LoginThis paper refers to the use of natural ventilation in Portuguese urban housing stock. In order to assess the goodness of natural ventilation design rules defined in a new Portuguese standard, a research project is being carried out.
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 IAQ characteristics and the corresponding health symptoms and thermal sensation of the occupants of child care centers in Singapore under 3 different ventilation strategies are reported.
This paper provides information of energy efficiency potential of Personalised Ventilation (PV) systems used in conjunction with a secondary Mixing Volume (MV) air-conditioning system in the tropics.
The microbiological quality of air was studied in a bread-making factory (100t/day).
The present paper evaluates indoor thermal environment, cooling efficiency and energy consumption between a floor-based system and a ceiling-based system using a mock-up model in cooling period.
This study presents the results obtained when Computational Fluid Dynamics is applied tocalculating the flow in a domestic kitchen hood at operating conditions.
This research proposes a method for task area wide-cover personal air conditioning thatprevents a human body in the task area from being exposed to a largely irregular thermal environment.
This study describes an experiment on a Task Unit and reports the results. The Task Unit coolsthe upper half of the body by isothermal air flow and warms the lower half of the body by a radiant panel.
The sick house syndrome has become a serious problem in Japan recently. It is important tospecify and quantify the source of chemical pollution.
Pressure loss mechanism at the inflow opening of Cross-Ventilation is studied by detailed analysis of LES results.
We performed numerical simulation of the inflow characteristics at an opening by using LES,the standard k- emodel, and the improved k- emodel that was applied Durbins limitation (hereafter, it is described as Durbins k- emodel in this paper).
The effect of draughts on the steady thermal stratification established by a localised heat sourceat floor level in a naturally ventilated enclosure with upper and lower openings is considered.
The proposed local dynamic similarity model can select an adequate discharge coefficient to match the approaching flow angle. This is an improvement over the conventional orifice flow model where the discharge coefficient is set to a fixed value.
The purpose of the present study was to evaluate the possibility to reproduce heat and air flowcharacteristics in a machine room where high heat generating systems and devices are installed.
A simple model of a rotating duct cleaning brush was presented using large deformation elastic theory. The results obtained by the model were compared with the results obtained by a laboratory test.
This paper presents the advantages and drawbacks of natural ventilation. .
In this paper the author relates his experiment : while interviewing unhappy building occupants he realized that it was necessary to step back from the specific complaints and begin with the basics of proper ventilation, moisture control, tem
An optimal placement of outside air intakes is important for a good IAQ protection. A proper intake placement can also reduce the need for filtration, and reduce re-entrainment of chemical emissions.
Electret media or "charged" media are electrostatically charged materials that attract, like magnets do, microscopic charged or uncharged particulates.
Ultraviolet germicidal irradiation (UVGI) systems are used to disinfect air, they consist in mounting shielded UVGI lamps at high level in an upper room zone, and the natural convection currents that occur in a room space carry airborne microorgan
