Hamida, A.B. (author), Zhang, D. (author), Ortiz, Marco A. (author), Bluyssen, P.M. (author)Sounds (e.g., human activity, nature, building systems) are one of the indoor environmental stimuli that may have positive and/or negative effects on students’ well-being and performance in educational buildings. Students in educational buildings have individual acoustical preferences and needs as portrayed by occupant-related indicators, for...journal article 2023

Bluyssen, P.M. (author)Since the first outbreaks of COVID-19, research has focused on how to minimize SARS-CoV-2 transmission indoors. SARS-CoV-2 has three identified transmission routes: (1) direct transmission of virus-carrying droplets between people in close proximity, by coughing, sneezing or talking; (2) indirect transmission via deposited, or transmitted,...book chapter 2022

Ortiz, Marco A. (author), Bluyssen, P.M. (author)Building retrofitted to be resilient in the face of future climates may present risks for the health and comfort of the occupants, due to the indoor environmental quality changes involved under current building practices. This chapter is a literature review of recent peer-reviewed papers from a variety of fields identifying such potential...book chapter 2022

Bluyssen, P.M. (author)Research has shown that, even though the indoor environmental conditions seem to comply with current guidelines and those conditions seem ‘comfortable’ enough, staying indoors is not good for our health. Reasons for this discrepancy might be the fact that these guidelines are based on single-dose response relationships to prevent negative...conference paper 2022

Hamida, A.B. (author), Zhang, D. (author), Ortiz, Marco A. (author), Bluyssen, P.M. (author)During the COVID-19 outbreak, university courses were shifted online and students spent the majority of their time inside their homes. However, staying indoors can affect students’ health due to the exposure to several environmental stressors, such as background noise, and/or inefficient ventilation, and/or insufficient lighting. Previous...conference paper 2022

Ortiz, Marco A. (author), Bluyssen, P.M. (author)The worldwide spread of the Coronavirus disease 2019 forced governments to enact different measures to mitigate the infections. Employers and workers had to adjust by shifting a substantial number of jobs to a “work from home” configuration (WFH). On average, people used to spend around 90% of their time indoors, however, this number may have...conference paper 2022

Zhang, D. (author), Ding, Er (author), Bluyssen, P.M. (author)Several recent studies have demonstrated that ventilation plays an important role in the transmission of SARS-CoV-2 (the coronavirus that causes COVID-19) in public buildings, such as schools. However, there are no clear rules on how to assess the ventilation performance in classrooms, especially during a pandemic. Therefore, the main objective...conference paper 2022

Liu, Y.L. (author), Ortiz, Marco A. (author), Zhang, D. (author), Bluyssen, P.M. (author)The airborne transmission of SARS-CoV-2 in educational buildings has raised concerns during the current COVID-19 pandemic. In this study, a portable fog generator system was designed and assembled to visualise the airflow pattern of exhaled droplets in a classroom. The system consists of five components: medium, fog generator, buffer, pump, and...conference paper 2022

Ding, Er (author), Zhang, D. (author), Bluyssen, P.M. (author)Airborne transmission of small respiratory droplets (i.e., aerosols) is one of the dominant transmission routes of pathogens of several contagious respiratory diseases, which mainly takes place between occupants when sharing indoor spaces. The important role of ventilation in airborne infection control has been extensively discussed in...review 2022

(author)Abstract The question of whether SARS-CoV-2 is mainly transmitted by droplets or aerosols has been highly controversial. We sought to explain this controversy through a historical analysis of transmission research in other diseases. For most of human history, the dominant paradigm was that many diseases were carried by the air, often over long...journal article 2022

Zhang, D. (author), Bluyssen, P.M. (author)Airborne transmission has been confirmed as one of three principal ways of SARS-CoV-2 transmission. To reduce the transmission of SARS-CoV-2 indoors, understanding the distribution of respiratory droplets (or aerosols) present in human breath seems therefore important. To study whether the CO2 concentration can be used as a proxy for the number...journal article 2022
