Quantitative analysis of indoor air quality under future climate scenarios: Projection till 2100’s for a Belgian case-study

The variations of Indoor Air Quality (IAQ) levels under the impacts of climate change are linked to the alterations of air pollutant emissions, both indoor and outdoor, and of the occupant's behavior. On the other hand, the retrofit action plans being applied on buildings to tackle the increasing extreme weather events and corresponding energy demands, result in more air-tight buildings with reduced air exchange rates and new HVAC technologies. In the current research project, the future state of IAQ in a Belgian case study is investigated quantitatively through the simulation process with CONTAM. The test house was a naturally ventilated studio flat (+2 exhaust fans) in the Wallonia region, south of Belgium. The new methodology developed allows for consistent results and can be used for IAQ predictions under climate change.
