How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The relationship between classroom ventilation and pupils’ performance was investigated in
primary schools in the United Kingdom. The concentration of carbon dioxide and other
parameters were monitored for three weeks in two selected classrooms in each school. A
direct air supply system through the windows was used to alter the ventilation rates in...
Research shows that poor indoor air quality (IAQ) in school buildings can cause a reduction in the students' performance assessed by short-term computer-based tests; whereas good air quality in classrooms can enhance children's concentration and also teachers' productivity. Investigation of air quality in classrooms helps us to characterise polluta...
Associations between classroom ventilation and pupils' performance were investigated in primary schools in the United Kingdom. The concentration of carbon dioxide and other parameters were monitored for three weeks in two selected classrooms in each school. A direct air supply system through the windows was used to alter the ventilation rates in th...
Ozone concentrations were measured concurrently inside a simulated aircraft cabin and in the airstream providing ventilation air to the cabin. Ozone decay rates were also measured after cessation of ozone injection into the supply airstream. By systematically varying the presence or absence of people, soiled T-shirts, aircraft seats and a used HEPA...
This paper examines correlations between indoor ozone concentrations and the emission rates of oxygenated compounds. It is based on re-analysis of data collected in an occupied, low-polluting office at two different ventilation rates (1 h-1 and 3 h-1) with and without common indoor sources, reporting that with sources present the measured total emi...
A re-analysis of two independent laboratory studies was made in which a total of 60 female subjects had been
exposed for several hours to 6 different air quality conditions in groups of 6 people at a time. The subjects
performed typical office tasks at their own pace during exposures. Measured carbon dioxide (CO2) concentrations
and outdoor air sup...
Unlabelled:
In groups of six, 30 female subjects were exposed for 4.8 h in a low-polluting office to each of two conditions--the presence or absence of 3-month-old personal computers (PCs). These PCs were placed behind a screen so that they were not visible to the subjects. Throughout the exposure the outdoor air supply was maintained at 10 l/s pe...
Air quality was studied in an office space classified as low-polluting and ventilated with outdoor air at a rate of 1 h−1. The pollution load in the space was changed by introducing or removing common building-related indoor pollution sources (linoleum, sealant and wooden shelves with books and paper documents) so that the space could no longer be...
The majority of climatized comfort spaces are located in office buildings. It is of particular importance to ensure an adequate heat and air quality comfort in such buildings as occupants usually spend their entire working day (8 hours) in their offices unlike in a theatre, restaurant or cinema. Furthermore, issues of comfort in office buildings mu...
