In the context of the emergence of new developments in residential smart ventilation and high demand for energy savings and providing acceptable Internal Air Quality (IAQ), this review is conducted with the aim of summarising the evidence of the benefits of implementing smart ventilation in residential homes. It focuses on ventilation strategies and their effectiveness, which consists of IAQ benefits, non-IAQ benefits (such as thermal comfort and noise), minimising energy consumption and minimising utility bills, and other advantages related to indoor environmental quality (IEQ).

This review seeks to answer two questions:

• What strategies have been investigated for smart ventilation systems in residential buildings?
• How effective are these smart ventilation strategies in improving IAQ and thermal comfort and minimising energy consumption?

This study is within the scope of IEA Energy in Buildings and Community (IEA EBC), Annex 86: “Energy Efficient Indoor Air Quality Management in Residential Buildings” focused on subtask 4 “Ensuring performance of smart ventilation”, which points to the necessity of reviewing existing smart ventilation strategies.
