LoginDescribes the thermal and ventilative properties of some older dwellings and the latest test dwelling in Hokkaido. Results include the following.< 1) The above mentioned older dwellings suffer a great heat loss by ventilation and conduction.
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.
Presents a long term calculation method for indoor air temperature and moisture variation related to the water vapour condensation problem in a detached residence. In this method, the multi-room infiltration calculation is developed.
Reports results of a project to assess energy conservation measures in a group of typical three-storey, naturally ventilated, blocks of flats, built in 1940 in Stockholm.
Presents the results of a series of wind tunnel tests in which the surface pressure fields of low-rise buildings have been studied.
Radon, an inert radioactive gas, and its products of decomposition, will attack the lungs when present in high enough concentrations. Notes high concentrations of radon in mines and other underground spaces and even in well water.
Discusses acceptable levels of CO2 contamination in occupied rooms. Describes measurements in a classroom over 3 days using an infra-red analyser with natural ventilation via the windows.
Discusses condensation within dwellings. Treats conditions conducive to reducing risk of condensation, factors which control concentration of water vapour in the air in a building and temperature of building fabric.
Reports experimental measurements carried out in a boundary layer wind tunnel at the University of Western Ontario. Both external and internal pressures on two different models were measured with different porosities for the walls.
Reports insights from research project "Optimalisatie koelhuisbouw" (Optimisation of cold store buildings) by the Delft Technical University for the Foundation for Cooling Technique Development.
The Alberta Home Heating Research Facility consists of six uninhabited wood frame single storey modules with full basements. Describes the modules which are designed to test domestic heating strategies in a northern climate.
Treats drawbacks of current methods used in East Germany of calculating vapour barriers used to protect building elements from condensation.
Steeply sloping ventilated roofs are preferred for single and two-family houses in West Germany. Notes lack of any scientifically substantiated notions concerning physical laws governing air exchange between ventilated zones and outside air.
Reviews ventilation criteria for occupied buildings. Considers minimum ventilation for the control of carbon dioxide, odours, cigarette smoke, moisture and radon. Discusses future work to improve ventilation routes.
The requirement for better methods of predicting infiltration and natural ventilation rates has been reinforced by the incentive to reduce energy consumption in buildings.
Outlines factors influencing natural ventilation rates. Discusses techniques for measuring natural ventilation.
Briefly reviews factors to be taken into account in considering natural ventilation in commercial and industrial buildings.
Assesses the role of natural ventilation in modern hospitals.
Gives results of a statistical survey of energy consumption in British government buildings. Suggests one reason for high consumption may be excessive ventilation.
A market review of inlet/exhaust ventilation with heat recovery in single family houses. Traces recent developments in new house production.
Reports measurements of air leakage rates in the four energy-conservation research houses using the fan pressurization method. One of the houses is standard for the area and the other three houses have added insulation and vapour barriers.
