LoginDescribes a simple method of controlled ventilation comprising an extract system and air inlets.
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 a programme of ventilation measurements performed on a group of energy efficient houses built in the mid-1970's and situated in Abertridwr, S.Wales. Pressurization, tracer decay and British Gas autovent techniques were employed.
Outlines project where 25 representative dwellings from Birmingham Local Authority Housing stocks were monitored before and after energy retrofitting.
Discusses air quality and the related definitions of ventilation efficiency. Suggests a definition of efficiency for ventilation systems in residential buildings that takes into consideration how ventilation air spreads within a dwelling.
In future, high altitude correction factors will be considered in computing the ventilation heat load in high rise buildings. The algorithms necessary for the calculation are deducted and stated by the author.
Presents the operating principles for four basic types of air-to-air heat exchangers suited for small scale use: rotary, coil-loop, heat pipe and plate. Discusses individual advantages and disadvantages.
Uses the SEGAS "Autovent" constant concentration apparatus to measure the fresh air entering and the local ventilation rate in each cell of amulti-celled dwelling with both natural and mechanical extract ventilation.
Gives results from fiel trials of the performance of various mechanical ventilation systems. Carries out measurements in buildings built during the seventies, using the tracer gas decay technique with N2O. Tests 3 cases:< 1.
Describes experiments carried out in 4 low energy electrically heated houses incorporating extra thermal insulation and heat recovery mechanical ventilation systems.
Explores the various roles that mathematical models can play in the design of energy efficient ventilation systems.
Illustrates the building, comprising 24 flats in four storeys constructed in 1957 and heated by an oil fired boiler. Notes the intensive monitoring of the thermal characteristics of the building since 1980, with readings from 600 sensors.
Provides the first results of a comparison of computer predictions of building energy demands with measurements in actual buildings - the Maugwil single family house and the "La Chaumiere" block of flats.
Reports measurements carried out from summer 1979 to summer 1981 in a well-instrumented unoccupied house, and in a less intensive manner in 60 occupied houses of the same construction.
Provides results of research in Switzerland into window ventilation in typical rented dwellings as a function of outdoor climate, and the research support activities of the Air Infiltration Centre in the UK funded by the International Energy Agenc
Lists in a table and discusses the chief sources of indoor air pollution. Distinguishes between short term and long term pollution. Provides advice for reducing pollution from various sources.
Describes a mathematical model for the detailed calculation of ventilation losses in buildings.
Lists and explains the 10 rules to ensure correct domestic ventilation< 1. Ensuring the correct air supply< 2. Maintaining correct flow directions< 3. Maintaining stable ventilation conditions< 4. Avoiding discomfort zones< 5.
Discusses some problems of interpretation of the French regulations concerning domestic ventilation promulgated 24th March 1982. Notes in particular problems connected with natural ventilation.
Treats the research programme initiated by the Ministry of Research and Technology with the aim of achieving a more rational use of energy in dwellings by air conditioning and ventilation measures.
