LoginPresents diagrams showing the behaviour of air currents in two passive solar houses. Suggests some straightforward means by which repetitive patterns of discrete currents can be engineered.
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.
Discusses five different models for predicting air infiltration. Presents a new model developed at the Institute of Gas Technology.
Reports field monitoring program by the Lawrence Berkeley Laboratory to assess the potential impact of reduced ventilation of indoor air quality. Three houses, designed to be energy-efficient, were monitored using a mobile laboratory.
Describes the use of mechanical ventilation coupled with heat recovery devices in residential buildings to maintain acceptable indoor air quality and conserve energy. Gives tables showing the energy saving possible with a heat exchanger.
Reports a series of tests of the air leakage of new homes built and sold in the Ottawa area in 1978. The homes were tested by depressurizing them to apressure difference of 10 Pascals. 80 tests were made involving 63 houses and 9 builders.
The potential for air conditioning energy savings using exhaust fans to cool attics was investigated in six occupied townhouses at Twin Rivers. These houses were compared with similar houses without attic fans.
Gives comprehensive and detailed instructions for the design and construction of airtight buildings. Discusses the problems involved in building an airtight house.
Reports 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.
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.
