LoginThe normally used equation for calculation of infiltration flow rates into a house is a power law of which the exponent n is normally assumed to be 0.66 but sometimes values of 0.5 or even 1 can be seen in the literature.
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.
Measurements in a test room of 28.4 m3 located at the top of a 3-storey building have been made to determine ventilation rates of different natural ventilation systems.
This paper discusses the potential for achieving an "energy-efficient" ventilation system by improving design procedures for natural ventilation. It considers ventilation requirements and the meaning of the term energy-efficient ventilation.
For optimum building design it is of importance to investigate the comfort and the energy conservation obtained with different types of ventilation systems and levels of airtightness of buildings.
The total energy consumption for five detached houses with air change rates of around 3 per hour right after construction, was measured and compared with estimated values, over a three-year period. Air change in the bedrooms was also measured.
Since 1974 the french Authorities have insisted on energy being saved in all buildings. There was very strong pressure on manufacturers to obtain better sealed window frames .
The aim of the present study is to measure the possible health effects among tenants after certain characteristic energy conservation measures had been taken in their dwellings. Changes in comfort are also included.
Describes a completely automated constant concentration tracer gas technique for measurement of air infiltration.
Reviews the most important sources of indoor air pollutants, and means of measuring the contamination of room air by persons (carbon dioxide and odours).
The emission of organic gases and vapours of solvent type from 42 commonly used building materials was measured under standard atmospheric conditions.
The state of practice in Canada, as described in the literature, concerning ventilation, air distribution and air quality in warehouses and light industrial buildings is reviewed. There is little documented field information available.
Addresses air leakage of warehouses and light industrial buildings including the significance of infiltration/exfiltration, air leakage sites, and measurement techniques.
Results from a two-box model for calculation of tracer gas concentrations in rooms are given and consequences of different definitions of ventilation efficiency are discussed. Results from three different series of experiments are presented.
Ambient temperature may influence both the emission and the perception of human odour. This paper studies how human odour is perceived at different temperatures.
Particulate and gaseous emissions from indoor combustion appliances.and smoking can elevate the indoor concentrations of various pollutants.
The indoor air of 60 residences in and around a Maryland suburb of Washington, DC, was monitored in a pilot study to determine residential radon concentrations.
Concentrations of airborne radon ranging from 0.05 to 135 pCi/L were found in houses in Maine. Track-etch cups were placed in five positions for 100 houses to determine integrated average radon concentrations over the period October 1980 - May
Modelling houses as two coupled chambers, namely, the living area and basement, predicts more accurately the total indoor radon source flux from building materials and geology than a one-chamber model in houses with disparate radon concentration
Discusses the nature of the problem of indoor air pollution, limitations in the authority of established health agencies in the US to control the problem, research needs and some control options.
A subcommittee of the Nordic Committee for Building Codes has released guidelines for building regulations regarding indoor air quality, especially concerning ventilation.
