LoginTwo out of fourteen workers in a clerical office suffered bronchial problems. An investigation found gross contamination with Penicillium mould of forced-air heater-cooler units which had not been properly maintained.
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.
Describes monitoring of an office building where sick building syndrome symptoms had been reported. Data were taken under two different ventilation rates.
Human exposure to nitrogen dioxide can have adverse health effects.
Compares the air change rates measured using the decay method with several different tracer gases. Tracer gas measurements were conducted in a tightly sealed room where constant air leakage rates were maintained using an exhaust fan.
States that windows and doors are the biggest source of energy loss in a house. This happens by air infiltration, conduction and radiation.
Uses a two-region model to predict infiltration, to take into account non-ideal mixing of tracer gas in a building. Considers versions of this model:< 1.
Common assumption is that tight houses cause mould. Questions this attitude and suggests that low-energy and very well insulated housing causes mould as a result of condensation.
Provides basis for planning and installing plant for maintaining indoor climate based on previous draft which is based on earlier Danish Standard.
The author examines the influence on thermal comfort of the air flow inside wall air spaces, on the assumption of a stabilized periodical condition.
Investigates the efficiency of models describing infiltration and natural ventilation in buildings. Considers 8 different models.
Studies the airtightness of about 50 passive solar homes located through out the USA using low cost measurement techniques.
