LoginA portable background gamma-radiation dosimeter with a high-pressure ionization chamber was designed. The gamma background radiation dose rate and radon concentration in the air of the 97 new flats were measured.
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.
Presents a new method for determining the airborne concentrations of RaA, RaB and RaC in atmospheres contaminated with radon-222.
Explains the principles involved in condensation and the conditions producing condensation, both atmospheric and other sources of moisture. The behaviour of absorbent materials and surfaces is described. Interstitial condensation is explained.
For use in various wind engineering applications, it is desirable to have a consistent relationship by which to project height variations of both 'instantaneous' winds and parameters of the wind speed probability distribution. The power
In this paper, some of the more fundamental notions of the phenomena classified as "subsonic aerodynamic noise" are prsented.
Describes a method of analysing the stack effect on a multi-storey building. The building is divided into zones and a computer programme calculates air-flow and pressure for each zone.
Describes measurements made of wind speed and direction and pressure differences across the exterior walls of two multi-storey buildings in Montreal.
Reviews wind research prior to 1958, which was based on the simple concept of a smooth air flow resulting in static design loads for most structures. States that research for the past ten years has benefited from three innovations.
Give method for collecting and analysing sulphur hexafluoride used as a tracer gas.
States that current methods of estimating heat demand of buildings are very inaccurate, and so large safety margins are used which usually result in overestimating the necessary heating plant capacity.
Describes main features of full-scale wind load tests made on Royex House, an 18-storey office block in London. Wind tunnel tests were made on a model of the building and the results compared.
Gives short state-of-the-art review of knowledge of wind turbulence. Mentions results from field investigations. Summarizes available knowledge. An appendix discusses hot-wire anemometry. Gives bibliography of subject.
Discusses the nature of stack effect, the distribution of air pressures across a building enclosure and its interior separations that stack action causes, and some of the implications of the resulting air flow patterns.
Discusses ways of modifying distribution of stack effect through building by design and construction.
Describes use of a radioactive tracer for measuring ventilation rates. Finds krypton 85 is the most suitable gas although xenon 133 and argon 41 have been used. Mentions various studies using radioactive tracers made in both France and England.
Reports study of the natural ventilation in elementary tall office buildings has been made using the analogy between the flow of air through a building and the passage of an electric current through a circuit of resistances.
