They eliminate the need for manual rebalancing of the ductwork and repeated on-site interventions.<\/p><p>The use of VAV dampers also enables accurate monitoring of actual airflow and dynamic control.

When demand decreases, pressure remains artificially high in the ductwork. VAV dampers then compensate by closing significantly to maintain their airflow setpoints.<\/p><p>This operation generates unnecessary pressure losses and increased fan energy consumption. Several studies show that dynamic control based on the actual position of VAV dampers allows pressure to be adjusted to real demand. The principle is to use damper position feedback as an indicator of ductwork load. The air handling unit then adjusts fan speed to keep VAV dampers within an optimal operating range.<\/p><p>This approach repositions dampers in an intermediate operating zone that is more stable and efficient. The ductwork then operates at the minimum required pressure, without overpressure.<\/p><p>The energy benefit is immediate: fan power decreases significantly with pressure. In commercial buildings, energy savings typically range from 20% to 50%, with some cases showing reductions of up to 60% to 65%.<br \/>Beyond reducing energy consumption, this control strategy also improves acoustic comfort and airflow stability. It reduces mechanical stress on VAV actuators. Damper position thus becomes a key indicator of the system\u2019s energy performance. An optimized ductwork system is one where VAV dampers are neither too closed nor fully open.<\/p><p>Source: <a href=\"https:\/\/www.rehva.eu\/rehva-journal\/chapter\/vav-system-with-genuinely-demand-controlled-fans\" target=\"_blank\" rel=\"noopener\">https:\/\/www.rehva.eu\/rehva-journal\/chapter\/vav-system-with-genuinely-demand-controlled-fans<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-e912830 e-con-full e-flex e-con e-child\" data-id=\"e912830\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-414fafc e-con-full e-flex e-con e-child\" data-id=\"414fafc\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-e03fa21 elementor-widget elementor-widget-image\" data-id=\"e03fa21\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image.webp\" data-elementor-open-lightbox=\"yes\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6Mjc3MTksInVybCI6Imh0dHBzOlwvXC9mMmEuZnJcL3dwLWNvbnRlbnRcL3VwbG9hZHNcLzIwMjZcLzAyXC9OZXctdmVudGlsYXRpb24tbW9uaXRvcmluZy1FTi1JbWFnZS53ZWJwIn0%3D\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1698\" height=\"1082\" src=\"https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image.webp\" class=\"attachment-full size-full wp-image-27719\" alt=\"New ventilation monitoring EN Image\" srcset=\"https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image.webp 1698w, https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image-300x191.webp 300w, https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image-1024x653.webp 1024w, https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image-768x489.webp 768w, https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/New-ventilation-monitoring-EN-Image-1536x979.webp 1536w\" sizes=\"(max-width: 1698px) 100vw, 1698px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-267f14a e-con-full left_separator e-flex e-con e-child\" data-id=\"267f14a\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-9806e79 e-con-full e-flex e-con e-child\" data-id=\"9806e79\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-5b229ae e-con-full e-flex e-con e-child\" data-id=\"5b229ae\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1fee82d elementor-widget__width-initial elementor-widget elementor-widget-heading\" data-id=\"1fee82d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<div class=\"elementor-heading-title elementor-size-default\">Airflow diversity in commercial buildings\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-0f17b70 e-con-full e-flex e-con e-child\" data-id=\"0f17b70\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-93fa3e1 e-con-full e-flex e-con e-child\" data-id=\"93fa3e1\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0120bcb dynamic elementor-widget elementor-widget-text-editor\" data-id=\"0120bcb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Airflow diversity in commercial buildings, particularly in office spaces, is not a regulatory requirement.<\/p><p>It is primarily a design method used by engineering consultants to avoid sizing ventilation systems based on the assumption that all zones operate simultaneously at maximum airflow. This approach, based on variations in occupancy and indoor air quality, avoids systematically oversizing for peak loads.<\/p><p>Airflow diversity helps optimize system sizing and reduce air handling unit capacity. The AHU becomes more compact and cost-effective, providing direct project savings. It also allows ventilation to better match actual building usage. With sensors, VAV dampers, and a control system, energy is used more efficiently, resulting in operational savings.<\/p><p>However, airflow diversity must be applied with caution. If poorly implemented, it can quickly lead to underperforming ventilation systems. An overly optimistic diversity factor may result in insufficient airflow during real high-occupancy conditions (meetings, densification, return to office), leading to degraded indoor air quality and comfort.<\/p><p>This can cause design issues that are difficult to correct during operation. If actual occupancy patterns differ from initial assumptions, an undersized ventilation system may not be recoverable without replacing the air handling unit.<\/p><p>In constantly evolving commercial buildings, a fixed diversity assumption quickly becomes obsolete. Without flexibility or capacity margin, the system may become unsuitable or even non-compliant with indoor air quality and energy performance requirements.<\/p><p>The main pitfall is to consider airflow diversity as an alternative to control. Without precise control (VAV, sensors, BMS), the risks of airflow imbalance, overpressure, or under-ventilation are significant. It is therefore essential to adapt system design by implementing connected and intelligent solutions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-e41eb9a e-con-full e-flex e-con e-child\" data-id=\"e41eb9a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-8bb99b5 e-con-full e-flex e-con e-child\" data-id=\"8bb99b5\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-f8b1eb5 e-con-full no-shape-toc e-flex e-con e-child\" data-id=\"f8b1eb5\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-a493d9d elementor-widget__width-initial elementor-widget elementor-widget-heading\" data-id=\"a493d9d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<div class=\"elementor-heading-title elementor-size-default\">2<\/div>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9e5e5a1 elementor-widget__width-initial mp0 elementor-widget elementor-widget-heading\" data-id=\"9e5e5a1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Regulatory <\/br>context<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-64f83bd elementor-hidden-tablet elementor-hidden-mobile_extra elementor-hidden-mobile elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"64f83bd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"712\" height=\"200\" src=\"https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/Mask-group.webp\" class=\"attachment-full size-full wp-image-25575\" alt=\"wave image\" srcset=\"https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/Mask-group.webp 712w, https:\/\/f2a.fr\/wp-content\/uploads\/2026\/02\/Mask-group-300x84.webp 300w\" sizes=\"(max-width: 712px) 100vw, 712px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-142afe7 e-con-full e-flex e-con e-child\" data-id=\"142afe7\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-12209ea elementor-widget__width-initial red_horizontal_line elementor-widget elementor-widget-text-editor\" data-id=\"12209ea\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\tIndoor air quality and air renewal\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-676b1a8 dynamic elementor-widget elementor-widget-text-editor\" data-id=\"676b1a8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Indoor air quality (IAQ) is a major public health issue, especially in commercial buildings where people spend up to 85% of their time.
