LoginA major cooperative study of the effect of ventilation of timber flat (cold) roofs on combatting condensation and moisture accumulation has been undertaken in Denmark.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
This paper describes a series of ventilation measurements carried out in two small factory units situated on an industrial estate in Newport, South Wales.
This study examines the experimental determination of the apparent net formaldehyde source strength in a group of sixteen nominally identical wood frame houses built by one contractor using similar construction details and materials.
A miniature passive perfluorocarbon tracer system was successfully applied to the determination of air infiltration and exfiltration rates from each zone of a multizoned structure, as well as the air exchange rates between zones inhomes, multiple
A simple means for determining air infiltration rates into homes and buildings for assessment of indoor air quality and energy conservation measures, based on a passive perfluorocarbon tracer (PFT) technique, was evaluated in a well-defined enviro
The interpretation of the data presented in the named article (by Nazaroff W W et al, NO 1767) is extended to develop an improved model that can be used to predict radon concentrations in the single family house tested and possibly inothers as wel
Measures of a number of ventilation parameters and of a number of pollutants from 21 locations furnished data for evaluating interrelations among commonly used descriptors of ventilation as well as their relation to frequently measured indoor gase
Several different ratings of building airtightness are used to report the results of fan pressurization tests. These are generally based on airflow rates at specific reference pressures, predicted by curve fits to the test data.
Fan pressurization techniques are being employed by an increasingly large number of contractors and auditors to determine the leakage characteristics of structures.
This paper deals with a new computer program, MOVECOMP, which calculates the in- and exfiltration and the airflows between the rooms of a multicell building.
Air exchange rates were measured in the National Archives Building under various combinations of temperature and wind speed.
Large, multicelled, and naturally ventilated buildings pose many inherent difficulties for the measurement of overall infiltration rates using tracer gases.
Tracer gas techniques for measuring airflows in buildings fall into three categories - dilution, constant injection, and constant concentration.
A new method for measuring interzonal air movement, using up to four different tracer gases simultaneously, has been developed at the Polytechnic of Central London and tested in a solar air-heated experimental house in Peterborough, UK.
There are three general categories of techniques for the control of radon and radon progeny concentrations in indoor air - restriction of radon entry, reduction of indoor radon concentrations by ventilation or air cleaning, and removal of airborne
The effects of retrofitting for building tightness, air-to-air heat exchangers, and HVAC circulation fans on radon and radon progeny levels were investigated using two matched test houses.
In the past several years measurements of radon and its daughters made in residential buildings in the USA indicate that in some situations the potential health hazard to the occupants of buildings from inhalation exposure can be significant.
Two techniques for estimating natural wind airflow through buildings for comfort cooling utilizing data derived from boundary layer wind tunnel studies are presented. One method is based on pressure and discharge coefficients.
Reliable surface pressure and indoor wind speed data from model buildings in boundary layer wind tunnels can only be expected if appropriate modeling parameters are considered carefully.
The steady-state heat loss of a house can be expressed as the sum of the above-grade conduction loss, the below-grade conduction loss, and the infiltration loss, minus the solar gain.
