Occupants use windows to control their thermal comfort and indoor air quality (IAQ). However, occupants often have to make a compromise between thermal, acoustic and visual comfort, IAQ and energy use for space conditioning. Moreover, they are not only looking for good indoor environmental quality, but also for their needs for security and privacy.

Ventilative cooling emerges to be a key element in the strategy to meet the cooling demand in buildings while cutting the CO2 emissions. Ventilative cooling also enhances thermal comfort and mitigates heat stress in buildings. Despite these benefits, the practical adoption of ventilative cooling remains limited among designers. There is still a need for design guidelines and assessment methods in standard weather conditions, extreme scenarios (such as heat waves) and urban environments.

Much progress has been made to improve the airtightness level of new buildings. Still, little is known about the durability of building airtightness, or the impact of degradation on airtightness. This report presents a comprehensive review of studies that deal with building airtightness durability. Regarding field measurement studies, the envelope airtightness seems to decrease during the first years after achievement and then stabilize. However, these variations are rarely explained. Key elements that may drive airtightness variations were identified.

In the context of energy use reduction, low energy buildings are becoming more widespread. This kind of construction requires a good envelope airtightness to prevent uncontrolled leakages of conditioned air leading to energy losses. As a result, more and more ventilation systems are installed to ensure a sufficient air change rate, to guarantee good indoor air quality and building durability while controlling energy losses.

In this webinar, we addressed the opportunities offered by smart ventilation strategies, which include a wide range of systems depending on the type of sensing parameters (CO2, humidity, occupancy, etc.), the type of sensing combinations, the type of installation (centralized/decentralized), the types of control algorithms, etc. We will also quantify their potential from and energy and IAQ point of view based on existing and newly developed assessment framework in the annex.
