Adjustable height and width ensure compatibility with base building elements, while precision-engineered components guarantee a perfect fit. Its modular design offers long-term adaptability.
Interpretation
The product stage (A1-A3) shows the highest environmental impact, primarily due to raw material manufacturing and manufacturing energy use. For products with high manufacturing energy impacts, switching to renewable energy sources is recommended. Since raw materials significantly impact the environmental footprint, DIRTT should consider using alternative materials with lower environmental impacts. They should also seek suppliers who use sustainable manufacturing techniques and renewable energy. These changes would improve the overall sustainability of DIRTT's products.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
