LoginDiscusses the problems of modelling natural wind in a wind tunnel and notes lack of comparison between full-scale and wind tunnel studies. Reviews past work which often shows marked discrepancies in wind tunnel data.
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.
A comprehensive manual describing theory and techniques of thermography as used to determine insulation defects in buildings. Describes operation of infrared camera and theory of interpretation of thermograms.
Describes a photo-electric technique for instant determination of contaminant concentration in wind tunnel studies of stack gas dispersion.
Reports experiments using sulphur hexafluoride as a tracer gas to obtain quantitative data on actual residence time distributions in rooms and hallways and contamination caused by reentry of laboratory fume hood exhausts into a building.
Investigates use of an array of spires, located at the entrance to the working section of a conventional wind tunnel, as a means of generating thick shear layers with properties similar to those of the neutrally-stable atmospheric wind.
By-product gypsum, produced as a waste in the phosphate industry, could be used in bulk as a building material but it has a higher radium content than other building material.
Discusses flow of air between two rooms through an open door. Considers 6 cases with and without mechanical ventilation and with a temperature difference between the two rooms. Gives examples of the calculation of air flow.
Measures the pressure on the outlet of a flue on a free-standing scale model in the wind tunnel at IG-TNO, as a function of the height of the flue outlet above the roof, of its position on the sloping roof and the pitch of the roof.
Describes a research project undertaken at the Building Research Station to measure wind pressures on the G.P.O. tower, London, and dynamic strains in the tower shaft.
Outlines the principles of infrared thermography and describes the equipment. Reports investigation at the National Swedish Institute for Material Testing into the use of thermography.
This draft gives provisional recommendations for performance requirements for windows. Gives grades of exposure, speed correction factors for ground roughness and height above ground level.
Infiltration and its effects, measurements, calculations, and typical values are presented and discussed.
Describes a diagram from which heat losses due to infiltration according to German standard DIN 4701 can be obtained, as well as rate of air infiltration per unit length of crack.
Presents calculations of mean temperatures and relative humidities , shown graphically for three typical housing types assuming different heat and moisture inputs: 1) whole house uniformly heated with moisture from household activities uniformly d
Full scale measurements were made of wind pressures on the 177m high post office tower, London. The variation of pressure with height was studied from recordings made at nine different levels between 49m and 168m above ground level.
Describes method for simulating natural wind boundary layer in a conventional, short working section, aeronautical wind tunnel.
