LoginAirflow through openings in a cross ventilated building scale model was investigated in a windtunnel and by numerical predictions.
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.
Using computational fluid dynamics (CFD) techniques to model buoyancy-driven airflows hasalways proved challenging. This work investigates CFD modelling of buoyancy-driven natural ventilation flows in a single-storey space connected to an atrium.
In case of cross ventilation through the large opening, it is well known that the inflow directionat the opening is not normal to the opening.
The 40 story high-rise headquarter of the Deutsche Post AG in Bonn features an integratedcomfort and low energy concept. Contrary to common high-rise design, the building does not require a central mechanical ventilation system.
This paper investigates the single-sided natural ventilation through a VELUX centre pivot roof window under natural weather conditions.
The Effect of Wall Porosity on the Flow Rate in a Building Ventilated by Cross Wind | 2004 | English
Wind-driven cross-ventilation in a single-zone cubic building with two large openings is investigated using a computational fluid dynamics approach.
As ventilation is a significant consumer of energy the rates of ventilation have often been minimized, particularly after the energy crisis in the early 70s, in order to reduce equipment and energy costs.
There has been considerable interest in the interaction between buoyancy and wind pressure gradients on the overall structure of natural ventilation flows.
This paper describes a study on the performance evaluation of a hybrid ventilation systemwith a heat exchanger.
This paper discusses the concept and performance of a naturally ventilated building with a double-skin facade in Tokyo.
We report on a series of measurements of the temperature at Houghton Hall, Luton,over the Spring and Summer of 2003.
It is difficult to evaluate the effect of cross ventilation quantitatively, because the indoor environment under cross ventilation is uneven and changes with the outside conditions.
The natural ventilation of a room with a source of uniformly distributed heating at the base andwith vents at multiple heights is investigated both theoretically and experimentally.
The authors recently reported the detailed experimental results on that the discharge coefficient of the openings exposed to the wind driven airflow clearly changes depending upon the windangle and consequent conditions.
In this paper a method to solve a design problem of hybrid ventilation system is proposedby building stack pressure around the ventilator using a flat bed, glass-shielded rectangular solarchannel.
Natural night ventilation is an energy efficient way to improve thermal summer comfort.Coupled thermal and ventilation simulation tools predict the performances.
In this study, the houses located in the northern region of Japan had been investigated.
Tracer gas sorption in and permeation through building materials influence tracer gas ventilation measurements.
Carbon dioxide exhaled by people can be used as a tracer gas for air change measurements in homes. Good mixing of tracer gas with room air is a necessary condition to obtain accurate results.
In this paper a new test room for thermofluidynamic measurements is presented.
