LoginAlthough most new houses in the Hokuriku region are equipped with air conditioners, some people living in farmhouses still feel that cross ventilation is more desirable. Comparative measurements were made between a new house and a farmhouse.
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.
As the sensible heat gain or cooling load are decreased by using thick thermal insulation in a building, the need for dehumidification increases. Especially in Kushiro, it is rather cool and humid in summer because of its foggy weather.
In order to design an environment-conscious house, it is desirable for summer indoor environment, to re-examine thermal conditions warmer than thermal comfort. The role of air movement is important, as it reduces the magnitude of discomfort.
Thick insulation in buildings offers great potential not only for decreasing cooling load but also for changing its calculation method, and for changing system design, operation or control of the system and the thermal environment of the room.
Applicability of CFD simulation to designing passive architectures was investigated using a passive solar room with a Trombe wall system inside it.
This paper presents a method for the dynamic numerical analysis in calculating the thermal environment in the atrium space of an institution for the elderly. The analysis is carried out and using BASIC.
A purpose of this research work is to study the environmental control in large indoor stadiums which utilize the natural ventilation. In these problems, effects by the airflow in and around the stadium should be analyzed.
Hokkaido is distinguished from the other island of Japan by having colder winters and cooler summers.
The concept of dynamic insulation, where cold air is drawn through porous insulation in a building envelope from outside to inside, thereby returning heat energy normally lost by conduction back into the interior of the building, has been studied
A passive solar house with sunspace made of reinforced concrete was constructed in Sendai, Japan in 1984. One year measurement of room temperatures were recorded. Also, detail measurements have been made during the summer and winter seasons.
Custom software to automatically administer questionnaires on computer screens was installed on computers in four open-plan offices. Five questions related to thermal comfort were presented twice per day for three months.
Entertainment clubs, nightclubs, theaters, restaurants, and coliseums, with their highly variable occupancy rate, are excellent candidates for demand-controlled ventilation.
This paper presents results of a project initiated by ASHRAE and the National Research Council of Canada.
In recent years, the atrium building has become commonplace. This paper explains the physical concepts of the steady fire, unsteady fire, zone fire model, and the fire plume that are the basis of atrium smoke management.
