Passivhaus System Certification
The MODULAR system is certified by the Passivhaus Institute from Darmstadt to the world's strictest thermal, airtightness, and ventilation standards. Over 2,000 tracked parameters considered.
EPD International
Full lifecycle transparency audited by a third party. Confirms carbon-negative at -101 kg CO2e/m² from raw material to end of life.
FSC & PEFC
Chain-of-custody on all applicable timber. Timber traceable from sustainably managed European forests to your home.
Our principles
Questions you might be asking.
THE MATERIALS
98% organic, sustainably sourced materials. The system includes: structural timber frame, ultra-efficient wood-fiber insulation, airtightness membranes, triple-glazed windows, and exterior cladding (Yakisugi charred wood or Lunawood Thermowood). Every layer is selected for thermal performance, health safety, and environmental impact.
All primary materials are sourced from certified European suppliers, ensuring full traceability and compliance with EU environmental standards.
See how these materials deliver Passivhaus performance.From certified partners across Europe, around 98% by weight from within the EU. Germany for insulation, sheathing and airtightness; Finland for C24 structural timber and Lunawood cladding; Belgium for interior panels; Austria for glulam. A few specialist components, such as the EPDM roof membrane, come from outside the EU where no European equivalent exists.
Every supplier operates within EU standards and regulations.
Learn about our company and factory.The MODULAR construction system is certified by the Passive House Institute for its thermal envelope and connection details. The EPDs separately document environmental impacts for the declared building elements.
Additionally, our wood materials carry FSC and PEFC chain-of-custody certification where applicable, proving the timber comes from sustainably managed forests.
Understand what Passivhaus certification requires.THE SUSTAINABILITY
Timber stores carbon absorbed during tree growth. BIOBUILDS’ external-wall EPD records -101 kg CO2e per m² for the production stage, from raw materials through manufacturing.
Cement production alone accounts for 8% of global CO2 emissions. Steel requires extreme energy to produce. Wood is incredibly more sustainable, more efficient, healthier for occupants, and grows back. It's better by every measure.
Read about our environmental impact.FSC (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification) are independent standards that guarantee timber comes from sustainably managed forests: forests that are replanted, biodiversity-protected, and regularly audited.
BIOBUILDS' wood materials carry these certifications where applicable, ensuring your home did not contribute to deforestation. These are material-level certifications, meaning they apply to the individual wood products that go into each module.
