LoginDescribes a series of experiments to determine the ventilation performance of 2 different models of wall or window mounted heat exchangers.
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.
Looks at ventilation requirements for both odour and physical acceptability and pays particular attention to the differences between smoking and non smoking occupancy in an environmental chamber.
Compares measured hourly data on indoor humidity with data obtained by calculative values for NBS Houston test houses and for the high mass test building in an environmental chamber.
Data collected in a LBL study on ventilation in four public buildings includes sensory evaluations of indoor environment and of physical and chemical properties of indoor air.
Over 200 reports of health hazard evaluations are available of sealed, air-conditioned buildings, requested by occupants who believe their buildings to be hazardous to their health.
Describes method which permits long term tracer gas measurements in several separate rooms simultaneously.
Discusses principle that the position of supply air devices has a considerable influence on the ventilation efficiency that can be achieved. Considers factors affecting ventilation efficiency and different ventilation models.
Indicates that 35-70% of a building's annual energy consumption is used by ventilation plant.
Indicates that a systematic analysis is necessary if satisfactory results are to be achieved and suggests various stages of analysis. Provides practical examples with illustrations.
Notes that many air conditioning and industrial installations function inefficiently since too little attention is paid to air movement in a room. Compares effect of inlet and exhaust air devices.
States that as many as 600 lung cancers a year may be attributable to radon gas, and this may jump to as many as 1500 if energy conservation measures reducing draughts become more widespread. Notes that radon appears to be present in every hou
Presents a review of the main methods used for the study of air movement.
Describes a national demonstration of the effectiveness of an optimal weatherization programme for low-income families conducted by the Community Services Administration and the National Bureau of Standards. 101 family dwellings in 12 cities
Proposes a new experimental technique for investigating the natural ventilation potential of new building designs. The method tests scale models of ventilated buildings outdoors in the natural wind.
Describes large-scale field studies to investigate the effectiveness of measures to prevent condensation in some 4-storey blocks of walk-up flats in Stirling. The remedial measures in the blocks of flats are improvement of thermal insulation
Discusses the Hjortekar project of 6 low energy houses, built as part of the Danish Energy Research and Development Programme. Explains some of the construction details to avoid cold bridges and ensure airtightness.
Measures air change rates in a 2-storey detached house with operation of various types of mechanical fresh air ventilation systems. Studies 4 systems, including 2 balanced systems and 2 exhaust-only systems.
Defines requirements for suitable indoor air quality and examines the technical and economical possibilities of suitable methods of ventilation.
Compares wind pressures measured on a 1:25 scale model of a mobile home with results from a full-scale investigation.
Describes several types of door closing or air containment devices for use in industrial buildings, including automatic doors, flexible doors and air curtains.
