LoginThe concentration of carbon dioxide is used as an important index of indoor air quality representative of body odor or bioeffluents in Japan. In the construction field of Japan, there is a CO2 concentration standard of a thousand ppm or less.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Advancing energy efficient renovation solutions in buildings necessitate adopting high-insulation and airtightness to avoid heat loss through transmission and infiltration, which can result in overheating.
This study is designed to investigate the particulate matter removal efficiency of domestic air cleaner products and seeks to compare the particulate matter removal efficiency in a laboratory with that in real life.
Air Handling Unit (AHU), as a system for space heating and cooling is one of the most relevant causes of energy consumption in both residential and tertiary sector buildings.
Research shows that, despite compliance with building codes, residential ventilation systems do not deliver the requested air exchanges in the individual rooms. One of the reasons for this can be found in the way the building codes are composed.
In these three presentations, we review the origins and history of the Indoor Environmental Quality Global Alliance, AIVC’s view of the potential value of IEQ-GA, and directions it is taking and may take over the next decade.
Bio-based insulation materials represent an alternative to petro-based materials which may contribute to enhance buildings energy efficiency.
Occupants in non-industrial indoor environments should decide whether the indoor air quality is acceptable or not.
Air infiltration contributes to a heat loss typically representing up to one third of the heating demand of a building. The building airtightness, also quantified as air leakage, is the fundamental building property that impacts infiltration.
Recently, many studies have focused on the adsorption of pollutants as a method for improving indoor air quality.
In order to better address energy and indoor air quality issues, ventilation needs to become smarter.
The steady pressurisation method measures the building leakage in a range of high pressures, typically 10-60 Pa.
The proposed Annex should bring researchers and industry together to investigate the possible energy benefits by using gas phase air cleaners (partial substitute for ventilation) and establish procedures for improving indoor air quality or reduced
The research question of this report is “Is it possible to save energy by lowering the bedroom temperatures in winter”. In this paper first the literature on optimum sleeping temperatures is investigated.
As one of the founding partners of the IEQ-GA, the networking with other organisations within the global alliance is for AIVC very important.
This study deals with ventilation effects on measured and perceived indoor air quality (IAQ) in a demonstrator building where IAQ problems can occur.
Nowadays the improvement of building airtightness is an essential condition to achieve high energy performance of buildings. Therefore, there is a need to precisely describe and quantify buildings infiltrations.
The different methods for air flow rate measurement at air terminal devices are presented in this overview, such as van anemometer with a cone, small velocity probe (thermal probe or small vane anemometer), compensation method, etc.
Since the turn of the century, alarming data produced by the Indoor Air Quality Observatory (OQAI) have led to changes in French legislation, including, most notably, the introduction of compulsory labelling for construction products (decree no.
The air tightness of eight apartment buildings containing six to eleven units each on three or four floors has been tested with and without guard-zone pressure, i.e. with and without consideration of internal leakages.
