LoginPresents results of an investigation aimed at working out thr design principles for natural ventilation conduits. Discusses results obtained in an aerodynamic wind tunnel.
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.
Compares the air change rates measured with SF6 and CO2 using the tracer gas decay technique and the fan extraction method over a wide variety of test chamber sizes and mixing systems.
Uses a similitude approach to develop predictive graphs for the ventilation rate due to the stack or chimney effect. Uses a half scale model of an open side wall structure with a continuous and restricted open ridge, and finds that:< 1.
Describes the results obtained and the problems encountered in the sealing and testing of 15 homes in Ottawa Ontario, for the Ontarion Ministry of Municipal Affairs and Housing.
Reports on a project carried out in the Caswell Hill and Riversdale areas of Saskatoon to investigate the effectiveness of sealing with caulking and weatherstripping to reduce air leakage.
Describes an analytical model used to study the effects of air supply rates on the dynamics of an occupied space as related to energy consumption and occupant's comfort.
Reviews literature and presents annotated bibliographies for indoor air quality, indoor air pollution health effects and residential air infiltration.
Illustrated booklet for the layman on heating and ventilation in housing which discusses the following: oil heating, wood firing, electrical heating, district heating, heat pumps, solar collectors for domestic hot water, ventilation systems, natur
Describes the conditions of the "Heat Recovery from Exhaust Air" group of projects of the Swedish Council for Building Research.
Comments on the benefits of tighter house construction and gives a summary of the current tightness levels of the US housing stocks, based on a 300-house survey of infiltration measurements.
Describes the Mobile Infiltration Test Unit (MITU) and its instrumentation, including some preliminary tests of the individual measurement systems.
Illustrates some practical aspects of the use of one IR camera and associated equipment discusses some of the problems in interpretation of some pictures representing temperatures of the inside and outside surfaces of buildings particularly proble
A model that relates fan pressurization results to infiltration values during the heating season is the basis for infiltration estimates in several different audit programs. Describes the model and presents validation results.
Tests a large office building, consisting of several octagonal towers and other blocks in a boundary layer wind tunnel. Determines the highest suction pressures which are relevant for the fixing of the cladding.
Describes a comprehensive investigation undertaken to determine the wind pressures on surfaces of models of typical low-rise buildings. For many practical applications building surfaces like facade coverings or tiled roofs are permeable.
Measures air permeability of 21 facades of occupied dwellings. Investigates what proportion of air permeability is due to various gaps (moveable sections) and joints (between fixed sections) in 12 of the facades.
An energy-efficient residence in Mt. Airy, Maryland, USA, was monitored for aldehydes and radon in order to develop relationships between air infiltration rates and contaminant levels.
This paper describes the procedures used in residences for rapid grab-sample and time-dependent measurements of the air-exchange rate and radon concentration: the radon source magnitude is calculated from the results of simultaneous measurements o
Twelve energy-efficient houses in Eugene, Oregon, USA, were measured for effective leakage area using blower door fan pressurization. Air exchange rates over a period of several hours were determined by tracer gas decay analysis.
Discusses the sources and concentrations of organic compounds in indoor environments. Describes work done by the Lawrence Berkeley Laboratory in the USA on formaldehyde and poor air quality in offices.
