How Relic Rammed Earth Board Supports Green Building Certifications (LEED, BREEAM)

Walk into any modern building today, and you'll likely notice something different from structures built just a decade ago: a quiet emphasis on intentionality . It's in the way natural light floods the rooms, the materials underfoot feel both sturdy and earthy, and the air somehow feels fresher—even in the heart of a bustling city. This shift isn't just about aesthetics; it's about a growing recognition that the buildings we live and work in shape not just our daily experiences, but the health of our planet, too. As architects, builders, and homeowners increasingly prioritize sustainability, green building certifications like LEED and BREEAM have become more than just badges of honor—they're roadmaps for creating spaces that are kind to the environment, healthy for people, and resilient for future generations.

But here's the thing about green building: it's only as strong as the materials that go into it. You can design the most energy-efficient floor plan, but if the walls are made from resource-heavy, emissions-intensive materials, that efficiency gets undercut. That's where innovative building materials step in—and few have generated as much buzz in sustainable construction circles lately as Relic Rammed Earth Board. A modern take on an ancient technique, this material isn't just a nod to tradition; it's a powerhouse of sustainability, designed to help projects not just meet, but exceed, the rigorous standards of LEED and BREEAM. Let's dive into how this unassuming board is redefining what it means to build green.

Understanding LEED and BREEAM: The Gold Standards of Green Building

Before we get into the specifics of Relic Rammed Earth Board, let's make sure we're on the same page about the certifications we're talking about. LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method) are the two most widely recognized green building rating systems in the world. Think of them as report cards for sustainability—they evaluate buildings based on a range of criteria, from energy use to material sourcing, and award points that translate to certification levels (like LEED Platinum or BREEAM Excellent).

LEED, developed by the U.S. Green Building Council, is all about "whole-building" sustainability. It focuses on categories like Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, and Water Efficiency, with points awarded for actions like using recycled materials, reducing energy consumption, or improving air quality. BREEAM, hailing from the UK, takes a similar holistic approach but places extra emphasis on health and wellbeing, management practices, and ecological impact. Both certifications push builders to think beyond "less harm" and aim for "positive impact"—and both are notoriously tough to achieve without careful material selection.

So, what makes a material "certification-worthy"? It needs to check multiple boxes: low embodied carbon (the emissions generated during its production), renewable or recycled content, durability (to reduce replacement waste), and maybe even benefits like thermal insulation or improved indoor air quality. And that's where Relic Rammed Earth Board shines. Let's start by understanding what this material is, exactly.

What Is Relic Rammed Earth Board? A Blend of Old Wisdom and New Innovation

Rammed earth is one of the oldest building techniques on the planet. For centuries, civilizations from China to Africa used a simple mix of soil, water, and sometimes straw, compressed into forms to create thick, sturdy walls. These structures were naturally insulated, fire-resistant, and deeply connected to the local landscape—they quite literally came from the earth . But traditional rammed earth has its limitations: it's heavy, requires on-site mixing, and can be tricky to integrate into modern, multi-story designs.

Relic Rammed Earth Board reimagines this ancient method for the 21st century. It's a prefabricated panel made by compressing a carefully engineered blend of natural materials—locally sourced soil, recycled aggregates, and a small amount of natural binders—into thin, lightweight boards. The result? A material that retains all the sustainability benefits of traditional rammed earth but adds modern perks: flexibility (it can be cut and shaped like wood), durability (resistant to mold, pests, and weathering), and ease of installation (no messy on-site ramming required). It's like taking the best parts of history and upgrading them with today's engineering smarts.

But what really sets Relic Rammed Earth Board apart is its commitment to circularity . From sourcing to manufacturing to end-of-life, every step is designed to minimize environmental impact. The soil used is often excavated from local construction sites (otherwise destined for landfills), the binders are plant-based, and the manufacturing process uses 80% less energy than producing materials like Fair-Faced Concrete. Even better, at the end of a building's life, the boards can be crushed and reused as aggregate—closing the loop on waste.

Sustainable Features of Relic Rammed Earth Board: Why It's a Certification Powerhouse

To understand how Relic Rammed Earth Board supports LEED and BREEAM, let's break down its key sustainable features. Each one aligns with specific certification criteria, making it easier for projects to rack up points. Here's a closer look:

1. Low Embodied Carbon

Embodied carbon—the total CO2 emitted during a material's production, transportation, and installation—is a big deal in green building. Traditional materials like concrete or steel are major culprits here; producing a single ton of concrete, for example, releases about 0.8 tons of CO2. Relic Rammed Earth Board, by contrast, has an embodied carbon footprint of just 0.1 tons per ton—8 times lower. Why? Because it uses locally sourced materials (cutting down on transportation emissions), requires minimal processing, and avoids the high-temperature kilns or furnaces used in making cement or metal. For certifications like LEED (which rewards Materials and Resources credits for low-carbon materials) and BREEAM (which grades materials on their life-cycle impacts), this is a huge win.

2. High Recycled and Renewable Content

LEED's MR Credit 4.1 (Building Product Disclosure and Optimization) and BREEAM's Mat 02 (Life Cycle Impacts) both reward materials with high recycled or renewable content. Relic Rammed Earth Board checks this box with gusto: up to 40% of its composition is recycled material (think crushed concrete from demolished buildings or glass from local recycling programs), and the remaining 60% is natural, renewable soil. Compare that to Epoch Stone, another popular sustainable material, which typically contains only 20-25% recycled content. This high recycled percentage not only reduces reliance on virgin resources but also diverts waste from landfills—a double win for the planet and certification points.

3. Thermal Mass and Energy Efficiency

Ever walked into a cave on a hot day and felt instantly cooler? That's thermal mass at work—the ability of a material to absorb, store, and slowly release heat. Relic Rammed Earth Board has excellent thermal mass properties, which means buildings using it require less energy for heating and cooling. In summer, the boards absorb heat during the day and release it at night, keeping interiors cool without cranking up the AC. In winter, they trap warmth from sunlight or heating systems, reducing the need for constant heating. This directly supports LEED's Energy and Atmosphere credits (like EA Credit 1: Optimize Energy Performance) and BREEAM's Energy category, which rewards buildings that reduce operational energy use. In fact, studies show that projects using Relic Rammed Earth Board can cut heating and cooling costs by 20-30% compared to those using standard drywall or concrete.

4. Indoor Air Quality (IAQ) Benefits

LEED and BREEAM both place a premium on indoor air quality, recognizing that people spend 90% of their time indoors, and poor IAQ can lead to health issues like allergies or headaches. Many building materials off-gas volatile organic compounds (VOCs)—chemicals found in paints, adhesives, and even some flooring. Relic Rammed Earth Board, however, is 100% VOC-free. Its natural composition (no synthetic glues or finishes) means it doesn't release harmful chemicals. In fact, it actually improves IAQ by regulating humidity: the porous structure of the boards absorbs excess moisture from the air (preventing mold growth) and releases it when the air is dry, acting like a natural humidifier. This is a boon for LEED's Indoor Environmental Quality credits (like EQ Credit 1: Indoor Air Quality Assessment) and BREEAM's Health and Wellbeing category, which prioritizes spaces that support occupant health.

5. Durability and Longevity

Sustainability isn't just about what a material is made of—it's about how long it lasts. A material that needs to be replaced every 10 years is less sustainable than one that lasts 50. Relic Rammed Earth Board is built to endure: it's resistant to mold (thanks to its low moisture absorption), pests (termites and rodents don't find it appetizing), and weathering (UV rays won't fade its natural color). In fact, traditional rammed earth structures have stood for centuries—think of the Great Wall of China's rammed earth sections—and modern Relic boards are engineered to last just as long. This durability reduces the need for frequent replacements, cutting down on waste and supporting LEED's MR Credit 2: Construction Waste Management and BREEAM's Mat 03: Material Efficiency credit, which rewards materials that minimize lifecycle waste.

How Relic Rammed Earth Board Supports LEED Certification

Now that we've covered the features, let's get specific about LEED. LEED certification is awarded on a points system, with projects earning points across several categories. The more points, the higher the certification level (Certified, Silver, Gold, Platinum). Relic Rammed Earth Board can contribute to points in at least five key LEED categories—let's break them down:

1. Materials and Resources (MR)

LEED's Materials and Resources category is all about reducing waste, using sustainable materials, and supporting circular economies. Relic Rammed Earth Board shines here:

• MR Credit 2: Construction Waste Management – By using recycled aggregates from construction waste, the board helps projects divert waste from landfills. LEED awards points for diverting 50% or more of construction waste; Relic Rammed Earth Board can help projects hit 60% or higher.
• MR Credit 4: Building Product Disclosure and Optimization – Environmental Product Declarations (EPDs) – Relic Rammed Earth Board comes with third-party verified EPDs, which document its environmental impact. LEED awards points for using products with EPDs, and the board's low embodied carbon score makes it a standout here.
• MR Credit 5: Building Product Disclosure and Optimization – Sourcing of Raw Materials – This credit rewards materials with recycled content or responsibly sourced materials. With 40% recycled content and locally sourced soil, Relic Rammed Earth Board easily meets the criteria for an additional point.

2. Energy and Atmosphere (EA)

As mentioned earlier, the board's thermal mass properties reduce operational energy use. This directly supports EA Credit 1: Optimize Energy Performance , which rewards buildings that exceed baseline energy standards. Projects using Relic Rammed Earth Board have reported energy savings of 15-20% over ASHRAE standards, which can earn 2-3 LEED points.

3. Indoor Environmental Quality (EQ)

With zero VOC emissions and natural humidity regulation, the board contributes to:

• EQ Credit 1: Indoor Air Quality Assessment – By avoiding off-gassing materials, the board helps projects pass pre-occupancy IAQ testing.
• EQ Credit 3: Low-Emitting Materials – LEED requires low-VOC materials in adhesives, paints, and flooring. Since Relic Rammed Earth Board is VOC-free, it helps projects meet this credit without extra effort.

4. Sustainable Sites (SS)

LEED's Sustainable Sites category focuses on reducing a building's impact on its surroundings. Relic Rammed Earth Board's lightweight design reduces the need for heavy foundation work, which minimizes site disturbance—a plus for SS Credit 1: Site Selection (avoiding sensitive habitats) and SS Credit 2: Development Density and Community Connectivity (supporting compact, walkable communities by reducing construction footprint).

5. Innovation (IN)

LEED awards points for innovative strategies not covered by other credits. Relic Rammed Earth Board's unique combination of thermal mass, recycled content, and circularity can qualify for IN Credit 1: Innovation in Design , earning an extra point for projects pushing the boundaries of sustainability.

How Relic Rammed Earth Board Supports BREEAM Certification

BREEAM, while similar to LEED, has its own unique categories and scoring system, with a focus on "sustainable value" across a building's lifecycle. Let's see how Relic Rammed Earth Board contributes here:

1. Materials (Mat)

BREEAM's Materials category evaluates the environmental impact of building materials, from sourcing to disposal. Relic Rammed Earth Board scores highly:

• Mat 01: Responsible Sourcing – BREEAM rewards materials from certified sustainable sources. Relic Rammed Earth Board's local sourcing and recycled content align with the "Responsible Sourcing" criteria, earning a "Very Good" or "Excellent" rating.
• Mat 02: Life Cycle Impacts – This category uses BREEAM's Life Cycle Assessment (LCA) methodology to evaluate a material's total environmental impact. Relic Rammed Earth Board's low embodied carbon, minimal waste, and recyclability give it a low LCA score, translating to high points here.
• Mat 03: Material Efficiency – BREEAM rewards materials that are durable and require minimal maintenance. Relic Rammed Earth Board's 50+ year lifespan and low maintenance needs (no painting or sealing required) earn it top marks.

2. Energy (En)

BREEAM's Energy category focuses on reducing operational energy use and carbon emissions. The thermal mass of Relic Rammed Earth Board helps projects achieve En 01: Energy Efficiency by lowering heating and cooling demands. BREEAM awards points based on energy savings; projects using the board typically see a 15-20% reduction, which can push them into the "Excellent" rating band.

3. Health and Wellbeing (Hw)

BREEAM places a strong emphasis on occupant health, and Relic Rammed Earth Board delivers here:

• Hw 03: Indoor Air Quality – By being VOC-free and regulating humidity, the board helps maintain healthy IAQ levels, which BREEAM rewards with points.
• Hw 06: Daylighting and Glare – While not directly a property of the board itself, the material's natural, warm color reflects light well, enhancing daylighting in spaces. This can contribute to points in BREEAM's Daylighting category when paired with good window design.

4. Management (Ma)

BREEAM's Management category evaluates how well a project is planned and executed sustainably. Using Relic Rammed Earth Board demonstrates a commitment to sustainable material selection, which can support Ma 01: Sustainable Procurement (rewarding projects that prioritize sustainable suppliers) and Ma 02: Construction Site Management (by reducing waste and on-site emissions during installation).

Relic Rammed Earth Board vs. the Competition: How It Stacks Up

To really understand the value of Relic Rammed Earth Board, it helps to compare it to other popular sustainable building materials. Let's take a look at two common alternatives: Fair-Faced Concrete and Epoch Stone.

Fair-Faced Concrete is prized for its raw, industrial aesthetic and durability. But when it comes to sustainability, it falls short. Producing concrete requires cement, which is responsible for 8% of global CO2 emissions. Fair-Faced Concrete also has high embodied carbon (about 0.8 tons per ton) and limited recycled content (typically 10-15%). While it has good thermal mass, it's heavy (increasing transportation emissions) and doesn't offer the IAQ benefits of Relic Rammed Earth Board.

Epoch Stone is a newer sustainable material, made from recycled stone and resin. It has lower embodied carbon than concrete (around 0.3 tons per ton) and 20-25% recycled content. However, the resin binders can off-gas VOCs, and it lacks the thermal mass of Relic Rammed Earth Board, meaning higher operational energy use. It's also not as easily recyclable at end-of-life, as the resin makes separation of materials difficult.

Relic Rammed Earth Board, by contrast, combines the best of both worlds: lower embodied carbon than Epoch Stone, higher recycled content than both, better thermal mass than either, and superior IAQ benefits. It's a reminder that sustainability doesn't have to mean choosing between performance and planet—with the right materials, you can have both.

Real-World Impact: Case Studies of Certified Projects

Talk is cheap—what really matters is how Relic Rammed Earth Board performs in real projects. Let's look at two examples of buildings that used the board to achieve LEED and BREEAM certifications.

It takes waste and turns it into a resource, reduces operational energy use, and supports healthy people and communities. It's a material that works with the planet, not against it.

And it's not alone. The green building materials market is booming, with innovations like MCM Flexible Stone (which offers similar sustainability benefits in a flexible, lightweight format) and foamed aluminium alloy boards (recyclable and energy-efficient) joining the fray. But Relic Rammed Earth Board stands out for its simplicity: it doesn't rely on complex technology or rare materials—just smart engineering and a respect for tradition.
