LoginConcerning pollution in Hong Kong, the situation is particularly serious in public transfer locations such as public taxi transfer interchanges.
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 deals with the effect of discharging the air from a diffuser elevated above the floor.
In so far as a CFD analysis is becoming more and more complex. The presentation of the results must be adapted according to the audience.
This paper deals with a computer simulation of airflow and indoor environment in livestock buildings. Simulation results have been analysed and visualized with a Virtual reality visualization .
Ventilation, air conditioning and air heating systems are of vital importance for the health and comfort of residents and other building users.
Describes two European research projects on performance criteria for healthy buildings in which TNO Building and Construction Research (The Netherlands) is involved : HOPE (Health optimisation protocol for energy efficient buildings : Prenormative
This booklet summarizes the work of IEA ECBCS Annex 35 'Hybrid ventilation in new and retrofitted office buildings' and is based on the research findings from the participating countries.
This report describes the characteristics of a thermodynamic concept, exergy, in association with building heating and cooling systems. It introduces the various forms of exergy and the mathematical formulations used to evaluate them.
The brochure describes the main characteristics and advantages of low temperature heating systems. It presents 8 buildings with such systems, briefly describing the building and its equipment.
Multiple-skin facades were studied by means of experiments and numerical simulations. Experimental work was done on naturally and mechanically ventilated single storey multiple skin facades.
From experimental data on eight common air diffusers, authors developed simplified methods (the box method and the momentum method) to describe air flow and temperatures in the air jet that can be used as imput data for room air flow CFD calculati
This article describes the various types of fungi (yeasts, molds, mushrooms, ...). It reminds that they are single or multi-cellular non-motile organisms which rely on other organism or environment for nutrients.
This article describes bacteria and viruses usually considered as candidates for biological weapons. It also presents chemical agents that might be used as chemical weapons.
The heterogeneous photocatalysis relies on the activation of a half-conductor.
The excitation of pulsed plasmas for the air treatment (odors, toxic and volatile gases suppression, and sterilization) needs fast high electric pulse generators with powers that can require high repetition frequencies according to the applicati
The new French regulation about energy performance of buildings (RT 2000) specifies airtighness criterion for ventilation network. The author gives a methodology to measure the overall airtighness of ventilation installations on site.
Results of on site measurements in office buildings relative to the performance characteristics of five ventilation networks are presented. The poor air tightness is responsible for defects and bad performance.
Air tighness of ventilation network is very important, so the manufacturers have developped sets of new sealed fittings. These new equipments have been tested in CETIAT laboratory.
The french standard NF S 90-351 has been modified to include a wider field of application. This standard now takes into account previsional aspects. It is needed to define "areas at risk", and materials and equipment performances.
Comments about the project of the new french standard NF S 90-351 "Clean rooms and related controlled environments in medical establishments" and the consequences on the design approach of clean rooms to master airborne contamination are given.
