LoginDescribes apparatus and experimental techniques for full and model scale measurements on test buildings. Discusses "blocking effect" of a large model in a small tunnel.
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 number of cases of water and frost damage in masonry and non loadbearing walls have been examined. This damage could not have resulted from vapour diffusion or rain penetration and is primarily caused by condensation due to exfiltration of air.
Points worthy of consideration regarding air leakage, i.e. the causes, identification, problems and remedies are briefly discussed generally without technical details and some illustrations are given of problems.
Reviews sources of window air leakage information in the current ASHRAE guide and data book, and standards for air leakage values recommended by industry. Gives results of air leakage tests made on thirty-nine residential windows.
Examines the conditions that develop inside an enclosure subjected to wind pressures, by analogy with a rectangular box held motionless in a stream of water.
Describes standard tests for air leakage, water-tightness and mechanical tests to be carried out on windows. Describes apparatus and test method.
Reports results of measurements of the environmental radiation inside Norwegian houses.
Reports study of 800 paired samples of indoor and outdoor smoke and SO2 concentrations of 60 Rotterdam homes.
Gives theoretical calculation of the amount of air which moves from one room to another due to a temperature difference between the two rooms.
Reports daily run-of-wind measurements, made for 3 years at distances of 3.5 h and 7 h to leeward of a 7-row shelterbelt about 6m.high.
Measurements have been made of the air-leakage rates through structural components of conventional metal-panel and concrete buildings which may serve as containment for nuclear reactors.
An analysis of ventilation necessary to maintain air quality in an above-ground fallout shelter was done, making use of theoretical models, and generalizing the results to fit measurements on actual shelter data.
The paper is concerned with the procedure for regulating or balancing a ventilation· system, so as to ensure that each outlet supplies or extracts its proper quantity.
Proposes a method for measuring the rate of air change in factories using ammonia as a tracer gas and measuring its rate of decay by a colorimetric method. The advantage is that extremely small quantities can be detected.
Ventilation rates in two test home were measured using helium as a tracer gas. Pressure differences across the exterior walls of the house were recorded using pressure taps.
Reports investigation of air change rates in two residences using helium as a tracer gas. Gives results of measured air change rates, wind speed and direction and internal to external temperature difference.
Describes tests made on fifty different weatherstrips. Tests were made in the laboratory of airtightness, rigidity, ageing, load tests, freeze tests and wear tests. Strips mounted in windows were tested for ageing and resistance to driving rain.
Reports systematic pressure distribution measurements made on models of rectangular buildings of various heights with gabled roofs of different slopes in a wind tunnel. Describes the models and test procedure.
In connection with the revision of the German specification for loads due to wind, DIN 1055, section 4, an extensive review of literature was carried out.
