The eNviMat system (Environmental Inventory of Materials), commonly used for environmental assessments in construction and building materials, typically aligns with lifecycle assessment stages found in standards like ISO 14040/14044 and EN 15804. Its stage split includes:
Product Stage:
- A1 – Raw Material Supply: Extraction and processing of raw materials, including recycled materials.
- A2 – Transport: Transportation of raw materials to the manufacturing site.
- A3 – Manufacturing: Processes involved in creating the construction product.
Construction Process Stage:
- A4 – Transport to Site: Emissions related to transporting the product to the construction site.
- A5 – Construction and Installation: Impacts of installation, including waste generated and energy used on-site.
Use Stage:
- B1 – Use: Direct emissions or impacts during the product’s use phase.
- B2 – Maintenance: Energy, water, or materials required for maintaining the product.
- B3 – Repair: Impacts related to repairs over the product’s lifespan.
- B4 – Replacement: Impacts from replacing the product or components during its lifetime.
- B5 – Refurbishment: Larger-scale updates or renovations involving the product.
- B6 – Operational Energy Use: Energy required during the operational phase of the product.
- B7 – Operational Water Use: Water used during the operational phase.
End-of-Life Stage:
- C1 – Deconstruction and Demolition: Impacts related to dismantling or removing the product.
- C2 – Transport: Transportation of waste materials to recycling or disposal facilities.
- C3 – Waste Processing: Processes involved in recycling or repurposing materials.
- C4 – Disposal: Final disposal of materials in landfills or other waste streams.
Beyond the System Boundary:
- D – Benefits and Loads Beyond the System Boundary: Credits for recycling or energy recovery, representing environmental benefits outside the immediate lifecycle.
These stages are consistent with EN 15804, widely used in construction and building product LCAs, and eNviMat aligns with this structure to provide comprehensive assessments of environmental impacts.
