Indeed, if ventilation networks are not perfectly airtight, they can lead on the one hand to considerable energy losses (up to 30 % according to ADEME, 2021) and, on the other, to major health risks linked to cross-contamination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consequently, air-tightness is not an option, but a regulatory and technical requirement. That's why Igienair, with its expertise in measurement and control of ventilation networks, is the partner of choice to support maintenance managers, hygienists and manufacturers in this process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why choose a qualified company<\/strong> ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">First of all, ventilation systems in the workplace are subject to specific standards and regulations, such as :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Standard NF EN 12599, which defines methods for measuring the tightness of air networks; ;<\/li>\n\n\n\n<li>Standard NF EN 16798 on performance requirements for ventilation systems; ;<\/li>\n\n\n\n<li>Qualibat 5221 qualification, essential for carrying out compliant measurements in the workplace; ;<\/li>\n\n\n\n<li>Haute Autorit\u00e9 de Sant\u00e9 (HAS) guides, particularly for medical establishments (operating theatres, laboratories).<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">What's more, these requirements are not just about compliance, but also about health safety and optimizing energy costs. Poorly sealed ventilation systems can lead to :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Significant energy losses, as treated air (heated, cooled or filtered) escapes instead of reaching the premises; ;<\/li>\n\n\n\n<li>An imbalance in pressure, which can lead to uncontrolled air infiltration or, conversely, to overpressure that is detrimental to air quality.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The health consequences should not be overlooked. The spread of contaminants (pathogens, fine particles, VOCs) can occur if leaks allow cross-contamination between premises. Non-compliance with standards (HAS, ISO 14644) entails legal risks and penalties in the event of an inspection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En d\u00e9finitive, une <strong>\u00e9tanch\u00e9it\u00e9 d\u00e9fectueuse<\/strong> n\u2019est pas seulement un probl\u00e8me technique, mais aussi <strong>un enjeu \u00e0 la fois \u00e9conomique, sanitaire et r\u00e9glementaire<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Services offered by Igienair<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Drawing on its experience since 2003, Igienair offers a complete range of services related to <a href=\"https:\/\/igienair.com\/en\/expertise\/qai-monitoring\/continuous-qai-monitoring\/\">indoor air quality<\/a>. Our expertise in leak testing is part of a global approach that includes the sealing of ventilation networks. These services are deployed by our 730 employees in over 40 agencies across France, ensuring optimum proximity and responsiveness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>On-site and post-site intervention<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Our experts are involved at every stage of your project. During the construction phase, we carry out intermediate checks to identify and correct any leaks before they become a problem. In the post-construction phase, we carry out the final measurements and deliver the reports needed to validate your aeraulic projects. Our pragmatic approach guarantees reliable, compliant results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In commercial, industrial and healthcare buildings, the tightness of ventilation networks is a key factor in guaranteeing energy performance, air quality and regulatory compliance. As we have seen, poor sealing can lead to energy losses of up to 30 %, pressure imbalances and health risks (cross-contamination, spread of pathogens).
