Generate an illustration for an article following this concept: ÖKOBAUDAT: Germany’s EPD Data Hub, Explained Selling into Germany or EU projects with German public clients on the team often hinges on one quiet gatekeeper: ÖKOBAUDAT. If your product’s EPD is findable there, you glide through LCA checks in the BNB system and many design workflows. If it is not, teams stall, swap in a competitor, or push the bid to “later.” Here is how this data hub works, what it hosts, and how to make it speed sales instead of slowing them. Ensure that you use no text, as this illustration will be used on international translations of the article.. Use an illustrative style (e.g. isometic) and don't generate in a photorealistic style.

Generate an illustration for an article following this concept: EC3: The EPD data hub architects use If buyers cannot find your product’s EPD where they look first, you risk being swapped out before the bid warms up. Building Transparency’s EC3 has become the default lookup for teams screening embodied carbon, from design models to owner checklists. It is broad, neutral, and plugged into real project tools. It is not perfectly current. Here is how to treat EC3 as a powerful signal and plan around its timing gaps without slowing sales. Ensure that you use no text, as this illustration will be used on international translations of the article.. Use an illustrative style (e.g. isometic) and don't generate in a photorealistic style.

Generate an illustration for an article following this concept: Dutch National Environmental Database, Explained If the Netherlands is on your sales map, the Nationale Milieudatabase (NMD) is your scoreboard. Designers, contractors, and public clients pull product data from it to calculate MPG for buildings and MKI for civil works. Having your EPDs present and correct here turns sustainability paperwork into commercial traction, not a compliance drag. Ensure that you use no text, as this illustration will be used on international translations of the article.. Use an illustrative style (e.g. isometic) and don't generate in a photorealistic style.
