For that study indoor and outdoor temperatures were recorded (respectively every 20 s and 1 minute) for 10 apartments houses in Japan during summer-autumn with the intention to investigate the relationships between ratios of air conditioner use and window opening. The method and results are presented.

In this paper the results of the "Integral Design Methodologyy" workshop for sustainable comfort systems are presented. The objective was to reduce failure costs and to improve design quality for ventilation concepts.

The ventilation of two newly built school buildings in Finland are compared in that study, one of the experimental building is equipped with fan assisted natural ventilation and the other one with mechanical supply and exhaust ventilation system with heat recovery. The results are presented.

The objective of that study is to analyze the influence of outdoor air and sypply air system on particle levels, along with the effect of indoor sources on them. Particle measurements were carried out in three different buildings : a school, an office, and a single-family house in Northern Finland.

For that study two different rectangular test chambers of different size(9.37 m3 and 0.14 m3) were realised, in order to analyze the behaviour of fine particles deposition in rooms and to show the influence of airflow velocity on it.. Several experimental measurement results are presented

This objective of that study is to clarify the numbers and species of bacteria and fungi present on the surfaces of air filters at various temperatures and relative humidity. The comparison of different types of adherent bacteria and fungi in the surface between enzyme and control filters is made too.

Field measurements have been carried in commercial kitchen to assess the performance of ventilated ceiling system, hanging the combination of ventilation rate and operating electrical appliances in order to find the best control method to realize energy consumption.

In Korea, "Ondol" a radiant heating system is widely used but it is not satisfying with ventilation, so this study aims at developing a ventilation system to improve thermal environment and ventilation rates.

Typical modes of air distribution such as ceiling supply and under-floor supply systemshave been investigated by using a breathing thermal manikin in a field environmental chamber. The two systems are compared , conclusions and recommendations are presented.

The objective of this study is to evaluate the effectiveness of (UFAD) system in controlling thermal comfort and indoor air quality in office building. In that aim environmental parameters have been measured, concentrations levels of pollutants have been monitored, the air exchange rate and percentage of oudoor air have been studied, and the results compared with recommended standards.
