EcoCocon Straw Wall Panel

A load-bearing prefabricated wall panel of a slotted softwood frame densely packed with compressed straw, acting as structure and insulation in one element. Panels are made to order in Kybartai, Lithuania and delivered as a closed system for rapid dry assembly. The declaration covers a weighted average of the six panel types — Standard, Braced, Sill, Lintel, Column and Inclined.

Product Evidence

Evidence currently held for the EcoCocon product record.

EcoCocon

Recorded Carbon Result

-101kgCO₂e/m²

A1–A3 GWP-total per m² of panel. Negative because 119 kgCO2e of biogenic carbon is stored in the straw. That store is not permanent: the EPD declares C3 = +112 kgCO2e when the panel is processed at end of life, so the cradle-to-grave picture is close to neutral rather than strongly negative.

Indicator: GWP-total

A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

* EPD transport and installation scenario, not this project's. Not declared: use. Module D shows potential impacts or benefits from reuse, recovery or recycling after the product's assessed life. It is reported separately and never added to A-C. Do not compare bar lengths between materials. Each chart may use a different scale and declared unit.

* A4/A5 are EPD scenarios, not project-specific results. Module D is outside the A–C system boundary and is not added to A–C. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.

* Includes the EPD’s A4/A5 scenario assumptions, not project-specific transport or installation. This is the aggregation the proposed Part Z applies upfront limits to. The A1–A3 figure includes declared biogenic storage of -119 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.

Service Life — the B4 Replacement Input

75 years · EPD reference service life

The EPD declares a 75-year reference service life.

≈1 installation over a 60-year building study period.

B4 (replacement) follows the building, not the product: an assessor multiplies replacement cycles by project quantities. This record supplies the service life and does not compute B4.
