Beyond Green: What Regenerative Building Actually Means
Sustainability in construction usually means "do less damage." Use less energy. Produce less waste. Emit fewer carbon emissions. Regenerative building takes this further. It asks: what if the buildings we construct actually improved the environment?
Jess Glowacki of EcoPhi has been working at the forefront of this movement. On the First Shift Podcast, she explained how materials like hemp, bamboo, mycelium, and reclaimed bio-based composites are not just alternatives to concrete and steel. They are materials that sequester carbon, improve indoor air quality, and create healthier living environments.
For contractors, this is not just an environmental conversation. It is a business opportunity.
The Materials You Need to Know About
Hempcrete
Hempcrete is a bio-composite made from the woody core of the hemp plant (hemp hurd) mixed with a lime-based binder and water. It is not structural on its own. It is used as insulation and infill within a structural frame (typically timber).
Key properties:
- Carbon negative. Hemp absorbs CO2 while growing, and the lime binder continues to absorb CO2 as it cures. A hempcrete wall is literally pulling carbon out of the atmosphere.
- Excellent insulation. R-values of 2.5 to 3.0 per inch, comparable to many conventional insulation materials.
- Moisture regulation. Hempcrete breathes. It absorbs and releases moisture, which prevents mold and creates healthier indoor environments.
- Fire resistant. Hempcrete does not burn easily. It chars rather than combusting, giving it favorable fire ratings.
- Pest resistant. Insects and rodents do not eat hempcrete. No need for chemical treatments.
Challenges for contractors:
- Limited availability of hemp hurd in some regions
- Requires education on proper mixing ratios and application techniques
- Building code acceptance varies by jurisdiction
- Longer curing times compared to conventional wall systems
- Currently more expensive per square foot than conventional framing and insulation
Bamboo
Engineered bamboo is emerging as a serious structural material:
- Tensile strength comparable to steel. Bamboo fibers are remarkably strong for their weight.
- Rapid renewability. Bamboo reaches maturity in 3 to 5 years, compared to 20 to 50 years for timber.
- Carbon sequestration. Bamboo absorbs more CO2 per acre than most tree species.
- Versatile applications. Structural beams, flooring, cladding, cabinetry, and decorative elements.
Challenges:
- Supply chain limitations in North America
- Building code recognition still developing
- Requires specific engineering for structural applications
- Quality varies significantly between suppliers
- Client education needed on durability and maintenance
Mycelium (Mushroom-Based Materials)
This one sounds futuristic, but it is already in production:
- Mycelium insulation. Grown on agricultural waste, these panels provide thermal and acoustic insulation.
- Mycelium packaging and formwork. Replacing polystyrene foam in packaging and concrete formwork.
- Structural composites. Researchers are developing load-bearing mycelium composites, though these are not commercially available yet.
Other Regenerative Materials
- Rammed earth. Ancient technique, modern performance. Thermal mass, durability, and striking aesthetics.
- Straw bale. Excellent insulation, low cost, and carbon sequestering. Requires proper moisture management.
- Reclaimed and salvaged materials. Reusing existing materials is inherently regenerative. Old-growth timber, antique brick, and salvaged steel have both environmental and aesthetic value.
The Business Case for Contractors
Growing Client Demand
A significant and growing percentage of homebuyers consider environmental impact when making purchasing decisions. Younger buyers, who are increasingly entering the custom home market, are willing to pay a premium for healthier, more sustainable homes.
Premium Pricing
Regenerative building commands higher margins. Clients who choose these materials are typically well-researched, committed, and less price-sensitive than the average customer. They value expertise and are willing to pay for a contractor who understands the materials.
Differentiation
In a market where most contractors offer essentially the same service, specializing in regenerative building sets you apart immediately. You are not competing on price with every other framer in town. You are offering something most contractors cannot.
Future Regulations
Building codes are moving toward stricter energy and carbon requirements. Contractors who learn regenerative building methods now will be ahead of the curve when these requirements become mandatory. In some jurisdictions, carbon embodied in building materials is already part of the regulatory conversation.
How to Get Started
You do not need to become a full-time regenerative builder overnight. Here is a practical path:
Step 1: Educate yourself. Take a hempcrete workshop or a natural building course. Many are available online and cost less than $500. The knowledge alone makes you more valuable in client conversations.
Step 2: Partner with specialists. Find a local hemp supplier, a natural building consultant, or an architect who specializes in regenerative design. Build relationships before you need them.
Step 3: Start small. Offer hempcrete insulation as an option on your next renovation project. Build a small structure (a garden shed, a studio) using regenerative materials. Get hands-on experience without the risk of a major project.
Step 4: Document and share. Take photos, write about the process, share it on social media. You will attract clients who are specifically looking for this expertise.
Step 5: Build your reputation. As you complete projects, collect testimonials, case studies, and performance data. This evidence-based portfolio is far more convincing than a sales pitch.
Jess Glowacki's full conversation on the First Shift Podcast is an excellent starting point for understanding the regenerative building landscape.
The Bottom Line
Regenerative building is not a fad. It is the direction the industry is heading. The contractors who invest in learning these materials and methods now will have a significant competitive advantage in the coming years.
