LoginDescribes the principal causes of condensation in dwellings in the UK. Monitoring the existing environmental conditions within a building, plus a structural and tenant survey, is required to determine the correct cure.
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.
Suggests draughtproofing and installation of controllable ventilation when retrofitting older residential buildings in the UK. Use of extract fans to remove moisture at source is recommended.
Measurements of the radioactive subsoil inside a closed and air conditioned room were made to establish how far the concentration of radon and the radon daughters may be changed by means of ventilation.
The Heat Protection Ordinance (Warmeschutzverordnung EnEG) issued in 1977 aimed to reduce heating energy consumption and has become part of the building ordinances.
Summarises risk by building type and the various physical processes involved in moisture transfer and condensation.
Discusses methods of preventing condensation: dehumidification, ventilation, controlling vapour flow; insulation and heating. Particular attention is paid to interstitial condensation and condensation in roofs
Describes the instrumentation and measurement technique used by the CSTB to measure the leakiness of residential buildings. Results of the experiments are also presented.
To make an evaluation of ventilation systems, numerical computation was carried out for three dimensional, isothermal, and turbulent flow schemes.
Discusses the sources of radiation exposure for the population of the UK. Radon is the most important natural element. Presents results of national and regional surveys.
Discusses problems of condensation in cavity roofs of industrial buildings, including ventilation air as a moisture source. Lists points to watch when foam filling the cavity.
Discusses use of a gas sensor developed on the Taguchi principle to measure air quality and control the volume of outside air introduced. Presents case studies of a concert hall and a lecture room, and calculates energy saving.
Describes experiments carried out by the Danish Maritime Institute using data from the Aylesbury experiments of the UK Building Research Establishment. The simulation of the standard rural terrain and the Aylesbury terrain was achieved by mea
The objective of this research is to obtain a correlation between air and sound leakages through slits.
Radon in indoor air is discussed in the perspective of the effective dose equivalents from other sources of radiation. Estimates of equivalents from indoor radon and its contribution to lung cancer incidence are reviewed.
The paper presents the results of the experiments accomplished in the Microclimatic Laboratory of the Hungarian Institute for Building Science on the problems of the discomfort feeling caused by draught phenomena.
Presents a chart for predicting the percentage of dissatisfied people due to draught in ventilated spaces, based on the results of a research project on perception of draught.
Discusses the current standards regarding indoor climate produced by ASHRAE, ISO and NKB. The parameters effecting thermal comfort and air quality are outlined.
Discusses the concept of ventilation efficiency.
The dairy plants of type MVA 1930 are compact structures with a floor area of 92mx120m. Despite this size the dairy plants - with the exception of certain special areas - can be naturally ventilated over long periods of time.
Presents the major findings from two studies of moisture problems in crawl spaces. Three mechanisms play a role: transport by air via the floor, moisture migration through the floor and cold bridges.
