Cork

Cork stands out as a sustainable choice for eco-conscious builders. Harvested from the bark of cork oak trees, its extraction doesn't harm the tree, allowing it to continue growing and absorbing CO2. This process makes cork a renewable resource every nine to twelve years.

The material's strong insulating properties help block thermal transmission, keeping homes warm in winter and cool in summer. This reduces reliance on heating and cooling systems, reducing household carbon footprints.

Additionally, cork is inherently fire-resistant and hypoallergenic, making it an excellent choice for indoor environments. Builders appreciate cork's versatility. It can be used in flooring, wall coverings, underlayment, and insulation panels. Its acoustic properties help prevent noise pollution and its soft texture and resilience offer comfort.

Reclaimed/Recycled Wood

Reclaimed wood offers an environmentally responsible choice for construction. It's sourced from old buildings, barns, and other structures set for demolition, giving these materials a second life. Depending on where it’s sourced from, using reclaimed wood is a great way to add a touch of history and connection to the past without buying and owning a historic home. This practice prevents lumber from ending up in landfills and reduces the demand for new timber, minimizing deforestation.

Using reclaimed wood adds unique character and warmth to new buildings. Each piece carries distinct marks and patinas that can't be replicated in new wood, making it highly sought after for both aesthetic and historical value. It's also often more durable than new lumber, as the aging process eliminates weaker wood.

Moreover, reclaimed wood has a significantly lower carbon footprint compared to new wood production, which involves extensive logging, processing, and transportation. By reusing wood, builders cut down on energy consumption and carbon emissions.

Bamboo

Bamboo is a top choice for eco-friendly building materials, rapidly maturing in just 2–5 years. This quick growth cycle ensures a sustainable supply without the need for replanting, as bamboo regenerates from its own roots. Bamboo's lightweight yet strong nature makes it ideal for a variety of construction applications.

Its versatility extends to different architectural styles. It can bend to fit unique designs without compromising structural integrity. Builders and architects often utilize bamboo for flooring, wall panelling, and even scaffolding. Certain bamboo species are even known to be as strong as traditional hardwood.

The material's innate flexibility and strength aren't its only advantages. Bamboo also plays a crucial role in carbon sequestration, absorbing carbon dioxide at a higher rate than many trees, which further amplifies its eco-friendly profile.

Recycled Steel

Recycled steel’s ability to be recycled endlessly while maintaining its quality makes it a cornerstone in eco-friendly construction. In Lethbridge, Alberta—located roughly 200 km southeast of Calgary’s City Centre—the Reger Residence is a net-zero home built with recycled steel.

Builders and architects favour recycled steel for several reasons, including its durability and fire resistance. This material can withstand fires and severe weather conditions, including hurricanes and earthquakes.

Additionally, by repurposing steel from demolished buildings or unused materials, the construction industry can significantly decrease the volume of waste sent to landfills. This not only conserves landfill space but also reduces the energy and resources typically consumed in the production of new steel.

Recycled Plastic

Made from consumer waste, recycled plastic has become increasingly popular in construction due to its durability and versatility. It comes from materials such as water bottles and packaging, which might otherwise end up in landfills. By repurposing this waste, the building industry can significantly reduce its environmental footprint.

Recycled plastic is used in building applications like insulation panels, so you’ll likely come across it when choosing insulation for your home. It’s also commonly used in roofing tiles and piping. These eco-friendly materials are resistant to moisture and decay and require less energy to produce. They’re also lightweight, which cuts down on transportation costs and energy, and can be easily molded into a wide range of shapes and sizes.

Recycled Glass

Derived from old bottles and jars, recycled glass offers homeowners a sturdy, low-impact option. It is durable and available in various designs and colours as flooring and countertop material. It can also be integrated into tiles, facades, and even decorative elements.

Repurposing glass waste avoids the environmental toll associated with processing new materials. This lessens the volume of waste sent to landfills and cuts down on the need for virgin materials. Moreover, the energy required to melt down and reform glass is considerably less compared to producing new glass from scratch.

Hempcrete

Hempcrete offers a revolutionary approach to sustainable building. It combines hemp stalks, lime, and water to create a material that excels in eco-friendliness and functionality. This green technology for sustainable building is derived from one of the fastest-growing plants and incorporates the use of its by-products, making it a prime candidate for eco-conscious construction projects.

Hempcrete's insulation properties are notable; it maintains a balanced indoor temperature, reducing the need for heating and cooling systems. This feature considerably lowers energy consumption, making homes more efficient and environmentally friendly.

This material’s durability and resistance to decay enhance the longevity of buildings and decrease the need for repairs. Its lightweight nature also means that it places less strain on the foundation, allowing for simpler and more cost-effective construction. It’s also fire-resistant, providing an extra layer of safety to structures.

Precast Concrete

Precast concrete stands out for its efficiency and versatility, and prospective homeowners who value sustainability should add it to their home-building checklist. Factories produce precast concrete in a controlled environment, ensuring consistent quality and reducing on-site waste. It's transported to construction sites ready to install, which significantly cuts down project timelines and on-site environmental impacts.

Precast concrete is quite resilient and capable of withstanding extreme conditions like hurricanes or earthquakes. It also has excellent thermal mass, helping to regulate indoor temperatures and reduce reliance on heating and cooling systems. This helps lower energy consumption over the building's lifespan.
