In the context of energy saving, new buildings are becoming more airtight and purpose-provided, often central mechanical ventilation is required to create and sustain a healthy indoor air quality (IAQ).
Nolwenn Hurel, Valérie Leprince, Marcus Lightfoot
Achieving energy-efficient dwellings has become a vital part of the global climate action plan to reduce energy usage and carbon emissions. Deep energy retrofits (DER) can help reduce residential energy use significantly.

The measurement of particulate matter (PM) in rooms has gained interest in the last decade.
Bart Cremers, Jan de Vries
In the residential sector, there are several indoor sources of pollutants related to activities such as cooking, cleaning and heating, besides those from occupants, building materials, finishing and furniture.
Daniela Mortari, Gaëlle Guyot, Nathan Mendes
Particles generated from cooking activities are the biggest contributor to the concentration of indoor particles in most homes, and they are not easily removed without natural or mechanical ventilation.
Shinhye Lee, Seongjun Park, Donghyun Rim, Donghwa Kang, MyoungSouk Yeo
Indoor air pollution can pose a serious threat to human health and can increase the risk of early mortality.
German Hernandez, Rafael Borge, Dan Blanchon, Terri-Ann Berry
Building energy behaviour and indoor environmental conditions have been changing due to different external events that have been taking place at global level from 2020, from the COVID pandemic (2020-2022) to the energy crisis (mainly from the war

The world has experienced the devastating nature of airborne transmitted diseases through the COVID-19 pandemic.
Alicia Murga, Kazuhide Ito, Makoto Tsubokura
The offer of air cleaners has increased significantly since the SARS-CoV-2 pandemic. However, it is not clear to what extent they can contribute to indoor air quality.
Hannelore Scheipers, Arnold Janssens, Jelle Laverge
The COVID-19 pandemic increased the awareness and importance of infectious pathogens as contaminant in the indoor air, especially for non-residential buildings with a high occupational density like schools.
Klaas De Jonge, Marianne Stranger, Sarah L. Paralovo, Maarten Spruyt, Borislav Lazarov, Tom Geens, Reinoud Cartuyvels, Koen Van den Driessche, Jelle Laverge, Arnold Janssens
Coughing is one of the most important respiratory activities for air transmitted pathogens. It is essential to understand the dispersion of exhaled particles when coughing to improve the prevention measure and reduce the cross-infection risk.
Chen Zhang, Peter V. Nielsen, Simon Madsen, Li Liu, Chunwen Xu, Zhengtao Ai
Some airborne pathogens can infect susceptible people over long distances in buildings when they are transported in small respiratory particles suspended in the air.

Accounting for inter- and intra-personal differences requires individual and cohort comfort models. For their development, emulators for thermal sensation of occupants are needed.
Dragos-Ioan Bogatu, Jun Shinoda, José Joaquín Aguilera, Bjarne W. Olesen, Futa Watanabe, Yosuke Kaneko, Ongun B. Kazanci
Most current environmental control systems installed in buildings aim to create a uniform IEQ, disregarding the large interpersonal and intrapersonal variability in occupants’ thermal, visual, acoustics & air quality requirements.
Douaa Al Assaad, Marco Perino, Dragos-Ioan Bogatu, Bjarne W. Olesen
Personalized Environmental Control Systems (PECS) have advantages of controlling the localized environment at occupants’ workstation by their preference instead of conditioning an entire room.
