LoginThermal and moisture performances of whole buildings are rather well understood today andvarious models exist for simulating those.
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.
An Integrated Zonal Model was developed to predict the three-dimensional airflow andcontaminant concentration distributions in a room. This model integrated a zonal model withmaterial emission/sink models.
VOCs concentration measurements in six hospitals were conducted, using passive samplers,in order to get outlined information on the IAQ.
The indoor environment is dynamic in nature, in particular, because of various emissionsources contributing with volatile organic compounds (VOCs).
The aim of this study is to help dimension the Sol Depressurization System against radon inexisting buildings.First, various remediation techniques implemented on existing buildings are comparedregarding the reduction of indoor radon concentration
Information is needed about the overall nature of the reasonably foreseeable exposures fromconsumer products, including intended exposures of chemicals released into the air by design(e.g.
This paper discusses research conducted to determine the status of indoor air chemicalpollution caused by formaldehyde in government offices in 2001.
Especially in new buildings we could find striking concentrations of MVOCs and we couldnot localize mould damage. We first supposed that some MVOC components are not specificfor microorganisms but normal VOC from new materials.
The aim of the study was to find out if the location of material has effect onmicrobiological findings. Material samples (n = 735) were taken from the buildingswith susceptible moisture damages.
Moisture-related indicators indoors are, e.g. visible mould and damp spots, condensation onthe inside of window panes, detached floor covering materials, flooding and bad odours.
In two school buildings, concentrations of viable fungal spores in air, material and insurface samples were high indicating moisture and mould damages. Microbesincluded numerous moisture indicating species (e.g.
During the research, air samples were taken by exposure of agar plates and taking smearsamples from the AC equipment. Sampling took place during the autumn because theconcentration of spores at that time reaches its peak.
Thirty classrooms in 10 schools in Shanghai, China, were investigated in winter. Dust wascollected by vacuum cleaning, analysed for ergosterol, muramic acid, and 3-hydroxy fattyacids (LPS) by tandem mass spectrometry (GC-MSMS).
In order to identify the effects of various kinds of floor materials and that of humidity on theconcentration of mite allergens in houses of allergy patients, measurements were carried outin two houses near Tokyo in August, November and December 2
A questionnaire on e.g. building characteristics including dampness, and allergic symptomsamong children from 8 918 homes was carried out in the year 2000.
The aim was to study changes of symptoms and signs in an office exposed to flooding fromheavy rain. All 18 workers participated in medical investigations in January 1998.
Japanese Building Maintenance Law defines that indoor humidity shall be maintained not lower than40%. But it is sometime very difficult to comply with the law. Indoor air humidifies in office buildingsmostly below 40% especially in wintertime.
Development of a performance indicator for mould growth risk avoidance in buildings | 2003 | English
Microbial growth has been known as one of the major problems related to IAQ inresidential and commercial buildings.
Microclimates in moisture chambers and environment in houses were evaluated using afungal index. The index was calculated from the growth rate of a sensor fungus in a test piece,fungal detector, during an exposure period to the test environment.
A novel indoor air purification technology using ions generated by discharge plasma hasbeen developed.
