LoginThe objectives of this study are to reproduce in the laboratory different levels of cleanliness innon-porous ducts of HVAC systems, to compare a new method for sampling surface dust inducts with those methods cited in the literature, to compare th
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.
The published REHVA guidebook provides comprehensive uptodateinformation aboutdesign features, criteria for cleanliness, inspection and cleaning instructions of ventilationsystems.
Man made mineral fibers (MMMFs) that can cause irritation in upper respiratory tract, eyesand skin, can be emitted to indoor air from the HVAC system.
The sources of man-made mineral fibres (MMMFs) settled on furniture surfaces and in supply air were determined in an office building. The impact of renovation on indoor air and the perception of air quality by the occupants were studied.
Since the study by P.O Fanger (1988) [1] we know that the Heating Ventilating and AirConditioning (HVAC) system could be responsible for a large amount of indoor air pollutionand Sick Build Syndrome (SBS).
Cleaning ventilation system ductwork has been a topic of controversy for several years. Guidance documents are available for duct cleaning, but uniformity in application of remediation and cleaning methods is inconsistent in many cases.
The effectiveness of UV radiation lamps in order to reduce fungal contamination of HEPA filters, to extend filter efficacy and to reduce maintenance costs, is experimentally studied by means of a dedicated air conditioning unit.
Entrance of snow into the HVACsystemsis common problem in the arcticandsubarcticclimates and may cause moistening or wetting of filters and outdoor air chambers whichpromotes microbe growth.
This paper describes a methodology for improving individual thermal comfort in an officebuilding without increasing energy consumption.
Thermal comfort studies and standards show that room temperatures should be higher in thewarmer season than in the colder season. An interview survey with a sample size of 3,094people was performed in Finland.
This study investigated on a subject’s thermal sensation and use of a “Cool Chair” in two actual warm offices.
Subjective experiments were conducted in a climate chamber to evaluate subjective thermal
Physiological parameters measured by an embedded body sensor system were demonstratedto respond to changes of the air temperature in an office environment.
Subjective experiments were carried out in a climate chamber using 16 Japanese subjects ofboth genders, in order to evaluate human comfort at very low humidity. Two levels ofabsolute humidity were set, 2.0 g/kg(DA) and 10.0 g/kg(DA).
This paper presents the findings of a short-term monitoring exercise and questionnaire surveyto assess the thermal comfort conditions actually being achieved in 6 Iranian Office buildings.The findings of the questionnaire and monitoring are compar
Energy efficient behaviour was studied by a questionnaire addressing office workersaltogether in 34 office buildings in Finland, Sweden, the Netherlands, France and Italy.
Currently, numerical simulation research on indoor air and human thermal comfort usuallyfocuses on the air-conditioning room in summer.
Concerns about energy efficiency, has brought new constructive trends researches.
The impacts of indoor thermal environment on body physiology have been carried on for four years (2003-2007) in laboratory in Chongqing, a typical city located in hot-summer and cold-winter region in China.
The occupants of hospitals like other buildings have widely differing thermal comfortrequirements due to their different levels of clothing and metabolism.
