LoginThis paper reports on the measurement results of ventilation rates in existing occupied houses in the northern region of Japan.
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.
The installed performance of cooking exhaust fans was evaluated through residential field experiments conducted on a sample of 15 devices varying in design and other characteristics.
Our lack of understanding of the health risks related to air pollutants exposure in buildings is perceived as a major deficiency, even though 80% of our time is spent indoors.
Energy use for fan operation can be significantly reduced by a 3-flanked approach:
In the light of global environmental problems, it is vital for buildings to conserve energy and make use of natural energies. Natural ventilation is one important method for achieving this.
Solar chimneys may provide enough ventilation to buildings when properly designed.
Recently, natural ventilation, which is a traditional cooling method in Japan, has become considered as the key method for cooling energy conservation.
A simulation study on the reduction of cooling loads by utilizing cross-ventilation was performed for a typically shaped house as defined by the Architectural Institute of Japan.
Designing for natural ventilation became permissible across an extended range of climate zones in 2004 with the incorporation of an adaptive model into ASHRAE's comfort standard (ASHRAE, 2004).
A working group for natural ventilation and cross-ventilation at the Architectural Institute of Japan (AIJ) was established in 2005 by researchers and designers with an interest in this topic.
An experimental study of the phenomenon of buoyancy driven natural ventilation through single-sided horizontal openings was performed in a full-scale laboratory test rig.
The prediction of indoor airflow is indispensable in evaluating the thermal sensation of occupants in a cross-ventilated space because enhanced heat loss due to the elevated convective heat transfer in the occupied zone is an essential part of imp
The reduction of carbon dioxide emission due to energy consumption in the household sector is an urgent task, worldwide. As a measure to respond to the task, a new regulation has just been enforced since April 2009, in Japan.
It is only comparatively recently, since the development of mechanical ventilation and refrigeration, that it has become possible to completely control the air quality and thermal environment inside buildings, irrespective of outdoor conditions.
In 2003 the new extension of the German Museum of Technology (Deutsches Technikmuseum, Berlin), which comprises around 12,000 m?? of exhibition space was completed as a low-energy building.
The identification of effective factors in the historical formation of architecture can help develop architecture and its various aspects (Mofidi, 2005). These factors may be classified in the groups of cultural, historical and climatic.
Natural ventilation is a well known strategy to improve indoor air velocity and reduce indoor temperature. It is the main criterion to achieve thermal comfort in terraced housing in Malaysia.
This paper presents a study aimed at evaluating the effectiveness of natural ventilation strategies used in government dwellings in the Egyptian desert climatic design region.
In a hot-humid climate, comfort ventilation involving air movement over the skin of the human body is a prime consideration for thermal comfort.
