ATEOUE is a French working group created in June 1993 by the Ministry of Housing in order to harmonise and to facilitate the develop merit of tools concerning the improvement of building environmental quality (assessment methods, books of specifications, recommendations, etc. ... ). The methodological aspects play an important role in ATEQUE. ATEOUE is composed of the authorities concerned, and of 26 members representing all the categories of building professional actors (researchers, manufacturers, owners, designers, builders, consultants, service providers).
This paper describes the measured and calculated results of air humidity and profiles of tracer gas in a residential apartment in Taipei city, Taiwan. A complete multizone indoor air quality model was used to evaluate the test results. The concentration of C02 were employed to investigate the indoor pollutant transport. Also, the indoor air humidity was studied in order to evaluate the indoor moisture effects on human. The data from the measurements were used as simulation input data for the calculation of indoor air flow rates and pollutant concentrations.
Indoor Air Quality analysis needs at first an accurate prediction of indoor pollutant concentration levels. However, most of pollutant concentration prediction models consider the pollutants as passive elements. Our study introduces the more common gas-phase chemical reactions occurring in indoor spaces. We developed a model taking into account more than 20 different reactions influencing the concentration level prediction of NOx compounds, ozone, carbon monoxide and sulphur dioxide from the knowledge acquired in the field of tropospheric chemistry.
The paper describes a pilot-study set up to identify links between internal environmental quality and perceived well-being in a 1970's higher educational building housing the Mackintosh School of Architecture. The supposition is that such links may in turn inhibit/promote greater productivity. The study embraces a variety of working situations for staff and students and explores levels of satisfaction and dissatisfaction by means of questionnaire.
The management of environmental quality of school buildings has, for too long, been the overlooked half of the larger whole of the strategic educational planning process. This paper examines the changing role of environmental quality management from its traditional operationally-based role, to an expanded, more dynamic role in strategic educational planning activities at the local, site-based level. First, a brief review of the state of knowledge concerning the impact of environmental quality on the educational process is presented.
The purpose of this research is to give an overall prospect of the performance of 4 kinds of ventilation systems for dwellings using numerical simulation under various conditions. The total number of combinations of various parameters for the calculation is 174. Calculations for pollutant concentration, humidity and condensation, interior pressure and airflow rate, heat energy by ventilation, etc. are performed hourly through the heating season.
As everybody knows, today the air quality of an indoor environment may have several effectson our health; the beginning of serious breathing pathologies and of some forms of cancer,are with no doubt due to the presence of polluting and extremely noxious agents in the placeswe most frequently use.That's the reason why it is very important that indoor rooms are correctly aired also in ourhomes where, due to several incidental factors, the healthiness of the environment is stillguaranteed by the mere and discretionary operation of users of opening the windows.In considering the growing attenti
Dampness in residential buildings is detrimental to the health of the occupants and causes the growth of mold and decay in the fabric of the building materials. In Taiwan the average winter relative humidity is 80% and the average temperature is 15°C (59°F). It has been found that the average winter indoor moisture content in Taiwanese apartments can be higher than the outdoor content by as much as 15%. Although the main cause for the increased indoor humidity levels has not been identified, removing the moisture generated from shower baths can help reduce the humidity.
A number of approaches exist to evaluate building ventilation and indoor air quality. In some situations, the measurement and analysis of indoor carbon dioxide concentrations can be useful for understanding indoor air quality and ventilation. On the other hand, oversimplified descriptions of measurement procedures based on carbon dioxide have been presented, and there have been many instances in which indoor carbon dioxide concentration measurements have been misinterpreted and misunderstood.
