Major discrepancies are found between countries regarding both the building and ductwork airtightness trends, primarily due to varying national policies, construction practices, and climates. In some countries, minimum airtightness requirements for buildings are included in regulations, such as in U.S. states that have adopted the IECC energy code, which mandates testing to justify airtightness in residential buildings. In Estonia and Germany, achieving high airtightness in the building envelope is encouraged by disadvantageous default values for Energy Performance calculations.
The AIVC and TightVent are pleased to invite you to the webinar titled "Inspection of Ventilation Systems in Non-Residential Buildings", scheduled for June 5, 2025, from 13:30 to 15:00 CET.
Participation is free, but registration is required.
