For critical ventilation where cross-contamination is unacceptable, a <a href=\"https:\/\/www.26yc.com\/es\/enthalpy-recovery-vs-membrane\/\">membrane core<\/a> is the compliant non-rotating option. These Ecodesign floors align with the <a href=\"https:\/\/www.26yc.com\/es\/eu-epbd-zero-emission-buildings\/\">EPBD zero-emission building<\/a> push &mdash; efficient recovery is now table stakes in the EU market.<\/p>\n<h2>Labelling and Market Reality<\/h2>\n<p>The Ecodesign floors are not just paperwork; they reshape what can be sold. Because the efficiency bonus E relaxes the specific fan power limit, a unit with a 78% core gains compliance headroom over a bare 73% unit, which matters as fans are pushed to lower SFP. Manufacturers must publish a product information sheet documenting thermal efficiency and fan power, and that sheet is what a designer cites at spec time. For non-residential AHUs, EN 13053 governs how the recovery section is rated within the whole unit, including the pressure drop it adds. Residential bidirectional units face the same 73% logic but with a tighter SFP reference. In practice, specifying a membrane or high-efficiency plate core that clears 73% comfortably satisfies the regulation and aligns with the broader EPBD push toward zero-emission buildings, where efficient recovery is now expected rather than optional.<\/p>\n<h2>Preguntas frecuentes<\/h2>\n<p><strong>What does EU Ecodesign Regulation 1253\/2014 require?<\/strong><br \/>Ventilation units above 30 W fan power must carry a heat recovery system meeting minimum thermal efficiency, 73% for plate or wheel and 68% for run-around.<\/p>\n<p><strong>How does higher efficiency help compliance?<\/strong><br \/>An efficiency bonus relaxes the specific fan power limit, giving design headroom as fans are pushed to lower SFP.<\/p>\n<p><strong>Which test standards apply?<\/strong><br \/>EN 308, EN 13053 for air-handling units, and EN 13141-7 for residential units.<\/p>\n<p><strong>Can a membrane core comply?<\/strong><br \/>Yes.
