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.
Recently, in the Polish building sector, there has been a conflict between ventilation techniques and a strong tendency toward increasing building airtightness.
The air conditioning of large non-domestic buildings is becoming an increasing trend, even in moderately mild climatic zones. This is often needed to avoid overheating that results from high internal heat gains and solar radiation.
In order to study the energy performance of a school building incorporating a hybrid ventilation system in Grong, Norway, a detailed field experiment was carried out.
‘Supply air’ windows are designed with an air gap between the inner panes of glass that is used as the incoming air path for room ventilation; air is pre-warmed within the window and thereby avoids the sensation of draughts.
A ventilation system integrating a buried-pipe technique with multi-purpose windows | 2005 | English
This paper introduces a ventilation system that combines buried-pipes with multi-purpose windows with the aim of finding an energy efficient, environment-protecting and low-cost way to improve the indoor environment.
The paper presents a procedure to estimate natural ventilation flow rates through buildings.
Human thermal comfort is influenced by psychological as well as physiological factors. Several comfort indices, such as PMV, PPD, TSENS, ET*, DISC, and SET* (see nomenclature) have been developed.
Fans are used in many industrial, building and household applications, especially for ventilation, and are often considered as particularly noisy components.
When an obstruction is present in a ventilation ductwork, the noise level may be considerably higher than the level measured without the obstruction.
Conventional methods of multi-zone airflow analysis ignore mechanical energy conservation in forming the system equations governing building airflows.
Among the tools which serve to predict heat and mass transfer in a mechanically ventilated room, CFD is increasingly used. However, this type of tool needs a correct description of the boundary conditions, especially concerning the air inlet.
Cross-ventilation is a mechanism using the pressure difference between the outdoor environment and indoor space to provide an energy-saving method for ventilation design.
Functional availability is used to quantify the probability of a system’s capability both to be in an
This paper describes a concept of probability-based design and its application in the field of ventilation.
The purpose of this research was to assess the performance of air infiltration or naturally driven ventilation, the corresponding energy consumption and indoor contaminant level for residential buildings in Harbin, a typical city in the severe col
The cooling effect of indoor air movement from circulator fans has been discounted in many strategies for increased energy efficiency.
The amount of energy used to heat and cool buildings is a significant concern that impacts on issues from national policies to personal desires of cost and comfort.
With the exception of a few analyses of the impacts of ASHRAE Standard 62-89 and energy use in specific buildings, the energy use in commercial building due to infiltration and ventilation flows has received little attention.
Natural night ventilation is an energy efficient way to improve thermal summer comfort. Coupled thermal and ventilation simulation tools predict the performances.
