LoginThe aim of this study was to test the following hypthesis : in schools, bacterial markers may be increased in indoor air because of the presence of children.Dust samples were collected from the school rooms when occupied but also when unoccupied d
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
The RAGENA model of radon takes into account all the parameters and processes affecting radon levels (in the source, its transport, its entry into a dwelling and its accumulation indoors).The model has been tested in a mediterranean house.
Usually only primary emissions from building products are measured. That study takes into account potential secondary emissions due to oxidation with ozone.
Accurate mathematical models of airborne infection are needed to estimate the risk from secondary transmission of biological warfare agents.
A questionnaire study (on ventilation, surface materials, heating and cooling) was performed on 3562 employees working in 32 buildings without previously known indoor air problems.The associations between symptom prevalence and building characteri
This paper is a presentation of a methodology for developing responses to sudden releases of toxic pollutants in buildings.
This paper intends to resolve the spatial and temporal variation of VOC concentrations in apartments.
This paper proposes a space zone model for the calculation of all the airflow parameters based on tracer gas measurements, including flow rates of outdoor air, VAV supply.
One of the major means of air diffusion for air conditioning equipment is the displacement ventilation.
The changes in occurrence and the distribution of airborne fungi when they are transported in the airstream from the outdoor air to the indoor air are not well-known.
Carbon dioxide concentration, indoor air temperature and relative air humidity are studied in 7 schools with natural ventilation systems, during 58 days on one year. The results show that the level of 1500 ppm of CO2 is exceeded in 39 days.
This article defines a new air-exchange efficiency that takes into account the occupancy in each zone.. Cases studies are then described and show that the new efficiency can better evaluate the ventilation effect of the room.
In this study, associations between concentration levels of airborne particles and fungi were examined in 14 houses in Brisbane.
This article is a study of the air quality at a bus terminal. Presence and concentration of indoor air quality indices were determined by field surveys and sampling.
The aim of this study is to compare the exposure to environmental tobacco smoke (ETS) of people in smoking and nonsmoking dining room.
For that study, a classroom was modelled and a comparison of the performances of a specific hybrid ventilation system with a traditional mechanical system in terms of thermal comfort, indoor air quality concerning the CO2 concentration and energy
Generally the calculation methods ignore the interaction of air leakage and heat conduction in building envelope.
The authors have developed a tool called SimSPARK able to automatically build dynamic zonal simulations of a building zone. In that study, SimSPARK architecture is described in details along with the current zonal model library.
There is a growing need for more complex control of ventilation systems to satisfy energy and environmental issues.
The validation and development of turbulence models are still important issues related to Computational Fluid Dynamics for ventilation purposes. The present work continues the work initiated by (Voigt, 2002).
