Below, we've put together a list of 25 sustainable building materials that can help make your new home construction project both energy-efficient and environmentally friendly.
Proper insulation is one of the most important factors for high energy efficiency in homes. Sustainable insulation options will keep your home comfortable while minimizing environmental impact by using natural and recycled materials. Here are some excellent eco-friendly insulation choices.
Sheep’s wool insulation is a natural insulator known for its effectiveness and for being 100% natural. It's a great option because it compares to the benchmark set by other types of insulation.
Wool fibers trap air to provide excellent thermal insulation and help regulate humidity, which enhances indoor air quality.
Sheep’s wool is also fire-resistant and has a lower environmental impact compared to conventional insulation materials.
It's also worth pointing out that sheep’s wool insulation can be more expensive than other insulation options. The higher cost may be a drawback for homeowners on a budget. Wool insulation may also require treatment to prevent pests and ensure durability, which can add to your overall cost and long-term maintenance requirements.
Mycelium insulation panels come from fungal mycelium. These panels are fully compostable, and have excellent insulating properties.
Mycelium is resistant to pests and mold, and it grows very quickly. Builders can form it into various shapes, making it a versatile material for different sustainable construction projects.
That said, mycelium insulation panels are sensitive to moisture, which may compromise their insulating properties and durability over time. This is why they require careful installation and maintenance to ensure long-term effectiveness.
Plant-based polyurethane foam insulation comes from natural oils, such as soy or castor beans. This type of insulation offers high thermal resistance that helps reduce energy consumption and costs.
It's typically a spray that expands to fill gaps and cracks. This creates an effective barrier against heat loss and cold air infiltration.
Note that the production and installation of plant-based polyurethane foam insulation can release volatile organic compounds (VOCs). These may impact indoor air quality temporarily, but they dissipate over time.
While it is more sustainable than petroleum-based alternatives, the environmental benefits can vary depending on the sourcing and processing of the natural oils.
Recycled paper cellulose insulation is a material created with recycled newspaper. It's a great sustainable choice for insulating walls and attics.
This style of insulation usually receives treatment with non-toxic fire retardants for safety. It also insulates against sound almost as well as it insulates against heat.
It's also cost-effective and environmentally friendly since it repurposes waste paper that would otherwise end up in landfills.
Like any other building material, recycled paper cellulose insulation has its own drawbacks. The material can settle over time, which reduces its effectiveness and creates gaps where heat can escape.
It is also susceptible to moisture. Too much exposure can lead to mold growth and reduced insulating properties. This is why working with a professional like Dunn & Stone is important if you want to use this material in your construction project.
Structural materials form the backbone of any building. Choosing sustainable options can reduce the impact that building your home has on the environment. Here are some eco-friendly structural materials that promote green construction and sustainable building practices.
Reclaimed wood beams come from old buildings. Then they are repurposed for new construction projects. This reduces the need for new lumber to conserve natural resources and minimize waste.
Reclaimed wood provides a rustic, aesthetic appeal and is often more durable than newly harvested wood, so it's a surprisingly popular choice for anyone looking to build more sustainably.
Sourcing reclaimed wood can be labor-intensive and time-consuming, which can increase costs. There is also the potential for hidden problems to arise, such as pests, nails, or rot, that may require additional treatment or refinishing. This can also increase construction costs.
Hempcrete blocks are made from hemp fibers and lime and offer a sustainable alternative to traditional concrete.
Hempcrete provides excellent insulation, is lightweight, and has a very low carbon footprint. It's actually carbon negative, meaning it absorbs more carbon dioxide during its production than it emits.
Hempcrete blocks are ideal for non-load-bearing walls and infill in timber frame construction. The only drawback is that hempcrete has lower compressive strength compared to traditional concrete, making it unsuitable for certain structural load-bearing applications.
Adobe bricks are a traditional building material made from earth and organic materials like straw. They've been used for hundreds of years.
Adobe is known for its durability and natural insulation.
Making these bricks is sustainable because the process requires minimal energy. Adobe is particularly suited for dry climates and offers a natural, earthy aesthetic.
However, adobe bricks are not typically used in Texas-style homes, which often use other materials like brick, wood, and stucco instead.
Adobe bricks, like hempcrete, are ideal for non-load-bearing walls and infill in timber frame construction because of their excellent insulation. But they're also vulnerable to moisture, which can weaken the structure and lead to erosion over time. For this reason they're best-suited for regions with arid climates.
Fly ash concrete blocks are made of fly ash, a byproduct of coal combustion, mixed with concrete.
This innovative use of waste material helps reduce landfill waste and lowers the demand for traditional cement, which is energy-intensive to produce.
Fly ash concrete blocks are strong, durable, and contribute to sustainable building practices by repurposing industrial byproducts.
If you opt for fly ash concrete blocks, take into account that the quality of fly ash can vary. If you aren't using quality materials, can affect the consistency and performance of the blocks.
Fly ash concrete blocks are ideal for structural foundations and load-bearing walls, where their strength and durability can be put to full use.
Rammed earth walls are constructed by compacting soil into molds to create sturdy, energy-efficient walls. This ancient building technique uses natural resources and has a minimal carbon footprint.
Rammed earth provides excellent thermal mass to help regulate indoor temperatures and reduce energy consumption. They're great for use in dry climates and best suited for exterior walls.
SIP panels are made of a prefabricated insulating foam core that's sandwiched between two structural facings made of oriented strand board (OSB).
These panels provide superior insulation, strength, and energy efficiency.
SIPs are typically used for walls and roofs. They are an excellent choice for sustainable building projects aiming for high performance and low environmental impact.
Cross-laminated timber (CLT) panels are engineered wood panels made by layering timber in opposing directions.
CLT is a renewable material that offers high strength and stability.
Using CLT reduces reliance on traditional construction materials like steel and concrete, which have higher carbon footprints. CLT panels are also prefabricated, reducing construction waste and time on site.
The primary factor to keep in mind if you're investigating this material is the cost.
CLT can be more expensive than traditional wood framing materials because of the manufacturing process and the need for specialized labor during installation. CLT panels aren't easily available in all regions, which may also lead to higher shipping costs and longer construction times.
Choosing sustainable materials for roofing and exterior elements is another important consideration if your goal is to build an environmentally friendly home. The materials below enhance energy efficiency, manage rainwater, and reduce environmental impact without sacrificing the structural durability of other materials commonly used in exteriors.
Recycled steel roofing is made from repurposed steel. It offers excellent longevity and energy efficiency. It reflects heat to keep homes cooler in the summer. It's also fire-resistant and can withstand extreme weather conditions, making it a practical and sustainable choice for any new construction project.
Apart from the fact that it's more expensive than typical materials like asphalt shingles, recycled steel roofing can also be very noisy during heavy rain and storms. That said, it's great for home use, especially in areas prone to fires. It's even better for use in industrial construction projects where durability and low maintenance are top priorities.
Solar roof tiles are photo-sensitive tiles integrated directly into the roof to generate electricity from sunlight.
