Join us in Madrid for the AIVC 2026 International Workshop on “Climate Change, Ventilation and Resilience”.
Dates: April 21–22, 2026
Location: Madrid, Spain
This international event is organised by the Air Infiltration and Ventilation Centre (AIVC) in collaboration with the Eduardo Torroja Institute for Construction Science (CSIC), and facilitated by INIVE (International Network for Information on Ventilation and Energy Performance).
The AIVC is pleased to announce that the slides from the recent international workshop “Indoor Environmental Quality in Sustainable Buildings” are now available online.
The workshop took place on 1–2 April 2025 in Stuttgart, Germany, and brought together German and international researchers, engineers, and experts to exchange knowledge and share recent developments on indoor environmental quality (IEQ), ventilation, health, and sustainability in buildings.
We’re pleased to announce that the recordings of the AIVC webinar, “Recent Standards and Guidelines on CO₂ Application and Interpretation”, held on March 17, 2025, are now available on our website!
Featured Presentations:
Background on Indoor CO₂ Application – ASHRAE Position Document & ASTM Standard D6245 Andrew Persily (NIST, USA)
Demand-Controlled Ventilation – ISO 17772-1 (EN 16798-1) & ASHRAE Standard 62.1 Bjarne Olesen (DTU, Denmark)

This article follows a first publication presented at the AIVC2022 conference (Handtschoewercker, 2022), with the preliminary results of the RENOVAIR project, that studies the impact of energy renovation works on social housing on the comfort and health of occupants when no requirements are given on IAQ, ventilation and airtightness performances.

Improving the energy performance of a building has been shown to improve health outcomes in fuel poor homes (Wang et al., 2022). However, increasing building air tightness through provision of increased insulation, without due regard to building ventilation, can result in poorer air quality and impaired health for residents, in particular impaired respiratory health (Wimalasena et al., 2021; McGill et al., 2015; Ferguson et al., 2020).

More and more single-family houses are being retrofitted to achieve better energy efficiency levels. In this retrofitting process, the building envelope's airtightness is usually improved, and a ventilation system becomes necessary to create and sustain a healthy indoor air quality (IAQ). However, in France, as in many other western countries, ventilation requirements exist for new dwellings but not for residential retrofitting.

The ingress of naturally occurring radioactive radon gas from the soil into buildings can occur both by convection through any openings in the foundations as a result of pressure differentials and by diffusion across an airtight barrier (World Health Organization 2009). Residential ventilation systems and exhaust devices can affect indoor radon concentrations if they result in depressurization of the conditioned spaced relative to the outdoors or to the soil below the foundations or if they supply outdoor air directly.
