New methods were used for that study, to evaluate the factors affecting productivity. Parameters of fatigue were investigated along with task performance.

That study was performed in a call center. During nine consecutive weeks, temperature and outdoor air supply rate were combined and introduced to the occupants in a blind intervention approach.Those 2 variables had significant interaction effects on the workers' talk time.

This paper sums up the knowledge on good and bad effects of ventilation on health and other human responses. The focus is on working environment in offices and residential buildings.

This paper summarizes a series of 10 experiments made in offices in order to quantify the effects of indoor environmental factors on performance. It is possible that those effects of poor indoor air quality, have caused the reduction of performance in office work.
This series is extended to carry out field experiments on air quality in schools.

This paper describes how the pollution loads in non-industrial buildings can be quantified by using the olf unit. It also sums up the existing data on the measured sensory pollution loads. Their use seems the most suitable approach for the prediction of ventilation rates required for an acceptable indoor air quality.

This paper presents the results of a field experiment made on 30 female office workers : they were investigated on their perception of environmental conditions and the intensity of the Sick Building Symptoms if any, at 3 levels of temperature and humidity, and 2 levels of ventilation rate.
The conclusion is that working conditions improved when subjects worked at slightly lower levels of air temperature and humidity.

The aim of this paper is to identify the link between indoor environmental factors and asthma or allergic symptoms among small children and their parents. That four-phases Swedish study will be lasting from 2000 until 2008 : First step : an epidemiological cross-sectional questionnaire on housing and health involving 14,077 preschool children (2000).Second step : a nested case-control study including 198 children with symptoms and 202 healthy controls.

Main environmental studies are today, outdoor air quality, but not indoor air quality though there is mounting evidence that exposure to IAQ is the cause of excessive morbidity and mortality.Research within the areas of developing countries has had a low priority during the last half century compared with research on ambient air or industrial air.

In that study, two air supply devices were investigated in order to simulate the characteristic of natural wind. The paper demontrates that the simulated natural air movement had an acceptability, for the subjects exposed, higher than the artificial air movement. With simulated natural air movement comfort may improve with energy saving in warm climates.

This paper, on the basis of existing literature, sums up the factors that influence the human perception of air movement and it also tries to specify in general terms when air movement is desirable and when it is not.
