When making homes more sustainable, the emphasis is on scaling up to achieve the climate and energy objectives. Little attention is paid to air quality in homes, despite the fact that an estimated 98% of the Dutch homes do not meet the WHO's 2021 annual guideline value for PM2.5. Tackling sustainability and the indoor environment hand in hand is therefore important.

Heatwaves are extreme events that will become more frequent and intense with climate change. Maintaining a comfortable and healthy indoor environment becomes crucial during these periods. The occupants are not just passive individuals who undergo the evolution of their environment. They can act to ensure their thermal comfort, in particular by opening or closing windows in summer.
