Frequently Asked Questions
Everything you need to know about EPD verification and LCA consultancy.
What is EPD verification?
EPD verification is a mandatory independent review of an EPD before it can be published. A qualified third-party verifier checks that the LCA model, data, assumptions and report comply with the relevant PCR and EN 15804+A2.
How long does EPD verification take?
Typically 2–4 weeks, depending on the complexity of the product and the completeness of the documentation submitted. Clean, well-prepared studies move fastest.
Which EPD programmes do you verify for?
EPD International (International EPD System), EPD Hub, EPD Global and Building Information Foundation RTS (Finland).
What is the difference between EPD preparation and EPD verification?
EPD preparation involves conducting the LCA and writing the EPD report. EPD verification is the independent review of that report by a qualified third party before publication. EPDlogy offers both — but never for the same project, to preserve verifier independence.
What product types can you verify?
Steel, aluminium, concrete, insulation, facade systems, windows, flooring, ceiling systems, furniture, plastics, paints and more. Experience across a wide range of construction product categories.
