In the field of sustainable construction, indoor air quality (IAQ) is more than just a health consideration—it’s a fundamental component of environmentally responsible building practices. The construction sector is crucial to environmental stewardship, accounting for nearly 40% of global carbon emissions and a substantial share of energy consumption. Prioritizing IAQ ensures occupants enjoy a healthier living or working environment while also aligning with the core principles of sustainable construction, which emphasize energy efficiency, resource conservation, and reduced environmental impact. Here are the five actionable ways to improve IAQ in sustainable construction projects.
What is IAQ?
Indoor air quality, or IAQ, refers to the level of air purity inside buildings, influenced by pollutants, humidity, and ventilation. High IAQ is essential in sustainable construction because it ensures clean, breathable air for occupants, free from harmful substances like volatile organic compounds (VOCs), dust, and mold spores. In sustainable construction, IAQ plays a crucial role in creating buildings that prioritize occupant well-being.
Poor IAQ has been linked to a wide range of health issues, from allergies and respiratory illnesses to cognitive impairment. In sustainable construction, efforts to improve IAQ not only support occupant health but also align with environmental goals, as reducing pollutants indoors often means reducing overall emissions and waste in construction materials and processes.
Sustainable construction integrates eco-friendly materials, energy-efficient ventilation systems, and design practices that reduce pollutant levels indoors.

5 Ways to Improve IAQ in Sustainable Construction Projects
Improving IAQ is essential in sustainable construction, as it ensures healthier, more comfortable living and working spaces while supporting eco-friendly building practices.
1. Select Low-Emitting and Non-Toxic Materials
The choice of building materials is one of the most significant factors impacting IAQ in sustainable construction. Many traditional materials release VOCs, formaldehyde, and other harmful chemicals, degrading IAQ and posing health risks to occupants.
- Why Low-Emitting Materials Matter: Low-emitting materials limit the release of VOCs and other toxic compounds, which are commonly found in paints, adhesives, and finishes. These substances can cause short-term symptoms like headaches, as well as long-term health issues, including respiratory problems and chemical sensitivities.
- Eco-Friendly Material Options: Sustainable construction promotes the use of materials that have low or zero VOC content. For instance:
- Low-VOC Paints and Coatings: These minimize the release of chemicals, creating healthier indoor environments.
- Formaldehyde-Free Plywood: This is ideal for cabinetry, shelving, and furniture in sustainable construction projects.
- Natural Fiber Insulation: Made from materials like wool or cotton, natural insulation provides effective temperature control without releasing pollutants.
2. Control Humidity and Prevent Mold Growth
Humidity control is essential for IAQ, as high humidity levels can lead to mold growth, which releases spores that reduce IAQ and trigger allergies and asthma. In sustainable construction, moisture management is an important part of the design and building process.
- What Does Humidity Control Do in IAQ: Excess humidity supports the growth of mold, mildew, and bacteria, all of which degrade air quality. Sustainable construction projects take measures to maintain optimal indoor humidity, usually between 30% and 50%, to prevent these issues.
