The Air Infiltration and Ventilation Centre (AIVC) together with the Eduardo Torroja Institute for Construction Science (CSIC) (IETcc-CSIC) and venticool organised a workshop entitled ‘Climate Change, Ventilation and Resilience’ held on 21-22 April 2026 in Madrid.
The 1 ½ day workshop provided an opportunity for Spanish researchers and professionals, as well as international experts, to present and discuss recent advances in relation to the challenges that climate change imposes on buildings, related to indoor environmental quality, ventilation, human health and sustainability.
This workshop was part of a series of annual international workshops organised by AIVC in collaboration with international research centres. These events also focus on local issues related to ventilation and infiltration as part of the knowledge generation process. At the Madrid workshop, the following topics were discussed:
- Ventilation systems and climate resilience
- Indoor Environmental health
- Assessment of IAQ in naturally ventilated dwellings
- IAQ remediation by smart materials and air cleaning
- Sustainable cooling in cities
- Personalised Environmental Control Systems (PECS)
- Case studies in relation to the workshop topics
