During perception with our senses, interactions of different environmental stressors at brain level might occur. Previous studies have shown cross-modal effects between sound and odour. To test these effects of different sounds and levels of sounds on the perception of sound, tem ...
Research has shown that even though the indoor environmental conditions seem to comply with current standards and 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 guide ...
De via de lucht overgedragen infectieuze respiratoire deeltjes (IRDs), ook wel aerosolen genoemd, zijn de primaire route van overdracht voor respiratoire infectieuze ziektes zoals COVID-19 [1]. Klaslokalen hebben een verhoogd risico op besmetting vanwege de lange en hoge bezettin ...
As mandatory masking and social distancing measures decrease post-COVID-19, the risk of airborne pathogen transmission in crowded indoor spaces remains a significant public health concern. The pandemic highlighted the critical role of indoor air quality and ventilation in mitigat ...
To investigate the feasibility of using mobile air cleaners (MACs) in school classrooms for reducing respiratory aerosols, a test on aerosol removal of seven different types of MACs was conducted in a university classroom, for the optimal condition determined by a prior experimen ...

Mandating indoor air quality for public buildings

If some countries lead by example, standards may increasingly become normalized

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) perf ...

Wat je moet weten over klimaatinstallaties

Het hoe en waarom van klimaatinstallaties in een notendop

Airconditioning heeft een negatief imago: het zou ons minder tolerant maken voor temperatuurveranderingen; produceert achtergrondlawaai; zorgt voor tocht; kan de lucht verontreinigen; is moeilijk te bedienen; heeft onderhoud nodig; en gebruikt veel energie. Het is echter in princ ...

Thermal and indoor air quality in dwellings in Europe during summer

A literature review on findings from empirical studies

Changing outdoor conditions, i.e. higher outdoor air temperature, higher occurrence of heatwaves and outdoor air pollution, increase the risk of overheating and accumulation of air pollution in homes. Previous studies showed that high indoor air temperatures and air pollution aff ...
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 r ...
University students spend a considerable time at study places. The acoustical quality of these study places is one of the indoor environmental qualities (IEQ) that can have an impact on student’s health, comfort, and performance. The indoor soundscape approach has been introduced ...
Previous studies have shown that sound influences students both physiologically and perceptually. However, most of these studies focussed on the effects of sounds at group-level, ignoring individual differences. Therefore, we investigated which indicators can be used to identify ...
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 abs ...
In the realm of environmental, social, and governance (ESG) reporting, the spotlight typically focuses on factors like carbon emissions, social responsibility, and corporate governance. [...]
Mobile air cleaners (MACs) have been proposed as a supplementary solution to combat the spread of respiratory aerosols in school classrooms. To determine which, where and how to use MACs, seven small- and medium-sized MACs were selected and assessed for different settings and con ...
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 data ...

Wat je moet weten over binnenlucht

Een eenvoudige gids om jezelf te leren je binnenmilieu te verbeteren

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 t ...
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 stude ...

Ventilation and thermal conditions in secondary schools in the Netherlands

Effects of COVID-19 pandemic control and prevention measures

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 str ...

Coronavirus Disease 2019 and Airborne Transmission

Science Rejected, Lives Lost. Can Society Do Better?

This is an account that should be heard of an important struggle: the struggle of a large group of experts who came together at the beginning of the COVID-19 pandemic to warn the world about the risk of airborne transmission and the consequences of ignoring it. We alerted the Wor ...
