Noorian Najafabadi, S.A. (author), Ding, Er (author), Hobeika, N. (author), Bluyssen, P.M. (author)Indoor air quality (IAQ) is an important aspect of maintaining human health and well-being, particularly since people spend most of their time indoors. Carpets, with their large surface area and dense fibre piles, have the potential to significantly impact IAQ by emitting and absorbing volatile organic compounds (VOC) from building materials and...journal article 2024

Hamida, A.B. (author), Eijkelenboom, A.M. (author), Bluyssen, P.M. (author)Understanding students' preferences of their study place, in particular acoustical and psychosocial preferences, is important to students' health and comfort. This study aimed to identify clusters of students with similar acoustical and psychosocial preferences, and to identify reasons for certain preferences of students in each cluster. A mixed...journal article 2024

(author), Buonanno, Giorgio (author), Cao, Junji (author), Dancer, Stephanie J. (author)People living in urban and industrialized societies, which are expanding globally, spend more than 90% of their time in the indoor environment, breathing indoor air (IA). Despite decades of research and advocacy, most countries do not have legislated indoor air quality (IAQ) performance standards for public spaces that address concentration...journal article 2024

(author), Linde, Kimberly J. (author), Wouters, Inge M. (author), Bluyssen, P.M. (author)During the COVID-19 pandemic, the importance of ventilation was widely stressed and new protocols of ventilation were implemented in school buildings worldwide. In the Netherlands, schools were recommended to keep the windows and doors open, and after a national lockdown more stringent measures such as reduction of occupancy were introduced. In...journal article 2023

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

Hamida, A.B. (author), Eijkelenboom, A.M. (author), Bluyssen, P.M. (author)Research has shown that students differ in their preferences of indoor environmental quality (IEQ) and psychosocial aspects of their study places. Since previous studies have mainly focused on identifying these preferences rather than investigating the different profiles of students, this study aimed at profiling students based on their IEQ and...journal article 2023

Hobeika, N. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)The COVID-19 pandemic highlighted the importance of indoor air quality (IAQ) and ventilation, which researchers have been warning about for years. During the pandemic, researchers studied several indicators using different approaches to assess IAQ and diverse ventilation systems in indoor spaces. To provide an overview of these indicators and...review 2023

Overtoom, M.E. (author), Elsinga, M.G. (author), Bluyssen, P.M. (author)A significant number of young people live in temporary homes, which are designed to fulfil basic needs and provide space for normal activities. However, it is unclear what those basic activities are. Moreover, the indoor environmental quality is often left out of the meaning of home, although activities and objects can affect its experienced...journal article 2023

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

Hobeika, N. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)The corona pandemic underlined a lack of Indoor Air Quality (IAQ) and<br/>ventilation. Consequently, to limit the spread of the virus, researchers explored several indicators that, through different approaches, assess IAQ and ventilation performance in indoor spaces. This paper gives an overview of those indicators and assessment methods used to...abstract 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...abstract 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...abstract 2023

Bluyssen, P.M. (author), Zhang, D. (author), Ortiz, Marco A. (author)Recent studies have shown that both personal and building-related factors may affect the health and comfort of occupants in their homes. It is also known that people differ in their needs and can therefore respond differently to these stressors. Therefore, based on the large database from the survey conducted yearly from 2016 to 2020 among the...journal article 2023
