LoginA three-dimensional drift-flux model for particle movements in turbulent airflows in buildings is presented.
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.
This paper describes the measured and calculated results of airflow rates and pollutant concentration profiles in an airtight test house, the aim being to evaluate the calculation model COMIS for multizone air infiltration and pollutant transport.
There are two main soil gases of current concern to human health. These are radon, which is a carcinogen, and landfill gas, which is explosive and toxic.
At present, Computational-Fluid-Dynamics (CFO) with the 'standard' k-e model is a popular method for numerical simulation of room airflow. The k-e model needs a lot of computing time and large a computer.
Convective heat transfer from internal room surfaces has major effect on the thermal comfort, air movement and heating and cooling loads for the room.
This paper presents a comparison of predictions from a duct efficiency model developed by the authors with measured real-time heating n, system efficiency measurements from six site-built residential homes with natural gas furnaces in the Puget So
The performance of a glazed solar chimney for heat recovery in naturally-ventilated buildings was investigated using the CFD technique.
Concrete may be cold and hard, but some energy- efficient builders have been warming to insulating concrete forms (ICFs). As ICFs become more common, home performance professionals need to know how they're built and how well they work
A house without a heating system in our cold climate - is it possible?
The BRE has examined the suitability, effectiveness and potential energy savings of retrofitting natural and low energy ventilation systems in UK offices during refurbishment projects.
