The aim of that study that lasted 5 years was to assess the effect of repairs made to moisture-damaged school buildings on the students' health. With repeated questionnaires it was possible to compare the occurrences of symptoms before and after the repairs in school.
This paper presents a study on the variability in chemical exposures or individuals that are working in eight different office buildings in Sweden. The variability among buildings and the variability among individuals has been evaluated for a selected number of detected VOCs along with the ratio between the two variances.
The aim of that study was to determine whether there was a quantifiable difference in biocontaminant levels between one school with a carpeted floor and another school with hard surface floor. During one year, air and floor dust samples were collected and analyzed. The results suggest that floor covering is not the major contributor to airborne levels of biocontaminants in nonproblem schools.
This study quantified the daily average concentrations of respirable particulates in rural homes from three Indian districts. Thanks to this data a model is being developed to predict quantitative categories of population exposure based on survey information on housing and fuel characteristics. A better estimation of health risks will be possible.
This paper reports the distribution of VOC exposures, and explores the statistical associations between concentrations and common sources and modifiers of exposure, and examines the associations between personal, indoor, and outdoor exposure levels in children.
Advantages and drawbacks of a Displacement Ventilation system are presented in this paper, in comparison with the traditional "mixing" ventilation cooling systems.
The search for top quality is the requirement of the professionals of "hygienisation". A description of desinfection with its methodology applied to ducts is presented : dust removal, cleaning of the surfaces before their disinfection.
In this paper, the author presents what could be done to improve the poor indoor air quality in some schools :- A demand for accountability from school systems about maintenance procedures such as roof-leak repair, classroom ventilation and air-conditioning, presence and care of carpeting etc.- A promotion of a responsible and adequate funding for the maintenance of public facilities- The most important activity is a good, basic, responsive and adequately funded building maintenance.
In so far as natural ventilation system is totally dependent on local weather conditions and building facade elements, housing ventilation cannot be permanently guaranteed. This paper offers a computational flow simulation (CFD) which can be used to analyze housing ventilation under different buildings and weather conditions.
The aim of this paper is to give an overview of the work carried out during three years with URBVENT project and to present its main issues: - to provide methodologies and accompanying software tools to assess the potential and feasibility of natural ventilation - to design optimal openings for efficient naturally ventilated buildings.The different partners of this project are: five European University laboratories, two technical centers and one industrial company.
