Ventilation and process exhaust recovery therefore qualify on both axes of the SEU definition: substantial consumption <em>et<\/em> large improvement potential. Once designated, the SEU must have documented operating criteria, calibrated metering, and competent operators.<\/p>\n<h2>From Standard to Savings<\/h2>\n<ul>\n<li>Define the EnPI before installing recovery: e.g. exhaust heat reclaimed (kW) normalized by outdoor temperature and occupancy.<\/li>\n<li>Apply the method from our <a href=\"https:\/\/www.26yc.com\/fr\/industrial-waste-heat-recovery-case\/\">industrial waste heat recovery case<\/a> to a building exhaust stream.<\/li>\n<li>Tie recovery to a <a href=\"https:\/\/www.26yc.com\/fr\/heat-pump-waste-heat-recovery\/\">Pompe \u00e0 chaleur<\/a> or <a href=\"https:\/\/www.26yc.com\/fr\/high-temperature-heat-pump-heat-recovery\/\">high-temperature heat pump<\/a> to lift low-grade recoverable heat to useful temperature &mdash; then track the combined EnPI.<\/li>\n<\/ul>\n<h2>Auditability<\/h2>\n<p>The standard requires demonstrated <em>improvement<\/em>, not just a system on paper. Meter the recovery loop, normalize for weather and activity, and retain records so the claim survives audit.
