Organized every 2 years, during years with no Indoor Air conference, Healthy Buildings conferences bridge the gap between science and profession, making it one of the most influential conferences on best-practice sustainable solutions for the indoor environment.

The 12^th 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.

In this webinar, we addressed the opportunities to use novel materials (from advanced functional nano-materials to bio-based building materials) as building components to actively/passively manage the IAQ, for example, through active paint, wallboards, and textiles coated with advanced sorbents or catalysts and quantify their potential, based on the assessment framework developed in the IEA EBC

Building airtightness tests have become very common in many countries, either to comply with minimum requirements of regulations or programmes, or to justify input values in calculation methods. Thus, it has become very important to understand and quantify the reliability of these tests.

IEA Energy in Buildings and Communities (EBC) research projects are examining building energy codes, exploring data utilization for improving energy efficiency, and investigating air cleaning technologies.

In this webinar, we addressed the opportunities offered by smart ventilation strategies, which include a wide range of systems depending on the type of sensing parameters (CO₂, humidity, occupancy, etc.), the type of sensing combinations, the type of installation (centralized/decentralized), the types of control algorithms, etc.

In the context of energy use reduction, low energy buildings are becoming more widespread. This kind of construction requires a good envelope airtightness to prevent uncontrolled leakages of conditioned air leading to energy losses.

The conference "IAQ 2020: Indoor Environmental Quality Performance Approaches Transitioning from IAQ to IEQ”, organized by ASHRAE and AIVC, was held in Athens, Greece on 4-6 May 2022. The conference was also the 9^th TightVent and 7^th venticool conference.
