LoginThe multi-storey blocks which constitute the main type of building in Greek urban environments, have certain common characteristics.
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.
19 university students were asked about their thermal comfort while attending ordinary lessons in a displacement ventilated test room of typical classroom size. Two different ceiling heights were tested.
Ventilation requirements for vehicular tunnels in the Hong Kong Special Administrative Region are discussed.
Indoor environment required for kitchens in a big hotel in Hong Kong wa described. Local regulations and design guides for ventilation systems in kitchen including exhausts were briefly reviewed.
Features of natural wind and artificial airflow are related to human thermal sensation. Based on the existing records of natural wind and artificial air movement, their turbulent intensity of velocity fluctuation, energy spectra.
Researches into natural ventilation characteristics of courtyard buildings have been carried out extensively in climates very different from tropical climate.
The effects on pressure loss of the separation and orientation of closely coupled duct fittings in RVAC systems were investigated using computational fluid dynamics to analyse the pressure distribution in a system containing two 90° bends in two c
Pressure testing techniques have long been used in the laboratory on building components such as windows, for example, to ensure that rain will not penetrate them under windy conditions.
Because of the lack of valid information regarding the influence of bends on the thermal and hydraulic performance of flues, a series of preliminary experiments were conducted using a full-scale Perspex rig.
Air movement can provide desirable cooling in "warm" conditions, but it can also cause discomfort.
Most indoor airflows are mixed convection. In order to simulate mixed convection accurately and efficiently, this paper uses a two-layer turbulence model.
An equation is developed for predicting the combined effect of naturally and mechanically induced air flows in buildings and solved by a combination of analytical and iterative methods.
In a recent survey of quantity surveyors, most believed that energy-efficient buildings are more expensive to build than conventional ones. But it isn't necessarily so by any means.
Efficient control of ventilation systems needs information on indoor air pollutant concentration. But most of the time, the pollutant concentration is not measured.
We analyzed 1994 sick leave for 3,720 hourly employees of a large Massachusetts manufacturer, in 40 buildings with 115 independently ventilated work areas. Corporate records identified building characteristics and IEQ complaints.
Perceived air quality, Sick Building Syndrome (SBS) symptoms and productivity were studied in a normally furnished office space (108 m3) ventilated with an outdoor airflow of 3, 10 or 30 L/s per person, corresponding to an air change rate of 0.6,
