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

(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

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

(author)Indoor air quality (IAQ) plays an important role in human health and well-being as people spend most of their time indoors. Among building materials, carpets covering high surface areas and having dense fibres have the potential to impact perceived IAQ. To explore the impact of carpets on perceived IAQ, it was studied whether low-emitting...journal article 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

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
