Green Building Material/Product Selection Criteria
In sustainable construction, the choice of materials significantly impacts the overall environmental footprint. The key selection criteria for green building materials include:
- Resource Efficiency: This entails the use of materials that are recycled, sustainably sourced, or locally available. Products should prioritize recycled content and be manufactured through resource-efficient processes, reducing energy consumption and waste.
- Indoor Air Quality (IAQ): The materials should emit minimal harmful chemicals and have low volatile organic compounds (VOCs). This includes selecting non-toxic products and using low-VOC assembly methods to ensure a healthier indoor environment.
- Energy Efficiency: Materials should support the reduction of energy consumption in buildings, aiding in overall energy-efficient designs.
- Water Conservation: Selecting materials and systems that promote water-saving practices is vital in minimizing the consumption of this precious resource.
- Affordability: While aiming for sustainability, it remains crucial to balance costs such that the materials used are financially viable for the project.
These criteria collectively facilitate the construction of buildings that not only minimize environmental impacts but also enhance occupant health and promote sustainable environments.

Chapter Content
Resource Efficiency can be accomplished by utilizing materials that meet the following criteria:
- Recycled Content: Products with identifiable recycled content, including post-industrial content with a preference for post-consumer content.
- Natural, plentiful or renewable: Materials harvested from sustainably managed sources and preferably have an independent certification (e.g., certified wood) and are certified by an independent third party.
- Resource efficient manufacturing process: Products manufactured with resource-efficient processes including reducing energy consumption, minimizing waste (recycled, recyclable and or source reduced product packaging), and reducing greenhouse gases.
- Locally available: Building materials, components, and systems found locally or regionally saving energy and resources in transportation to the project site.
- Reusable or recyclable: Select materials that can be easily dismantled and reused or recycled at the end of their useful life.
- Recycled or recyclable product packaging: Products enclosed in recycled content or recyclable packaging.
- Durable: Materials that are longer lasting or are comparable to conventional products with long life expectancies.
Detailed Explanation
Resource efficiency in green building focuses on minimizing the environmental impact of materials used. This includes using products with recycled content, particularly post-consumer items, which help reduce waste. Additionally, sourcing materials that are natural, renewable, and certified ensures sustainability. Efficient production processes are crucial, aiming to lower energy use and greenhouse gas emissions. Locally sourced materials save on transportation emissions, while reusable and recyclable materials reduce waste at the end of their lifecycle. Durability is also a key factor, indicating that materials should last long to reduce the frequency of replacements.
Examples & Analogies
Imagine building a house using bricks made from recycled materials instead of new, which helps save the environment and reduces landfill waste. By also choosing local wood that comes from sustainably managed forests, the builder supports local businesses and minimizes transportation emissions. Just like bringing your reusable grocery bags to the store helps reduce plastic waste, selecting building materials thoughtfully contributes to a healthier planet.
2. Indoor Air Quality (IAQ)

Chapter Content
Indoor Air Quality (IAQ) is enhanced by utilizing materials that meet the following criteria:
- Low or non-toxic: Materials that emit few or no carcinogens, reproductive toxicants, or irritants as demonstrated by the manufacturer through appropriate testing.
- Minimal chemical emissions: Products that have minimal emissions of Volatile Organic Compounds (VOCs). Products that also maximize resource and energy efficiency while reducing chemical emissions.
- Low-VOC assembly: Materials installed with minimal VOC-producing compounds, or no-VOC mechanical attachment methods and minimal hazards.
- Moisture-resistant: Products and systems that resist moisture or inhibit the growth of biological contaminants in buildings.
- Healthfully maintained: Materials, components, and systems that require only simple, non-toxic, or low-VOC methods of cleaning.
- Systems or equipment: Products that promote healthy IAQ by identifying indoor air pollutants or enhancing the air quality.
Detailed Explanation
Enhancing indoor air quality (IAQ) is crucial for health and comfort in green buildings. Low or non-toxic materials minimize exposure to harmful chemicals and irritants. Limiting Volatile Organic Compounds (VOCs) in products helps prevent indoor pollution, promoting a healthier environment. Installation methods that use low-VOC compounds ensure that the air quality remains high. Moisture-resistant materials prevent mold growth, which can negatively impact health. The choice of cleaning materials is also essential; opting for non-toxic, low-VOC cleaning solutions contributes to better air quality. Overall, selecting materials that actively promote healthy air is vital for occupant well-being.
Examples & Analogies
Consider living in a home painted with low-VOC paint compared to a conventional one. In the low-VOC home, you would breathe easy, knowing there are fewer harmful chemicals lingering in the air. It’s like choosing to breathe fresh air in a forest rather than smog in a city; the quality of what surrounds you can make a significant difference to your health and comfort.
