LoginExamines airflow in the Glowworm cave of New Zealand using conventional methods together with experimental procedures using SF6 and CCL2F2 tracer gases. Results show that the rate and direction of airflow are a direct response to a thermally
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 a project carried out by the Bonneville Power Administration where 18 houses at its Midway substation in central Washington were retrofitted and the results monitored for a 3 year period. The houses were divided into 3 groups. During
Measures houses with energy efficient designs in Eugene, Oregon and Rochester (NY) for effective leakage area using blower door fan pressurization. Determines air change rates by tracer gas decay analysis.
Describes measurements of the leakage area of fireplaces,bathroom and kitchen exhaust vents, electrical outlets and leakage in the ducts of forced air distribution systems.
Descibes tests conducted by the Pacific Gas and Electric (PGE) and the Bonneville Power Administration (BPA) to evaluate cost effectiveness of certain retrofits.
Notes that ventilation efficiency is not referred to directly in the new DIF standards for ventilation effciency.
Long-term efforts in Belgian research has led to the development of computer models for energy consumption predictions. Describes some simplified methodologies to be used for quick analysis of situations, especially in 2 cases:< 1.
Describes a test method for determining the overall heat loss coefficient of a house. Bases method on the statistical correlation of measured heat consumption with outdoor weather data.
Measurement of radon indoors - an evaluation of measurements. Radonmatning inomhus. | 1982 | English
Reports on radon measurements made in the municipalities of Uppsala, Sodertalje and Tyreso. Uses about 7600 kodak plastic films in private houses and bloks of flats.
States that a comprehensive sealing program should be considered in every residential energy conservation program.
Describes methods for measuring air flow rates and air velocities in buildings, with the aim of formulating identical rules within the Nordic countries for the inspection and adjustment of ventilation systems.
Uses wind tunnel model studies of houses to determine how best to reduce the surface pressure variations from wind and the associated air infiltration emphasizing the correct placement of suitably modelled coniferous trees.
Tests a room-size, residential air-to-air heat exchanger for effectiveness of heat recovery. Conducts experiments in a small wood frame building, the Test Chamber, on the roof of the lab building.
Examines and tests a number of commercial air-to-air heat exchangers to determine their performance as installed in each house.
Presents various measurement and inspection techniques for assessing the thermal performance of the exterior envelopes of buildings.
Subjects 11 private dwellings at Taby and 5 at Brunna (all 2-3 yrs old) to repeated airtightness tests over a period of two years. Finds the largest leakage is 2.5 ach and the mean leakage is 1.6 ach.
Describes a computer program developed for the analysis of residential building thermal loads and space heating and cooling energy use.
Describes a climatic chamber used to measure the concentration of formaldehyde and other volatile substances which may be emitted by furnishing and building materials.
Describes a study to map the ground wind conditions in the housing area Kroksback in Malmo, and to study the effect of various proposed measures to improve the wind environment.
Discusses the possible effects of wind, stack effect, vents and fans on air leakage, and the influence of air leakage openings and the location on the pattern of air flow through buildings.
