An EPD is read in five steps: the cover data, the declared unit, the module scope, the GWP rows and the comparability conditions. Red flags, and moving EPD data into a building LCA.
Read moreThere are three EPD types: product-specific, manufacturer average and industry average. Representativeness, the credit difference in green building schemes, tender expectations, cost and the strategy for moving from an average to a product-specific declaration.
Read moreAggregate is one of the lowest-carbon construction materials per tonne, yet its volume makes it visible in a building's balance. An aggregate EPD is prepared with a 1 tonne declared unit; diesel, electricity and transport distance set the result.
Read moreA product's embodied carbon is the sum of its A1–A3 emissions per declared unit. The formula, the A1/A2/A3 split, pulling values from EPDs, the biogenic carbon distinction and a worked example for 1 m² of wall.
Read moreA concrete EPD is prepared under EN 15804+A2 with the complementary PCR EN 16757: a 1 m³ declared unit, a mix per strength class, the cement EPD as an input, B1 carbonation and C/D scenarios.
Read moreOne line decides ceramic impact: the kiln. What glazing, drying and thin-body technology actually do to the total.
Read moreEPDs are shifting from marketing document to tender pre-qualification requirement. How specifications are written, and how to meet them.
Read moreA BIM model already contains a bill of quantities. The real obstacle to connecting it to LCA is not software but material mapping.
Read moreTrying to optimise every material wastes effort. The Pareto distribution, the weight of the structure and the five decisions that actually move the number.
Read moreBREEAM assesses materials by building element rather than one by one. The logic of Mat 01 and what it means for a manufacturer.
Read moreLEED's materials credits tie points directly to product EPDs. The different weight of product-specific and industry-average EPDs, and embodied carbon reduction.
Read moreAs operational carbon falls, embodied carbon has become the dominant share. Which modules count, and which benchmarks apply?
