Hobeika, N. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)The corona pandemic accelerated a lot of studies about aerosol dispersion and different aerosol-generating tasks ranging in intensity from sneezing to breathing. Both measurements and numerical simulations were used to understand the behaviour of aerosols. For numerical simulations, Computational Fluid Dynamic (CFD) simulations were used;...conference paper 2023

Hamida, A.B. (author), Eijkelenboom, A.M. (author), Bluyssen, P.M. (author)Students are exposed to various environmental stimuli at their home study places. However, different students have different preferences in terms of indoor environmental quality (IEQ) aspects and psychosocial aspects of these places. A previous study on students' preferences of their study places resulted in nine profiles based on their IEQ and...conference paper 2023

Bluyssen, P.M. (author)Indoor environmental quality is still described with quantitative dose-related indicators, expressed in number and/or ranges of numbers for each of the factors (indoor air, lighting, acoustics, and thermal aspects). Interactions of stressors and effects at and between human and environment level are ignored. Individual differences in needs and...conference paper 2023

Ding, Er (author), Zhang, D. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)During the COVID-19 pandemic, the importance of ventilation for ensuring occupants’ health was widely stressed, especially for densely occupied places such as schools (Ding et al, 2022). Correspondingly, new protocols of ventilation were implemented in school buildings among many countries and regions. In the Netherlands, school classrooms were...conference paper 2023

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

Ortiz, Marco A. (author), Bluyssen, P.M. (author)Due to the SARS-CoV-2 pandemic, several strategies have been proposed to reduce its transmission, from social distancing, regularly disinfecting items and hands, and wearing barrier masks. Guidelines and standardization propose certain tests for the filtration of the masks, or visual inspections to check the materials. However, no standards...conference paper 2021
