LoginMeasurements of the dynamic heat transfer in a four-bedroom townhouse were made under controlled conditions in a large environmental chamber to explore the viability of a computer program developed at N.B.S.
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.
Describes research to study movement of air through fully or partially open doorways with and without influence of temperature, and to ascertain amount of supply air required toprevent this movement. Studies door openings of 0.10 to 104 m.
Summarises research into air leakage. Describes field studies of air leakage of exterior walls, the heat loss caused by stack effect and smoke movement caused by wind and stack effect.
Describes experimental techniques used in the low-speed wind tunnels at the Building Research Station when studying air flow around buildings and pressure distribution over their surfaces.
Describes how internal heat sources such as bathrooms and kitchens can significantly influence stack effect in high rise residential buildings.
Reports project to measure wind pressures on low-rise buildings. Describes site and houses in the estate selected for investigation. Gives details of an associated experimental building.
Describes the research being undertaken by the British Gas Corporation on adventitious ventilation.
Describes computer program used to calculate air flows and pressure differential in a building as a result of a combination of wind effect, stack action and the operation of air handling systems.
Outlines projects at the Division of Building Research to carry out extensive field observations and studies of loads particularly snow loads on roofs and wind pressures and suctions on walls of high-rise buildings.
Reports wind tunnel investigation of the wind pressure on houses. Tests were made on model of traditional form with sides in the ratio 1:3 and 1:6, roof pitch of 14 and heights of 2,3,4 and 8 storeys.
Discusses some problems of providing weathertight joints between window and wall. Mentions sealing failures, condensation, frame defects and poor dpc detailing as important reasons for water penetration around windows.
Reports natural exposure test on vertical joints in open-jointed rain screen cladding. Describes test rig and gives results of water penetration tests. Gives design recommendations for screens.
Reports tests using a natural exposure rig on a number of designs of horizontal and vertical joints employing labyrinths to separate the air and water entering the joint.
Sets out in general terms the design principles for avoiding condensation in roofs, pitched and flat.
Reports 100 measurements of formaldehyde content of the indoor atmospheres of 25 rooms in 23 dwellings, mainly in new or recent one-family houses with varying quantities of particle board.
Discusses in detail a general ventilation model, which relates indoor pollutant concentrations to those outside.
Reports wind-tunnel measurements of wind pressure on a rectangular block. Presents results as mean isobars plotted on an exploded view of the surfaces of the model. Briefly discusses the effect of turbulence and fluctuating pressures.
Uses Turk's equation to obtain CO concentration v time curves in an office and a one-family house. Compares results with similar studies, current threshold limit values and ambient air quality standards for CO.
