LoginDescribes monitoring of an office building where sick building syndrome symptoms had been reported. Data were taken under two different ventilation rates.
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.
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.
Notes the large savings possible if ventilation were adapted to the prevailing need. A promising possibility for indicating occupancy and thus the ventilation requirement is measuring the level of carbon dioxide.
Describes a field study carried out to evaluate the effectiveness of the air leakage sealing techniques employed by Ener-Corp Management Ltd. for reducing air infiltration in houses.
Tests a method which determines the infiltration of air and radon from the soil to a building. Makes measurements of total air flow along with usual airtightness tests.
States that comparison of different methods of calculating the volumes of outdoor air entering a building through the window shows that the chief deficiency of the standardised method of calculation is neglect of the importance of the relation bet
Tests and evaluates the air infiltration control methods employed in buildings. Concentrates especially on silicone sealant applied in situ to opening joints of external windows.
Compares and contrasts different methods of ventilation measurement in large buildings. Conventional methods of using tracer gas to measure ventilation rates in large volumes are cumbersome and expensive.
A short treatment of the concepts and aspects that play a role in ventilation is followed by a brief description of the investigation methods employed. Gives a concise survey of the equipment and mathematical models used.
Performs tracer gas measurements and fan pressurization experiments on an 8-storied student residential building in order to determine the influence of wind as well as of stack effect upon air infiltration.
Describes the retrofitting of a 14-storey office block in Oslo, done as part of an energy conservation project carried out in Norway 1979-82.
Describes the testing of 8 federal office buildings (size from 3000 sq.m.
