LoginDescribes method for measuring the direction and volume of air flows in a building with several rooms. The method uses carbon dioxide as a tracer gas produced from dry ice in each room.
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.
This is a short guide to the choice of a type of window, considering its position and exposure to wind. Defines exposure grades for windows.
Reports investigation of air leakage through windows. Gives tables of air leakage of various types of windows with their dimensions, crack length, number of corners and length of air paths within cracks.
In a previous paper it was found that the number of persons occupying aroom, or the air space per occupant, is a very important factor affecting theper capita outdoor air supply for the control of body odors. In a room with a net air spac
Examines air flow into air-conditioned buildings caused by opened external doors in summer.
Gives an account of a method of measuring the ventilation rate of a room using hydrogen as a tracer gas. Describes katharometer used to detect the gas and the experimental procedure.
The work to be described here is an elaboration of Lehmberg's preliminary experiments.
Describes measurements taken in eight rooms in a multi-storey office building. Heat supply, internal to external temperature and pressure differences were recorded.
Describes measurements of heat flow taken in three rooms at different heights in a multi-storey office building. Heat supply, internal to external temperature pressure differences, wind velocity and sunshine were recorded.
Reports measurements made of the wind pressure over a model of the Empire State Building as affected by the presence of neighboring models simulating buildings which might be erected on the adjacent blocks.
Describes laboratory test performed on four steel swing windows and one steel double-hung window to determine leakage rates at different values of pressure and humidity.
States that it is usual to assume a certain pressure difference across a window for a given wind velocity. Describes method of recording and instrumentation used to record wind speed and direction and pressure difference across two windows.
Describes apparatus used to measure air leakage through walls, the types of walls and the test procedure. Gives results of tests on plain walls and shows the effect of adding plaster and paint.
Describes test apparatus and procedure and gives results of air leakage tests on various types of wood frame construction. Also gives the results of tests on the effect of adding sheathing paper, plaster, wall paper and paint.
Describes apparatus and method of testing wood windows. Each window was tested four times, twice closed but not locked, locked and locked with the sash perimeter sealed. Tests were repeated six months later and again after weatherstripping.
Reports tests made to determine the air leakage characteristics of various types of walls.
Describes apparatus and test procedure used to measure air leakage through metal windows and gives test results.
Presents results of air leakage tests made on a pivoted window in the Grand Central Palace building under both natural and artificial wind pressures
Presents method and results of laboratory tests on the air leakage of rolled section steel windows. Results show that steel windows manufactured of solid rolled sections are, on the average, more weathertight than wood windows.
Describes apparatus and test procedure of tests made to show the effect of caulking the crack between the brick wall and window frame and the effect of applying storm sash to the window on air leakage rates.
