New law on energy promotes ventilation test for environmental bonus on construction surface. In this new law which foresees evolution of energy regulation the environmental quality is taken into account. Checking ventilation performance is one of the options proposed to obtain the bonus.
Ventilation checks are mandatory in residential since the publication of DTU 68.3 in 2013. Yet ventilation control is mentionned is mentionned in many reports as one important step towards better quality both for IAQ and energy performance. Today still 40% of new installations function unproperly in residential area.
ALLIE'AIR is implementing these tests on ventilation systems since its creation in 2004 and is a training center in this field.
ALLIE AIR is now developping a software for calculation of noise propagation in HVAC ducts.
Duct air tightness measurement is improving in France. New methodogies, application guides and different results from a study on uncertainties and reliability of these measurements (PROMEVENT) are developped. COntact us for more information
Because Indoor Air Quality and Ventilation are related, ALLIE'AIR and MEDIECO have conjointly created a practical training course on "Ventilation & IAQ". More information only available in French
standard EN 16211 on airflow measurement on site is published. ALLIE'AIR actively participated to its writing within WG4 (air diffusion).
Part 1-4 of DTU 68.3 on design and installation of supply & exhaust systems in residential ventilation was at enqury recently and will be published after comments are handled.
