LoginThe relationship between outside air ventilation rate and indoor VOC concentrations was studied through measurements in an office building (the call center of a health maintenance organization - 4600 m2 - 290 persons).
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.
Perceived air quality and sensory pollution loads were measured in 6 office buildings in Denmark with a panel of 43 subjets on a normal weekday and on a weekend. Results are presented and discussed.
30 human subjects were exposed to simulated office conditions to study perceived air quality and sick building symptoms. The sensory pollution load of personal computers was found to be 3 olf each.
This study investigated if low air temperature, which is known to improve the perception of air quality, also can reduce the intensity of some SBS symptoms.
A simple method was used to assess odor intensity in indoor environments by a trained panel. Reliable results were obtained.
Three offices ventilated with charcoal filtered outdoor air were investigated with different air change rates, ozone level and limonene, using the perception of a sensory panel.
The aim of a study is to determine if on site, in a call-centre of 4600 m2, a correlation can be found between ventilation rate and performance of worker.
The study is a review of 600 articles to determine if indoor environments does influence student performance at school. The study has been extended to other categories (laboratories, offices).
In a building with two parts, one with bad indoor air quality, workers have been moved around from one to another and absenteeism rate and causes have been monitored.
To increase our understanding of the olfactory and trigeminal (i.e., sensory irritation) impact of chemical mixtures we have studied the binary mixture butyl acetate/toluene.
A building energy similation code (ACCURACY) was used to compare indoor humidity in an office room in a hot and humid climate (Hong Kong weather condiitons) equipped either with a conventional constant volume all air system or with a chilled ceili
This paper presents an analysis of air-to-air total heat exchangers (heat and mass transfer) built up using moisture permeable paper (but impermeable to air molecules).
This paper analyses through CFD simulation results the removal effectiveness in an office cooled by a chilled ceiling combined with either mixing or displacement ventilation.
Numerical simulation (CFD code) was used to optimise the design of the ventilation system of a large underground bus terminal complex near Seoul (Korea).
A questionnaire about the perception by HVAC systems designers of indoor air quality problems, already used in the USA in 1993 on a group of 60 designers, was submitted to 32 Polish HVAC designers. Results of both surveys are compared.
A big airport hangar for planes (177x37x92 m) was studied using CFD in cold season conditions. Without nozzle jets for air supply, severe temperature stratification occurs.
Fiberglass duct interior liners with and without biocides were submitted in an environmental chamber during 15 days to high air humidities, moisture and nutrient.
Sixty pubs were investigated in the UK to measure environmental tobacco smoke (ETS) concentrations in smoking and non-smoking areas. The ETS sampling equipment is described.
The performance of two gaseous air cleaners in a single test room was measured for toluene. The effectiveness is between 82 and 94%. Numerical simulations were performed with CONTAMW software to predict indoor air quality.
A test protocol for the determination of fractional filtration efficiency of electrostatic precipitators was developed in order to determine the changes in efficiency of these appliances in real life, due to reduced corona discharge from the ioniz
