The built environment’s impact on climate change is palpable. Manufactured buildings account for the majority of greenhouse gas emissions and are responsible for about 37 per cent of energy consumption, globally. While much of that negative impact comes from operational building use, embodied carbon — that which is created by design and production — also contributes to these overwhelming emissions.
In particular, construction’s impact on the environment involves the use of unsustainable materials like steel and aluminium. Learn how the industry can mitigate these negative effects and work toward a brighter future for building.
Benefits of Eco-Friendly Construction Alternatives
Environmentally friendly building materials offer alternatives to energy-wasting manufacturing and high-maintenance installs. By choosing these innovative products, you lower the carbon footprint of your construction projects, contributing to global climate goals. Using sustainable materials and efficient processes helps reduce natural resource extraction and waste.
Sustainable building materials not only offer environmental benefits but also financial incentives. Architects and contractors should understand sustainable design to meet the evolving demands of consumers. Getting creative with the materials you use for a construction project can make your work more desirable to clients and save building costs. Eco-friendly materials are often repurposed and cheaper than traditional building materials.
Further, the buildings will be energy-efficient and weatherproof, saving money on upkeep and insurance. Climate-related, extreme weather events are becoming more prevalent, and strata insurance costs are rising. Building insurance costs can potentially be decreased with the use of sustainable, strong materials. The resilience and flexibility of these alternatives also allow your construction projects to adapt to changing needs, reducing renovation costs down the line. There are often green energy tax incentives for businesses participating in eco-friendly practices, as well.
Practical Applications of Sustainable Building Materials
Sustainable construction materials are in the process of being catalogued for their exact impacts on the environment, including embodied energy consumption, water waste, and emissions. This allows you to calculate the exact savings per project from using one material over the other.
For instance, you can calculate the embodied impacts of traditional concrete versus the more sustainable fly ash concrete. Taking control of your material sourcing, production, and utilization will allow you to contribute positively to climate action with transparency and ongoing plans for improvement.
Avoidance of Unnecessary Sourcing
Properly planned construction projects should have detailed breakdowns of material needs. This prevents overestimations and excess resource tapping. Strive to work with suppliers that source locally and responsibly, embracing sustainable practices. This not only cuts down on resource overuse but also decreases shipping transportation emissions and supports the local economy. Putting your foot down when it comes to sustainable sourcing can prompt other suppliers to follow suit.
Designing for longevity can also mitigate the need for frequent renovations or maintenance. This reduces the amount of materials that need to be sourced down the line. While most construction companies and builders don’t manufacture their project materials, it’s important to know where these materials come from and exactly how much you need for each project. If there is any wasted material, make sure to reserve it for your next build rather than dispose of it.
Using Regenerative Building Materials
Tapping into the circular design process is key here. Leftover materials from past projects, whether those are your projects or others, can be upcycled. Items can be repurposed or recycled to create something new.
Look for regenerative materials — materials that actively contribute to environmental health. For instance, incorporating reclaimed wood from sustainably managed forests can reduce the demand for timber and simultaneously promote the restoration of ecosystems and biodiversity.
Always look for alternatives to concrete, steel, and other traditional building materials. Some examples include:
- Ashcrete;
- Green concrete;
- Hempcrete;
- Cross-laminated timber;
- Bamboo;
- Salvaged materials;
Eco-innovations in construction are being developed rapidly, using everything from waste products to mushroom fibres to create lasting materials. A little research can go a long way in improving your construction project’s environmental footprint.
Potential Challenges of Adapting to Construction Innovations
Integrating eco-innovations into the construction industry is not without challenges and requires careful planning and consideration. One hurdle is the resistance to change within established construction practices. The initial costs associated with incorporating sustainable materials and technologies may also be high, discouraging widespread adoption.
The long-term benefits of eco-friendly practices, however, are worth these upfront costs. Educating staff and suppliers on these investment benefits is crucial.
Process improvement also plays a large role in easing the transition to eco-innovations. Implementing optimised construction processes not only reduces costs but also leads to resource conservation and emissions reduction. By streamlining the way you use materials, you can enhance efficiency and analyse the effects to report tangible, environmental benefits.
This can garner team buy-in and showcase your efforts to external stakeholders. You can also respond more quickly to industry changes, meeting evolving eco-friendly compliance requirements more easily.
The Future of Green Construction
The future of construction involves a significant shift toward greener practices all around. As concerns about climate change escalate, larger urban centres like Brisbane are advocating for climate-positive infrastructure. The emphasis will continue to be placed on construction materials with a reduced carbon footprint, creating structures that align with climate goals worldwide.
The push for greener construction reflects a broader recognition within the built environment that sustainable materials are integral to constructing resilient and ecologically responsible structures that can withstand the trials and tribulations of the future.
