LoginDescribes a demonstration project to show that, in well sealed houses, trickle ventilators can provide an opening large enough to reduce condensation and odour problems, but small enough to avoid any significant increase in energy use.
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.
Describes experiments to measure the ventilation rates of two small open-plan factories, one typical of current design and one designed to be more energy efficient, with increased levels of insulation and a tighter method of construction.
Describes laboratory tests to find correct operative conditions for a controlled outside air intake through the air space in the window to provide efficient ventilation without creating draughts.
Describes how multizone tracer gas analysis techniques can provide a complete description of office ventilation. Treats the concept of ventilation effectiveness to characterise internal air distribution.
Describe tests carried out in an 850-seat auditorium of 4000 m3 to compare the readings of a CO2 indicator for controlling the ventilation air flow with the readings from a Stafa odour indicator.
Summarises measured data on energy savings from conservation retrofits in existing residential buildings, covering approximately 115 retrofit projects in four general catagories: utility-sponsored conservation programmes;low-income weatheriza
Points out that increased thermal insulation and draughtproofing of homes can increase the risk to health of indoor air pollution. Includes condensation as a pollutant along with associated mould growth.
This report details the development and field testing of a passive sampler system to collect gaseous and particulate contaminants in indoor air and the evaluation of the collected materials for biological effects using a simple bioassay system.
Briefly discusses the major concerns regarding indoor climate raised by the 'Indoor Air 1984' Conference in Stockholm and other such conferences: the need for an international information system on the influence of building materials andventilatio
Compares the guidelines for indoor air quality and minimum ventilation rates outlined in the DIN 1946 and ASHRAE standards. Discusses air quality-controlled ventilation.
The recommended limits for formaldehyde in indoor air are 0.1 ppm (0.12mgm-3). There are several ways of measuring the formaldehyde concentration, including sampling tubes.
Describes various methods for measuring formaldehyde in indoor air.
Due to the fact that loss of heat due to transmission is on the decrease, the loss of heat due to ventilation is becoming more important. Heat recovery units must be put into use to decrease the heat loss due to ventilation.
A mathematical model was used to describe the natural ventilation of a modern residential building for various building construction and meteorological data.
Describes measurements undertaken at the Fraunhofer-Institute fur Bauphysik of the effects of various mean and turbulent air flows under constant air temperature, indoor surface temperature, and humidity, using an anemometer and Laser Differential
Air exchange and ventilation efficiency. Luftutbytes- och Ventilationseffektivetet. | 1985 | Swedish
Several papers discussing ventilation efficiency, effective industrial ventilation, the positioning of ventilation inlets and outlets, displacement ventilation and other applications of the concept of ventilation efficiency.
Follows an article by M.Cadierigues in Promoclim E, December 1984, describing radon in the inhabited environment.
This paper describes the numerical analysis of room air distribution by the finite element method which can easily deal with any domain, the boundary conditions and so on.
Since 1973 there has been greater emphasis in Sweden on energy production and energy saving, but the products have often been of dubious design or benefit, and too expensive to be applied to normal residential Scandinavian housing.
Experimental methods have been developed to determine rates of air renewal. Based essentially on the use of a tracer gas, these methods permit the determination of real values on the site of the building itself.
