LoginA method for following air movement within buildings, which uses several different tracer gases simultaneously, has been developed.
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.
During a 12 month period, an experimental house (retrofitted, with an air to air heat exchanger) and a control house are being monitored for various infiltration, indoor air quality and energy use parameters.
Uses air leakage measurements in laboratory and site studies in Poland to define a power law relationship between pressure acting across the opening and flow rate, and explains the effects on heat loss calculations.
Facts and ideas are presented to improve cost effective designs for airtightness and ventilation systems. Schematically alternative measures to save energy are presented.
A two-part experimental study was conducted to identify antecedents of complaints from office workers in a sealed, air conditioned building.
A capability to measure part-per-quadrillion concentrations of a family of perfluorocarbon tracers (PFTs) has been developed.
Presents the results to date of the use of the multiple tracer gas technique to determine interzonal airflow and ventilation rates in large, multicelled buildings like offices.
To measure actual air infiltration in dwellings due to the house and inhabitants it is necessary to measure continuously for several days. This can be done by the constant concentration measuring method.
The quantitative determination of formaldehyde in air using the fluorimetric acetylacetone method is described. Known concentrations of formaldehyde were generated and collected in water using absorbers.
The design and calibration of a passive sampler operating according to the diffusion principle and its application to the analysis of indoor air are described.
As airtight houses become more popular across Canada, reduced ventilation rates may lead to poor air quality and high humidity problems in these dwellings.
To elucidate any connection between high radon concentrations and low-infiltration houses, the 222Rn concentrations and infiltration rates have been measured concurrently in US houses.
The objectives of a ventilation system are to provide an aerial environment in which 1, animals' health and productivity can be maintained, 2, the stockman's comfort and health needs are satisfied, and 3, the building and equipment are protected f
To quantify the inferred elevated radon concentrations in energy efficient homes caused by lower air infiltration due to airtightness, an attempt was made to eliminate some of the more important conflicting parameters by measuring pairs of adjacen
An increasing incidence of 'building illness' is being noted among white-collar workers due to the high pollutant content of air in modern energy-efficient office buildings.
For controlling and for setting ventilation standards to maintain acceptable indoor air quality, it would appear to be of greatest importance to determine the strength of relationships between contaminant concentrations on one hand and different r
Automated system for measuring air-exchange rate and radon concentration in houses. | 1983 | English
The Aardvark automated system has been developed for continuously measuring the air-exchange rate and 222Rn (radon) concentration in an occupied residence.
The primary objective of this paper is to show the distribution of heat losses in prairie commercial greenhouses of various constructions and to suggest and test methods of energy saving.
Industrial buildings, particularly those containing nuclear and process plant, often require high standards of ventilation in order to cope with unusual features of the operations or process which take place within the buildings.
Naturally ventilated containers for international transport of hygroscopic commodities are now well established.
