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 that study, IAQ measurements were carried out in 3 residential Singapore dwellings. CO2 levels were higher in air-conditioned bedrooms than in naturally ventilated bedrooms.
There is a resurgence of interest in naturally ventilated offices. Most of the time, cooling the buildings is possible with the opening of windows.
In a test cell equipped with an operating table, a medical lamp and a manikin representing the surgeon, air velocity and tracer-gas concentration were automatically measured at more than 700 points.
For that study, the constant concentration dosing method and the decay method were used to test air changes performances in an office equiped with a VAV mechanical ventilation system and in a domestic apartment with natural ventilation .
The principle of displacement ventilation involves air supply and distribution in a room by upwards displacement, i.e. as direct as possible through-flow in the occupied zone in order to achieve high ventilation efficiency.
A number of emission classification systems changed the test method and/or the classification values, like DIBT, EMICODE, and GuT. New classifications were born, e.g. Natureplus. Harmonisation of the testing protocols showed some progress.
Exposure risk assessment of any possible release of chemicals from manufactured products, and their possible impact on health and environment is now an important requirement by the European Commission.
Dissatisfaction with the indoor environment in many buildings occurs even when existing ventilation standards and guidelines are met.
This paper presents a prediction model of the blade trailing-edge noise and its validation from tests carried out on a fixed flat plate at different angles of attack in an anechoic wind tunnel.
Recent work on the prediction of airflow generated noise in ducts based upon pressure loss characteristics is applied to a range of in duct components including bends and branch take-offs.
ASHRAE has recently published its first residential ventilation standard, Standard 62.2-2003.
This paper focuses on the relations between ventiliation systems, indoor air quality and energy consumption.
Suppliers of heating, venting and air-conditioning products have leant on metalforming technology to pump out products that perform at higher levels of energy efficiency.
In this paper three real-world air-handling system problems are examined : the issues are discussed, troubleshooting techniques, solutions and lessons learnt are presented.
The aim of this paper was to check whether an integrated air purifier is suitable for controlling air quality and for the prevention of virus transmission through the central air system.
The major concern for HVAC's professionals is the engineering of indoor environments, but health and safety must be a primary concern too.
Natural ventilation is a sustainable, energy-efficient and clean technology that is well accepted by occupants.
According to its location, thermal mass can be approximately classified into two types: external and internal.
An overview is given of the current position regarding the use of wind tunnel modelling and envelope flow theory for determining natural ventilation through large openings.
