A study was performed in 6 elementary schools in Japan,and measurements were made on temperature in classrooms and corridors, outdoor temperature, CO2 concentration and closing or opening of windows and doors.

A food odor spread is one of the air quality problems in high rise residential buildings in Korea. The food odor is mainly produced during the cooking of food. The food odor is generated in the limited spaces like in the kitchenand at a table. The ventilation systems in the buildingsdesigned to control air quality actually make the food odor spread more widely. To control the food odor spread, another types of ventilation systems are needed.In the paper, the kitchen ventilation system to prevent the food odor spread is introduced.

The energy performances of a summer air-conditioningsystem with variable airflow destined fora sole air-conditioned open-space environment which hosts a call-centre are presented. With a simple plant configuration,implementing an opportune control strategy aimed at the simultaneous satisfaction of sensitive and latent loads, the principle energy indexes and thermal comfort with reference to a location with a typical Mediterraneanclimate (Cosenza, Southern Italy) were identified.

This paper evaluates current situation of the university building which is considered oriented in the wrong direction,in the campus area of Izmir Institute of Technologyin Izmir, Turkey. The building, which houses the Faculty offices, is used by the Faculty of Architecture. Experience has indicated that cooling loads of the buildingare quite high, as it is oriented with the main design decision of facing the sea panorama along the long axis, lying in north-southerly direction, 11 from north to east.

More than 8.000 homes have been built to the Passivhausstandard in central Europe. The success of Passivhaus is due in large measure to it being a well defined product, understood by the developer, architect and future owner. However the Passivhaus standard was born to respond to the requirements of a relatively cold region. The EIE funded Passive-On project has examinedwhat elements of the standard could be useful in promoting the diffusion of low energy house design in southern Europe.

In Heerlen, the Netherlands, warm and cold water volumesfrom abandoned mines will be used for heating and cooling of buildings, based on a low exergy energy infrastructure. The combination of low temperature heating and cooling emission systems, advanced ventilationtechnologies and integrated design of buildings and building services provide an excellent thermal comfortand improved indoor air quality during 365 days/year, combined with a CO2 reduction of 50% in comparisonwith a traditional solution.

In the present study the relation between the wind speed and the air temperature during the summer period over the greater area of Athens is examined. Specifically, the hourly data of the air temperatures, recorded by 27 stations,were studied for the months of June, July, August and September during the period from 1996 until 1998, in relation to the corresponding mean hourly values of the wind speed which were measured by the National Observatory of Athens. As a result, a low increasing rate of air temperature in correlation to the wind speed exists during the day and night, time period.

The wind-induced natural ventilation of atrium buildingswith two roof openings has been investigated using computational fluid dynamics (CFD) techniques.

This study aims at examining the reduction of indoor air contaminants by plants placed in an indoor space.Field measurements were performed using Aglaonema brevispathum, which were verified as air-purifying plants by NASA.Two conditions for the amount of plant was used in two separate rooms whose dimensions are identical.

Field survey on indoor air quality was conducted during winter season, in an elementary school at Kagoshima city. Asthe windows had been closed because of avoidingthe cold outdoor airIn thewinter,CO2 concen- trationsunder pupilsstaying in the classroom wereover1500 ppmat the end of the lesson. When the windows of the corridor facing outside had been open, the CO2 concentrations in corridor were close to the outdoor CO2 concentrations. It was found that the ventilation during the break could play an important role in CO2 concentrations during the next lesson.
