LoginReports measurements of air infiltration and leakage using tracer gas and the pressurization technique in a three bedroom townhouse having a gas-fired forced-air furnace system.
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.
Ventilation measurements in new Swedish houses show that they seldom fulfill minimum requirements of 0.5 air changes per. hour applicable to specific housing classifications. Basic natural ventilation is often used.
Indoor air quality in an air conditioned California high school has been measured over a variety of ventilation rates ranging from 13.3 cubic feet of outside air per minute for each classroom occupant to approximately 1.5 cfm per occupant.< Par
The reduction of ventilation in buildings as an energy saving measure may result in a deterioration in indoor air quality. Suggests use of contaminant control devices and summarises devices available.
Discusses materials and systems for reducing or eliminating air infiltration through identified leakage sources. Methods include caulking, adhesive/glass mat, weatherstripping, vent dampers etc.
Compares some existing performance requirements for air permeability and water-tightness of windows. Gives tables showing main European standards.
Discusses the use of a regenerative air-to-air rotary heat exchanger (thermal wheel) for heat recovery in residential ventilation systems.
This sixteen-page digest provides a guide to why condensation occurs in buildings and how to avoid it. Outlines causes of condensation problems in buildings.Gives 9 case studies. Discusses physical principles of moisture transfer.
Reports findings of investigations carried out by West German Federal Ministry of Health in July 1978 into the internal climate in the one third of the rooms in a representative West Berlin school which are located in the building core.
Describes a model for calculating air flow in mechanically ventilated high-rise building. Gives simplifying assumptions of model and basic equations of flow for the network of air paths.
Reports wind tunnel measurements of the wind-induced internal pressures of models of low-rise buildings of different geometry and internal volume.
Describes the six low-energy prototype houses constructed by the Low-Energy Project of the Danish Ministry of Commerce. Occupation of the houses is being simulated for approximately 18 months.
Air pollution from combustion of fossil fuels can be injurious to health causing damages to air passages. Discusses health risks caused by radon emission in houses.
Lists sources of radon and its isotopes in housing. Diagrams illustrate radon content as a function of air change rate. Estimates risk factors. Notes lack of coordinated national or international regulations.
During the period 1973-76, measurements in housing where particle board is used as a building material have revealed a reduction in the formaldehyde content of the indoor atmosphere from 0.64 to 0.40 mg/cu.m.
An energy saving survey was carried out in an office building in Stockholm during the autumn of 1978. The measures which were proposed are now being carried out.
The heat transfer characteristics of a window system are generally specified by three static measurements; winter U-value, shading coefficient and air infiltration. Outlines methods for measuring these three values.
