LoginThe Delta-Q duct leakage test has been developed over the past several years as an improvement to existing duct pressurization tests.
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.
The humidity of rooms and the moisture conditions of materials in the enclosure of buildings depend much on each other because of the moisture exchange that takes place over the interior surfaces.
This paper contains a numerical study of the indoor temperature, humidity, and comfort and indoor air quality conditions in a bedroom located in Saint Hubert, Belgium.
The hygrothermal behavior of the building envelope affects the overall performance of a building.
In this paper the assessment of moderately cold environments with two different methods : the PMV method and the IREQ method. The applicability of the comfort criteria is analyzed too for a more general assessment of cold environments.
In this paper the methodological benefits and constraints of conventional climate chamber research in comparison to the field-based alternative are discussed.
This paper, on the basis of existing literature, sums up the factors that influence the human perception of air movement and it also tries to specify in general terms when air movement is desirable and when it is not.
In that study, two air supply devices were investigated in order to simulate the characteristic of natural wind.
Main environmental studies are today, outdoor air quality, but not indoor air quality though there is mounting evidence that exposure to IAQ is the cause of excessive morbidity and mortality.Research within the areas of developing countries has ha
The aim of this paper is to identify the link between indoor environmental factors and asthma or allergic symptoms among small children and their parents.
This paper presents the results of a field experiment made on 30 female office workers : they were investigated on their perception of environmental conditions and the intensity of the Sick Building Symptoms if any, at 3 levels of temperature and
This paper describes how the pollution loads in non-industrial buildings can be quantified by using the olf unit. It also sums up the existing data on the measured sensory pollution loads.
This paper summarizes a series of 10 experiments made in offices in order to quantify the effects of indoor environmental factors on performance.
This paper sums up the knowledge on good and bad effects of ventilation on health and other human responses. The focus is on working environment in offices and residential buildings.
That study was performed in a call center.
New methods were used for that study, to evaluate the factors affecting productivity. Parameters of fatigue were investigated along with task performance.
This paper analyses the quality level of CFD, different aspects of the boundary conditions of supply openings are considered allong with the prediction of wall jets by different turbulence models.
This paper first describes the analysis results of flow and temperature fields around the human body.Thanks to various examples, it is made clear that CFD has developed into a very effective and powerful tool for analysis and design of healthy ind
Individual differences in preferred air temperature may be as great as 10°C, and preferences for air movement may differ more than four times for the occupants.
Temperature and humidity changes can affect building materials and the building structure (deformation or breakage).
