The 41st AIVC – ASHRAE IAQ joint Conference, co-organized by ASHRAE & AIVC, was held on 4-6 May 2022 in Athens. The event drew around 185 participants (in person and remotely) – academic researchers, engineering and consulting firms, industry representatives, people involved in standardisation, policy makers, manufacturers & stakeholders and international organizations.
During the event, two topical sessions dedicated to building and ductwork airtightness were organized.

The 12th International BUILDAIR Symposium will take place on June 25 and 26, 2021 – as a bilingual online conference, in view of the corona situation. The meeting again offers an ambitious programme. Among other things, the presentations will deal with measuring techniques, gluing and sealing difficult details, minimizing the air permeability of materials, quality assurance for very technology-intensive objects and measuring technology for very tall buildings.

Purpose of the work
All too often, we experts and measurement technicians are totally fixated on airtightness issues. Based on three practical cases, I would like to demonstrate that windproofness, minimal convection in the insulation layer, and the convective separation of different structural elements from one another should also be taken into account in order to prevent structural damage.

Even though air leakage assessment is key towards a better energy performance of buildings, Spain has still not established limitations regarding airtightness. National building regulations in Spain are gathered in the National Building Code (CTE), which was first released in 2006 and updated several times so far.

The situation in Switzerland is as follows: Neither the Swiss Energy Act nor cantonal energy acts/energy regulations stipulate a legal measurement of airtightness. The current standards of the Swiss Engineers and Architects Association (Schweizerischer Ingenieur- und Architektenverein, SIA) are the latest standards for architecture. The 2014 edition of SIA Standard 180 defines requirements for airtightness with limit and target values. The limit values are to be complied with in a voluntary measurement.
