Through a simulation study, thermal comfort of occupants and indoor air relative humidity in an office have been assessed. The authors observed that it is not always desirable to have cooler with higher saturation efficiency for applications where low indoor air relative humidity is of primary concern, in that case an ordinary evaporative cooler can be used that allows slightly higher air change rate within the occupied space.

This paper gives the description of two ways of modelling an office building. Measurements made in a case building over a year are used for the calibration of two simulation models : one is a full-building model and the other one simulates a single zone , it takes into account only the adjacent rooms.The aim of the study is to find if the single-zone modelling approach is appropriate for energy use estimations. Results are presented.

The cold air distribution system using ice thermal storage creates easily a low humidity environment whereas the system using a fluctuating breeze creates the feeling of coolness by actively generating airflow (an intermittent breeze) over the human body under a low humidity environment. That second system keeps the room temperatrue at a higher level, allowing energy savings in a comfortable environment. A model of a thermal sensation sensor was developed and the results obtained are presented.

5 comfort studies were conducted in hot humid regions Japan (for outdoor comfort), Thailand, Singapore and Indonisia (for indoor comfort) : thermal sensations of human subjects were recorded under different conditions of temperature, air speed and humidity. Formulas developed on the basis of the experimental data are presented in this paper. It also focuses on the residual effect of humidity in each of the studies.

The refurbishment of public buildings in Greece gives the opportunity to reconsider the design parameters of out of date, or deficiently designed buildings on the one hand and to proceed with retroffitting actions including indoor environmental quality parameters.. In this paper, aspects of thermal comfort and indoor contaminant control during the refurbishment of specific buildings are presented.

As part of a programme of research investigating thermal comfort on underground trains in London, BRE designed and constructed an experimental facility to be as realistic as possible for "passenger " subjects. Tests were carried out to investigate passengers' thermal comfort in realistic summer conditions. 574 subjects completed questionnaires , the data were included in the analysis, a model was derived to predict passenger response. As expected , temperature was the most important parameter influencing passenger comfort.

For that study , a survey was conducted within a period of one-year by delivering questionnaires to six hundred students in a chinese universtiy (Hunan Province), measurement on the spot and statistical analyses of collected data were made. Their conclusions are presented.

This paper reports on the relationship between dryness of the eyes and the presence of airflow around the eyes..The results of a CFD analysis show that a rising airflow around the body forms a coating over the surface of the face. That boundary layer disappears on the face when there is a horizontal room airflow which comes towards the face. Then measurement of the mass transfer coefficient of water on the human face and eye is made.

Physical IAQ parameters were sampled and results plotted in an IAQ study of a high-rise building in Hong Kong. Chemical samples were obtained and results indicated acceptable IAQ based on local and international guidelines. Common complaints of poor IAQ because of "stuffy air" and "odors" from unidentified sources have been recorded ever since initial occupancy. Source of odor was traced , it came from a poorly designed AHU drain-traps. A follow-up survey was performed. Results are compared and reported.
