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.
Proposes a two-layer turbulence model for predicting forced, natural and mixed convection in order to accurately and efficiently simulate indoor airflows.
Describes the use of a two-layer model to predict mixed convection. It uses a one-equation model for near-wall region and the standard k-e model for the outer-wall region.
Gives an overview of a computational approach to the so-called street canyon phenomenon, whereby microclimate influence on thermal loads of buildings and local contribution to temperature rise from air conditioning unit heat emission can affect th
Discusses the accurate evaluation of the effect of thermal bridges on building energy performance using a modelling approach. Sisley software was used first of all to model the heat transfers in the intersections of walls.
States that car park ventilation systems not only have to control the exhaust gases emitted by vehicles but take into account possible fuel spillages and the venting of smoke in the event of a fire. Explores ways of checking for compliance.
Describes how methods used in widespread energy efficient residential buildings in Germany are now being applied to larger buildings.
This article concentrates on displacement ventilation design procedures appropriate for rooms with heat- and contaminant-removal requirements.
States that when used with ice storage systems, cold air distribution systems are popular since they require less operating and capital costs. Stresses the importance of a consideration of occupant comfort.
Simulates a kitchen for a study of indoor air quality. An extractive FTIR technique was used to measure combustion products from unflued combustion from a gas cooker in a ventilated room.
Describes how a nodal model was developed intended to represent room heat transfer in displacement ventilation and chilled ceiling systems.
In order to explain the effect of ventilation systems, the article presents the results of investigations made on a simulation program to calculate the temperature, heat loads, ventilation rates and indoor air quality.
The Field and Laboratory Emision Cell (FLEC) was presented for the first time at the Healthy Buildings Conference in 1991. The FLEC is now used worldwide for many different applications that are related to emission testing of building products.
The project is a survey of 12 'off-grid' households across Canada.
The research project had the following objectives: document the development of a building envelope retrofit strategy for a high rise apartment building; monitor, assess and document the performance of a high-rise apartment building envelope retrof
Examines the difficulties of ensuring occupant comfort in challenging climates and less developed areas of the world such as the Galapagos. Temperatures can reach 30 deg C, but rarely go lower than 18 deg C, so no heating is needed.
This document, which is part of a public survey, was produced by the work group set up in co-operation with Aicarr to support the Technological Group of the 'Indoor' Technical and Scientific Committee of the Prevention Department of the
This paper presents the result of a research carried out on the valuation method of ductworks hygienic condition. Both the methodology and the results of the samplings carried out on the HVAC systems of ten hospitals are presented.
Intelligent buildings integrate ecological, economical and ergonomical aspects. The aim is the creation of a high application quality at a low energy consumption and CO2 emission.
Describes how engineers retrofitted a modern heating, ventilation and air conditioning (HVAC) system, controls and other energy saving modifications into a neoclassic 19th century building.
