential Construction

Low VOC materials are increasingly used in homes and apartments, particularly for interior paints, carpets, flooring, cabinetry, adhesives, and manufactured wood products.

EPA’s Indoor AirPlus programme specifically incorporates low-emission materials, including low-VOC paints and carpets and low-formaldehyde manufactured wood products, as part of its indoor environmental quality approach.

5. Hospitality and Hotels

Hotels can use low-emission materials across guestrooms, corridors, restaurants, conference rooms, and common areas. Paints, wall coverings, flooring, furniture, sealants, and cabinetry are important material categories.

Because hotel interiors are frequently renovated and occupied continuously, selecting lower-emitting products can help manage pollutant sources during both construction and operation.

6. Industrial and Manufacturing Facilities

Industrial buildings can apply low VOC materials to offices, employee areas, laboratories, workshops, coatings, and architectural finishes. Certain industrial coating applications also use waterborne, UV-cured, high-solids, and powder coatings as lower-emitting alternatives, depending on performance requirements.

7. Institutional and Government Buildings

Government offices, universities, research facilities, and public buildings can incorporate low VOC requirements directly into construction specifications and procurement policies.

For example, EPA’s own sustainable-design specifications include low-VOC requirements for products such as adhesives, sealants, paints, flooring adhesives, and other construction materials.

8. Interior Fit-Out and Renovation

Low VOC materials are particularly valuable during renovation because activities such as painting, flooring installation, sealing, and cabinetry installation can temporarily increase indoor chemical emissions. EPA specifically identifies paints, varnishes, sealants, and adhesives as common VOC sources during remodeling.

Where possible, renovation projects should schedule high-emission activities when occupants are absent, provide appropriate ventilation, and select verified low-emission alternatives.

9. Material Verification and Certification

Professional application requires more than relying on labels such as “eco-friendly” or “low VOC.” Project teams should review product-specific documentation and, where applicable, third-party emissions certifications.

The California Department of Public Health Standard Method v1.2-2017 is an established method for evaluating VOC emissions from indoor sources using environmental chambers and has been referenced by multiple building standards and green-building programmes.

EPA’s Indoor AirPlus guidance similarly emphasises emission-based evaluation and warns against relying on vague environmental claims.

Conclusion

The industry application of low VOC materials extends across commercial offices, healthcare facilities, schools, residences, hotels, industrial buildings, government facilities, and renovation projects. The strategy is most effective when incorporated into specifications from the early design stage and supported by product verification, appropriate installation practices, ventilation, and moisture control.

Low VOC materials should not be considered a standalone solution for indoor air quality. EPA recommends a broader approach involving source control, ventilation, filtration, and air cleaning where appropriate.

For green-building projects, the applicable rating-system requirements should be reviewed before material approval, since acceptable VOC limits, emissions-testing methods, certifications, and documentation requirements can vary by product category and rating-system version.
