LoginBriefly discusses wind-pressure on buildings. Derives equations for air-flow in a building without internal walls caused by wind pressure from perpendicular and oblique wind.
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.
The pressure drop and flow characteristics of short capillary tubes have been investigated experimentally for length-to-diameter ratios varying from 0.45 to 18 at diameter Reynolds numbers ranging from 8 to 1500. In the range of the dime
The wind pressures on a building can be decreased by a shelter hedge. Gives results of wind tunnel tests which show how this shelter effect depends on the distance between hedge and house, and on the wind direction.
Presents a new concept of describing the tolerance level of radon daughters. This concept is in terms of the alpha-energy dose resulting from the complete decay of the daughters.
Reviews qualities desirable in a tracer gas for the measurement of ventilation rates in buildings. Reports experiments in which radioactive argon was used to measure the ventilation rate in a room.
Reviews work done on the physical and biological effects of wind-breaks and shelter-belts, outlining main results. Discusses reduction in mean speed of wind, turbulence produced by shelter-belt, shading and humidity.
Describes a method for the investigation of ventilation rate in mechanically ventilated closed rooms.
Natural ventilation of inhabited rooms is studied with regard to its dependence on wind velocity and temperature difference between the interior of buildings and outside air.
The amount of air leakage through window gaps in buildings depends on the width and length of the gaps, the pressures across the buildings and the resistances in the air circuit.
Considers the characteristics of flow through small gaps. Discusses relation between wind tunnel measurements and actual wind pressure on buildings and the effect of building shape on ventilation.
This report describes research undertaken to investigate the various factors affecting the air infiltration through windows.
Describes tests made to find wind pressure on models in a low-velocity wind tunnel. Three basic forms:- a semi-cylinder, a rectangular vertical wall and a block-type gabled building were tested at several different angles to the wind.
Gives results of measurements of air-change rates and heat loss in occupied and unoccupied houses on two sites, one exposed and the other sheltered.
Briefly outlines the causes of natural ventilation which are wind and stack effect. Gives calculation of ventilation rates for a simple building. Discusses the effect of a more complex building plan.
Discusses conditions that must be satisfied for a model in a wind-tunnel to give the same air-flow as a full-sized building.
A systematic series of tests measuring probable distribution of wind pressure on buildings over a practically useful range of building proportions was undertaken using a three dimensional tunnel on a wide assortment of simply gabled block type str
The British Standard Code of Practice, and other authoritative guides, recommend minimum rates of ventilation related to the size and use of rooms, and structural means for providing them.
The fundamentals of natural ventilation are discussed with particular reference to the ventilation of houses.
Outlines ventilation measurements being made on two storey semi-detached houses using helium as a tracer gas.
Analyses theoretically the natural ventilation of buildings. Derives fundamental formula for the amount of ventilation due to temperature difference from Bernouilli's theorem considering buoyancy.
