To give some rules to the construction industry, a new standard on the ventilation was issued in Portugal (NP 1037-1:2002). This standard deals with natural ventilation. Some researchs are being carried out to assess impact of the natural ventilation on indoor environment.
This study aims to assess the relationship between building and allergen exposure, and between dwellings and pollutants enhancing allergen response. Kind of allergens and pollutants are described with their sources, and measured levels. The authors conclude that the role of the medical corporation in the future will be very important for the improvement of the indoor air quality.
The author describes the most important indoor air related health determinants and a table gives information on the source characterisation of health determinants indoors, their control method along with examples of actions that could be taken by national level bodies or societies.
ETS has been recognized as a toxic agent in 1986 that could cause lung cancer, effect the pulmonary function, later on, other studies and surveys found association between ETS and asthma, with risk of coronary heart disease. This paper is a review of those different studies.
This paper is a review of data collected in European dwellings on particulate matter (PM), nitrogen dioxide (NO2), carbon dioxide (CO2), carbon monoxide (CO), volatile organic compounds (VOCs), formaldehyde, dampness/mould and dust mites at home. Related health effects are summarized in this review too, along with some results not yet published from two Italian indoor air studies.
For that study, 200 children in Manchester were recruited to assess their asthma status, their indoor environment was analyzed. Levels of a variety of indoor agents, reported as important factors in the development or the exacerbation of respiratory troubles were examined. Results are presented.
The aim of that study is to produce guidance in adequate ventilation in new domestic buildings. The paper gives a description of the development and application of a method for measuring the mean ventilation rate in occupied homes with the measurement of indoor air pollutants. Results are presented.
This paper is a review of almost two decades work on pollution sources in ventilation systems. There is a special emphasis on ventilation filters with reference to the work of other researchers. A view into future research and developement with engineering solutions is also presented.
This paper emphasizes on the role of hydroxyl radicals in indoor processes, on chemical reactions occurring on indoor surfaces, and the impact of products of indoor chemistry on building occupants. The products of indoor chemistry can impact comfort and health, but the importance of those effects and the frequency of their occurrence remains to be elucidated.
Individual differences in preferred air temperature may be as great as 10°C, and preferences for air movement may differ more than four times for the occupants. Personalized ventilation can improve occupants' comfort in so far as thermal discomfort is oft
