The objective of this work is to evaluate the human thermal response in occupied spaces subjected to direct solar radiation. In this study, done in a full scale compartment equipped with an airconditioning system, a thermal-manikin (to simulate the human body posture), a multi-nodal human

The key principle of this work is that intermittent ventilation is equivalent to continuous ventilation if the pollutant exposure to an individual in the space is the same in both cases.

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.

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

Numerical prediction method in vehicle by using a thermoregulation model and CFD is described here. To achieve energy efficient car, not only improving efficiency of components like engineand compressor, but also reduction of cooling and heating load are very efficient. In this paper component to evaluate indoor thermal environment like automobile is described on recent our research results. All latest components are not combined yet perfectly. However, a thermoregulation model (65MN) combined with radiation exchange model and Computational Fluid Dynamics is mentioned.

Airflow characteristics in ventilated and air-conditioned spaces play an important role to attain comfort and hygiene conditions. This paper utilizes a 3D Computational Fluid Dynamics (CFD) model to assess the airflow characteristics in ventilated and air-conditioned archeological tombs of Egyptian Kings in the Valley of the Kings in Luxor, Egypt.

324 microenvironmental measurements were carried out with identical protocols on 81 elementary teachers working in 2 cities in eastern Finland. They allowed the comparison of the personal exposure to particles and microbes with the exposure assessed by stationary samplers in home and workplace.

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.

This paper presents the results of a study that explored if higher indoor minus outdoor CO2 concentrations were associated with increased student absence. The results of multivariate analyses are presented.

This study surveyed concentrations of airborne AP (alkyphenols) in indoor air and outdoor air in Tokyo. An analytical method has been developed using the gas chromatography/mass spectrometry-SIM.
