LoginThe classification of fume hoods in laboratories was conducted as a occupational protection part of risk assessment and management procedure. The fume hoods (n = 296) in laboratories were classified according to the observed face velocities.
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.
Unexpectedly, the indoor-outdoor pressure difference did not affect significantly the moisture content in different layers of two outer walls but the moisture content depended more strongly on the moisture content in outdoor.
Occupational hygiene conditions were examined in a welding shop after repairing the air-handling unit. Good indoor air quality was achieved with the new replacement ventilation system.
The rotating vane anemometer is an instrument that is widely used in the field by maintenance engineers and inspectors. The anemometer consists of a vane that is held at right angles to an airflow.
This paper presents the field experiments on the ventilation efficiency in an underground car park where high velocity fan-diffuser units were installed as shown in Photo 1.
This paper presents the results of the numerical simulation on the ventilation efficiency and the residual age of air by using CFD in the underground car park in which the field measurement was conducted as shown in a previous paper.
The paper deals with a three dimensional modelling of an experimental device realized in the Department of "Fisica Tecnica" of the University of Rome "La Sapienza" in cooperation with the Italian National Council of Researchers (CNR) in order to i
For a long time, scientific research has tried to establish the relationships between jet momentum and room velocities. The final breakthrough is still to come.
The literature review reported here is the first step in a larger 30 month-long project that will lay the groundwork for a residential commissioning industry in California focused on end-use energy and non- energy issues.
This paper describes the concept of using simulation as a tool for performance validation and energy analysis of HVAC systems.
From the skyscrapers of Manhattan to the Victorian houses of San Francisco and the shopping malls of Anytown, USA, buildings in the U.S. are remarkable for their variety.
Infiltration has traditionally been assumed to affect the energy load of a building by an amount equal to the product of the infiltration flow rate and the sensible enthalpy difference between inside and outside.
Duct leakage has been identified as a major source of energy loss in residential buildings. Most duct leakage occurs at the connections to registers, plenums or branches in the duct system.
Residential thermal distribution systems have significant energy and comfort implications due to losses from the distribution system in the form of leakage and conduction and poor distribution from room-to- room within the house.
Duct leakage has been identified as a major source of energy loss in residential buildings. Most duct leakage occurs at the connections to registers, plenums or branches in the duct system.
Ducts that carry heated or cooled air are often internally lined with fiberglass for acoustic control and thermal insulation.
Since the oil crisis of the seventies, the interest given to buildings physics, indoor climate and energy use has strongly increased.
This report presents background to and advice on methodologies for sensory evaluation of indoor air quality (IAQ).
Eighteen laboratories from 10 European countries participated in a comparison organized in the frame of the project VOCEM, a 2.5 year research collaboration among 4 research institutes and 4 industrial companies.
