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 -2.09 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.

Service Life — the B4 Replacement Input

50 years · EPD reference service life

≈2 installations 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.

Comparison Status

The record contains the basic metadata required for a controlled comparison. Products must still perform the same function and use compatible units, PCRs and lifecycle scope.

Design & Specification Notes

Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.

Wet-pressed concrete walling for garden, boundary and retaining walls in hard landscaping.

Typical Uses

  • Paths & paving
  • Public realm surfaces
  • Permeable groundworks

Key Performance

Durable external surface with slip resistance.

Specification Actions

  • Specify GGBS/PFA cement replacement (target: 50%+ replacement).
  • Request EPD showing embodied carbon per m3.
  • Calculate transport distances for primary materials.

Indicative Health & Indoor Air

low Risk

Inert concrete; no in-use emissions of concern.
