LoginThis study aims at checking the viability of natural ventilation in urban environment, especially in street canyons. Reduced wind velocity, urban heat island, noise, pollution are barriers for a natural ventilation in town.
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.
For the evaluation of IAQ in ventilated rooms, local mean age of air is an important index.To model the spatial-temporal mass distribution in an imperfectly mixed forced ventilated installation, a data-based mechanistic approach was used.
The examination of the effects of cross-ventilation when a porous hedge is placed ahead of a residential building is presented in this paper.
This study reveals the effects that porous residential buildings have on the natural ventilation performance and on the cooling load reduction too.
Application of COMIS software for ventilation study in a typical building in Serbia | 2006 | English
The investigation of natural ventilation with the software package COMIS (Conjunction of Multizone Infiltration Specialists) in a typical building in Serbia was the aim of that study.
At a point-source release, point-wise concentrations may greatly exceed the well-mixed conditions.
The authors take the historic centre in Portugal as a case study.
Here is presented a detailed evaluation of different modelling approaches for the prediction of CO2 levels in occupied spaces for small, single-zone commercial buildings that use packaged air-conditioning equipment.
The authors carried out a study on ventilation systems working in the cul-de-sac of a coal mine. In a real mine gallery, measurements were made with a hot-wire anemometry and then used for the validation of a numerical model.
For the investigation of airflow and pollutant distribution in the isolation room of a hospital, objective measurements and CFD modelling based on three ventilation strategies have been carried out.
Field measurements and thermal comfort survey were carried out to evaluate the thermal comfort perceptions of a Hong Kong hawker center.
In that paper, a computer simulation of the air-circuits of a variable-air-volume (VAV) air-conditioning system is developed, then validated.
The impact of temperature differences within a room on spatial contaminant distribution is studied in that paper. A photoionization detector was used to monitor the tracer gas concentrations at 144 sampling points.
This paper describes an approach that has been undertaken to improve the airtightness of a number of plasterboard-lined load-bearing masonry dwellings that were constructed in the early 1970s.
Virus transmission through the vertical drainage stack is believed to have been one of the causes of SARS transmission in Amoy gardens, a high-rise residential housing estate in Hong Kong.The authors present their findings on the building draina
Experimental and theoretical investigations along with CFD modelling considerations are discussed in this paper to evaluate the performance of a square section wind catcher/tower turret system for natural ventilation.The modelling results tally w
A review of previous studies and reports on laboratory and field studies developed in the aim of assessing the performance of ventilation systems in spaces where smoking is allowed, is presented in this paper.The problems associated with those stu
For that study, the software package TRNSYS (transient systems simulation program) has been applied to estimate the energy consumption of a typical operating theatre in a tropical climate (Malaysia).
This paper provides an overview of mixed-mode buildings, and some of the research that is investigating their performance is described.
OA supply rates are often poorly controlled, but accurate measurements of OA flow rates are necessary. This paper describes results of tests of three technologies that perform well and advises on how those technologies should be applied.
