LoginThis review examines the available information relating to the ingress of external pollutants into naturally ventilated buildings.
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.
This paper examines three different ventilation strategies aimed at reducing the indoor concentration of traffic pollutants by ventilation control.
With sensor-based demand-controlled ventilation ( SBDCV), the rate of ventilation is modulated over time based on the signals from indoor air pollutant or occupancy sensors.
A C02 concentration of more than 1000 ppm has been monitored in Taiwanese bedrooms during sleeping hours in the wintertime. The high indoor C02 levels were caused by poor ventilation due to insufficient ventilation rates.
Recent concern has centered on "sick buildings" in which there has been an unusually high percentage of health complaints by the building's occupants.
Statistics indicate that flying is the safest way to travet, but a trip on a ptane coutd be more hazardous to your health than you might imagine. Carolynne Dear reports.
Ventilation system designers may be guilty of professional negligence by working with inaccurate noise data and, even worse, they may be unwittingly causing Sick Building Syndrome. Ewen Rose reports
Numerous ground-coupled air systems have been constructed in combination with heat recovery units in mechanically ventilated buildings in Switzerland.
Sensory responses to clean air and air polluted by five building materials under different combinations of temperature and humidity in the ranges 18-28°C and 30-70%RH were studied in the laboratory.
Vertical concentration profiles for various size fractions of airborne particulate matter have been measured in a nonsmoking indoor environment used mainly as a meeting point during coffee break (11.00 a.m.) and tea time (4.00 p.m.).
