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.
This paper extends the integral mass balance approach to the remaining constant concentration technique.
This paper presents a new approach to determine the interzonal airflows of a multizone system using tracer gas measurements.
Sandberg and Skaret differentiate between the terms air change efficiency and ventilation effectiveness.
Combined ventilation and heating systems in floors demand extensive investigations about the heat transfer before they could be installed in residential buildings.
Simulation models basing on 2-dimensional finite-difference approach were developed for the steady-state and dynamic analyses of the thermal coupling of leakage airflows and building components.
The computer programs published so far have enabled the calculation of airflows at constant temperatures or of air temperatures at constant airflows.
The evaluation of a code can be done by investigating two items: solving the correct equations and solving equations correctly and eficiently. An indoor airflow code VentAirI has been developed and is evaluated here.
The concentrations of indoor pollutants should be maintained below recommended values at all occupied locations at any time.
A mathematical model has been developed which will facilitate the prediction of infiltration rates within multi-zone buildings.
The airflow pattern and thermal comfort in a naturally ventilated classroom were predicted using CFD techniques.
Results of 3-D computational fluid dynamic simulations of the air flows, temperature distribution and contaminant remove efficiencies for typical workstation configurations which include the option for localized supply of outdoor air will be prese
Numerical modelling is performed to predict air movement, thermal comfort level and contamination distribution within an open office space.
Modern inlet devices applied in the field of ventilation of rooms are getting more complex in terms of geometry in order to fulfil the demand for thermal comfort of the occupants in the room and in order to decrease the energy consumption This exp
Recent full scale experiments has detected the presence of low Reynolds number effects in the flow in a ventilated room.
The paper discusses methods to set boundary conditions at the air supply opening in predictions of room air flows with computational fluid dynamics.
Due to the limitations of computer storage and time the flow boundary conditions at an air inlet device have to be specified for numerical simulations of air flow patterns in rooms.
This paper is concerned with the application of air flow simulation in design.
Both infiltration and exfiltration has a predominant influence on the space heating requirements in cold climates. Good predictive design methods are required to estimate the air leakage component in buildings.
Influence of radiative participation of inside air on natural convection in a room. | 1991 | English
The basis of this study are experimental results obtained on a real scale cell in controlled climatic conditions which are used to show the potential influence of radiative participation of inside air on natural convection in a room.
