More than 200 participants attended the joint 39th AIVC – 7th TightVent – 5th venticool conference held in Juan-Les-Pins, France on September 18-19, 2018. The programme consisted of 3 parallel sessions with contributions from 27 countries and international organisations. Around 150 presentations were given covering the main conference topics namely: Smart Ventilation, Indoor Air Quality (IAQ) and Health relationships,;Ventilation and (building) Airtightness; Ventilative cooling – Resilient cooling.
It has also been a major discussion place for on-going or recently launched projects and initiatives such as the Indoor Environmental Quality – Global Alliance (http://ieq-ga.net/), the IEA EBC annex 80 “Resilient Cooling” (http://annex80.iea-ebc.org/) and the IEA EBC annex 78 “Supplementing Ventilation with Gas-phase Air Cleaning, Implementation and Energy Implications”( http://annex78.iea-ebc.org/).
The “Ventilation and (building) Airtightness” track at the AIVC 2018 conference consisted of 34 presentations organised in 6 sessions, 3 of which were topical sessions with a number of invited presentations:
- Analysing airtightness measurements
- Ductwork airtightness (topical session)
- Integrating uncertainties in declared airtightness results (topical session)
- New methodologies and improvements for airtightness
- Demand controlled ventilation
- Performance of heat recovery ventilation in practice (topical session)
The article available here provides a summary of the main trends and conclusions addressed during the presentations and discussions on the topic of building & ductwork airtightness. Selected presentations are grouped into 3 main themes: Airtightness measurement data; Solutions for ductwork airtightness and; Alternative methods for building airtightness testing.
