LoginReports daily run-of-wind measurements, made for 3 years at distances of 3.5 h and 7 h to leeward of a 7-row shelterbelt about 6m.high.
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.
Measurements have been made of the air-leakage rates through structural components of conventional metal-panel and concrete buildings which may serve as containment for nuclear reactors.
An analysis of ventilation necessary to maintain air quality in an above-ground fallout shelter was done, making use of theoretical models, and generalizing the results to fit measurements on actual shelter data.
The paper is concerned with the procedure for regulating or balancing a ventilation· system, so as to ensure that each outlet supplies or extracts its proper quantity.
Proposes a method for measuring the rate of air change in factories using ammonia as a tracer gas and measuring its rate of decay by a colorimetric method. The advantage is that extremely small quantities can be detected.
Ventilation rates in two test home were measured using helium as a tracer gas. Pressure differences across the exterior walls of the house were recorded using pressure taps.
Reports investigation of air change rates in two residences using helium as a tracer gas. Gives results of measured air change rates, wind speed and direction and internal to external temperature difference.
Describes tests made on fifty different weatherstrips. Tests were made in the laboratory of airtightness, rigidity, ageing, load tests, freeze tests and wear tests. Strips mounted in windows were tested for ageing and resistance to driving rain.
Reports systematic pressure distribution measurements made on models of rectangular buildings of various heights with gabled roofs of different slopes in a wind tunnel. Describes the models and test procedure.
In connection with the revision of the German specification for loads due to wind, DIN 1055, section 4, an extensive review of literature was carried out.
This paper reports the results of measurements of inside surface temperatures on a basic double window arrangement consisting of two sheets of glass surrounded by insulated construction.
Model-scale tests in turbulent wind. part 1. Shelter at houses- dispersal of smoke. | 1963 | English
Describes instrumentation used to measure air flow and pressure. Presents laws for turbulent and laminar flow in a wind tunnel.
Reports measurements of infiltration rates in two research houses in Minnesota under different wind, temperature and inside operating conditions using helium as a tracer gas.
Gives equations and charts for the calculation of heat and moisture flow due to natural convection through openings in vertical partitions separating spaces at different air conditions.
Gives measurements of air infiltration made in ten houses in Indiana using helium as a tracer gas. Assumes linear dependence of infiltration rate on temperature difference and wind velocity and calculates infiltration rate per unit crack length.
Compares methods of calculating ventilation rates in mechanically ventilated animal houses.
Describes the basis of operation of electron absorption detector and the nature and causes of the erroneous and anomalous responses it may generate. Suggests pulse sampling technique asan alternative method of analysis.
Discusses the use of a tracer to measure the dispersal of air pollutants. Suggest use of Freon-12 or sulphur hexafluoride as tracer.
Discusses pressure distribution on buildings. Describes wind tunnel tests on model buildings. Pressure distribution on walls were measured in a constant velocity field and in anartificially produced velocity gradient.
