LoginDescribes a series of tests carried out in two interconnected environmental chambers, to determine the accuracy of airflows calculated from tracer gas measurements using a new rapid sampling system.
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.
Indoor air quality research in Canada is outlined. 17 indicators are being considered in drawing up air quality criteria and guidelines for residential application.
The theoretical background, admittance measurements and experimental work on interstitial condensation in lightweight roofs caused by air leakages is discussed.
Sets out the mathematical techniques for determining 1 the most likely position of the condensation plane, 2 the limiting humidity at a given room temperature, below which condensation will not accumulate within the structure, 3 the rate at which
Describes in detail a computer-based technique for predicting the risk of condensation occurring in building structures.
The Brookhaven air infiltration measurement system (BNL/AIMS) uses a family of four passive perfluorocarbon tracer sources and miniature passive adsorbent samplers to inexpensively but very effectively tag individual zones within multizone buildin
The manufacturing procedures and performance of a building air infiltration kit consisting of miniature passive perfluorocarbon tracer permeation sources and passive adsorption tube samplers are described.
Discusses levels of radon commonly found, the limits fixed by Sweden for buildings, and the health effects of these levels.
An air sampling and analytical system for formaldehyde measurements based on a solid sampler is described. The samplers were tested on a standard atmosphere in the range of 0.2 to 0.8 mg/m3 dry air.
This document reports on analytical work carried out in cooperation among three European laboratories.
Discusses the established principles and rules of air hygiene for animal housing and areas in which guidelines have yet to be devised. The most common pollutants are ammonia, hydrogen sulphide, methane and carbon dioxide.
The bacterial content of the air and physical environment of two crated veal calf units were monitored over the growing period of 16 weeks. The rate of release of bacteria colony forming particles (BCFP) from the calves was rapid.
Efforts to reduce the energy needs to heat or cool dwellings have the potential to create new health hazards.
A control program for a natural ventilation system for agricultural buildings is described which calculates a required ventilation rate, then adjusts vent openings to achieve this ventilation rate with equally distributed flows.
Presents general guidelines for selection and installation of air-to-air heat exchangers in cold-climate applications.
Compares the levels of possible cigarette smoke-related aerosols with the prevalence of health-related complaints in offices with different regulations about smoking, using data from two sources.
A review of 116 investigated incidents of building illness among office workers in North America and 27 buildings selected for investigations for reasons other than building illness has recently been completed.
1100 branch members of the New York branch of the Office and Professional Employees International Union working in nine office buildings filled out a detailed questionnaire on working conditions and health comfort complaints.
Tests were conducted in Ottawa during the winter of 1982/83 to investigate the effects of a gas cooking stove in the kitchen of an energy-efficient two-storey test house.
Air leakage is the single most important quantity in the determination of air infiltration in residential structures.
