A 2x2 balanced experiment was carried out in an air-conditioned call center in the Tropics using a blind intervention approach to study the combined effects of temperature and outdoor air supply rate. Twenty-six permanent call center operators participated in the nine-week study. Intensity of headache symptom was significantly reduced with increased outdoor air supply rate at 24.5C (P<0.03). Similar observation at P<0.04 was observed for a principal component (neurobehavioral symptoms and self-assessed productivity) derived from a set of self evaluated symptoms.

This paper sums up a longitudinal study carried out on a group of students and teachers in a remediated moisture-damaged school. Registration of subjective data (questionnaires) and objective data (nasal histamine reactivity) has been made. Results and discussion are presented.

The thermal environment and air quality in buildings affects occupants’ health, comfort and performance. The heating, ventilating and air-conditioning (HVAC) of buildings today is designed to provide a uniform room environment. However, large individual d

A recent survey study suggested that elderly people’s lifestyle and building + dwellings factors exposed them to an uncomfortable and poor environment regarding indoor air quality. In order to confirm the qualitative statements of this study, measurements

After the moisture damage repairs, a health symptom questionnaire study was repeated 1 year, 3 years and 5 years on 245 upper secondary and high school students. The data were analyzed. The results indicate that no new cases of symptomatic students occured : in that sense the repairs succeeded.

In this swedish report, an inventory and a multidisciplinary review (EUROWORKS) of the scientific literature about networks on indoor environmental quality and health is made. That work was performed during 2001 and was supported by the European Commission.

This study aims to assess the relationship between building and allergen exposure, and between dwellings and pollutants enhancing allergen response. Kind of allergens and pollutants are described with their sources, and measured levels. The authors conclude that the role of the medical corporation in the future will be very important for the improvement of the indoor air quality.

The author describes the most important indoor air related health determinants and a table gives information on the source characterisation of health determinants indoors, their control method along with examples of actions that could be taken by national level bodies or societies.

This paper is a review of data collected in European dwellings on particulate matter (PM), nitrogen dioxide (NO2), carbon dioxide (CO2), carbon monoxide (CO), volatile organic compounds (VOCs), formaldehyde, dampness/mould and dust mites at home. Related health effects are summarized in this review too, along with some results not yet published from two Italian indoor air studies.

This paper emphasizes on the role of hydroxyl radicals in indoor processes, on chemical reactions occurring on indoor surfaces, and the impact of products of indoor chemistry on building occupants. The products of indoor chemistry can impact comfort and health, but the importance of those effects and the frequency of their occurrence remains to be elucidated.
