LoginHeat load from passage of cold outside air to building interior is function of wind speed and outdoor air temperature. Analyses meteorological data to determine suitable design conditions for accurate assessment of infiltration heat losses.
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.
Points out importance of ventilation heat losses in calculating total heat requirements of a building, and necessity of its analysis for multi-storey buildings.
Gives the results of measurements of wind and driving rain carried out over a 1-year period on an 18-storey block of flats, and compares these results with calculated and model scale data.
Defines ventilation requirements for spaces intended for human occupancy and specifies minimum and recommended air quantities for the preservation of the occupants health, safety and well-being.
Reports measurements made of wind pressures on a multi-storey building in London.
The significance of air tightness on building performance and the factors affecting the air leakage performance of the building enclosure are discussed.
Discusses toxic and flammable gases and vapours that lead to hazards in buildings. Examines trends in accidental deaths in the home in England and Wales from gas poisoning.
Presents some results not previously published of the full-scale loading project carried out at the post office tower, London.
Reports tests of air leakage made in the joints in a hospital building in gothenberg using a special pressure chamber. Describes test method and gives the values from five readings ina table.
Reports model scale experiments to investigate the validity of digital analogue methods of predicting natural ventilation. Finds calculated ventilation rates up to 30% higher than observed model ventilation rates.
Outlines the characteristics and physical properties of driving rain. Discusses natural wind and its strength, spectrum and velocity. Describes methods for the measurement of wind loads and of driving rain on buildings.
Reports environmental background radiation exposure measurements made in approximately 100 residences in the vicinity of Livermore, California showing variations in annual exposure from 52 to 130 mr.
Surveys published ventilation rates, primarily of single housing units. Finds helium is the most commonly used tracer gas and that average annual ventilation rate of most occupied houses is between O.5 and 1.5 air changes per. hour.
Data has been obtained on the radon concentration in natural gas supplied to several metropolitan areas in the United States.
An earlier paper gave the flow to be expected through an open door from theoretical considerations. Describes model tests designed to check these theoretical predictions.
Reports measurements of radon daughters in air. The daughters were collected on filters for different lengths of time. A silicon semiconductor detector and the etch foil technique were used to measure the alpha particles from the radon daughters.
One of a series of investigations of the improper functioning of ventilation and smoke stacks.
The adiabatic boundary layer appropriate to flow over an idealised urban terrain has been simulated using a modified version of the system previously used to produce a rural boundary layer simulation.
One important factor in the spread of airborne infection must be the movement of the air itself i.e. the ventilation, although an exact correlation of it with the risk of infection has yet to be found.
