Window opening behaviour can have an important impact on residential energy use, especially in energy efficient dwellings. A few studies indicated that the window use may be a habitual behaviour, meaning that the behaviour is performed without conscious thought as a consequence of frequently repeating this action. Verbruggen et al. (2021a) developed an event-based residential occupant behaviour model (EROB) based on habits as present in Belgian dwellings, including a window opening model.

The global demand to improve the energy performance of buildings has led to greater air tightness and uncertainty in the ability of natural ventilation to maintain adequate indoor environmental quality. A monitoring campaign was carried out to evaluate the long-term indoor environmental quality across a year-long period in energy-efficient Irish dwellings.

A significant challenge lies in decarbonising existing residential stock to meet higher energy performance standards, necessitating increased energy retrofit activity. Despite the importance of energy retrofits, challenges arise in maintaining indoor environmental quality. While positive air quality and health benefits have been reported through targeted energy-retrofit activities, there are also numerous cases where indoor pollutant concentrations increase post-retrofit.
