This study is concerned with the impact of indoor environment on the local National health in airconditioned spaces. The present study is carried out in different applications in Egypt. Two differentmethods are utilized in the present study. An experimental measurement program and comprehensive survey are carried out for some air conditioned applications. The numerical methodsare also utilized to simulate applications that represent the effect of indoor environment onoccupancy health using different indoor air quality indices.

To evaluate effect of indoor environment quality on productivity, the changes in cerebral bloodoxygenation by near infrared spectroscopy was examined. In this study, relationship between the changes in cerebral blood oxygenation and difficulty level of task was evaluated by subjective experiments. Four tasks were given to the subjects: single-digit addition, double-digit multiplication, triple-digit addition, and triple-digit multiplication. It was evaluated that the more difficult task types to solve, the more oxygenated hemoglobin and total hemoglobin concentration were needed.

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.
