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.

The aim of that study was to test the impact of cleaning on indoor environement quality. Surface dust measurements were made on samples taken from office rooms before and after cleaning during the heating period of the buildings. Before the sampling, the occupants completed a questionnaire survey. The data were analyzed then discussed.

This study shows the possiblity of improving indoor air quality thanks to underfloor ventilation systems. The top-return configuration and the floor-return one are tested and compared to a traditional ceililng based mixing system.

The second part of the VIP Indoor air pollutants concerns the sources of pollutants and effective measures to control them or to make their impact on occupants less severe.
