LoginResults of air quality measurements are presented for a group of low-leakage houses located in Saskatoon, Saskatchewan. A total of 46 houses were tested for formaldehyde, nitrogen dioxide, radon, and humidity levels.
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.
Spatio-temporal measurements of a fluctuating pressure field acting on the side faces of a square prism of finite height in boundary-layer flows are presented for a zero degree angle of attack. Two typical neutral atmospheric flow conditions
During the last fifteen years Urea-Formaldehyde (UF) bonded particle board, medium density fiberboard and plywood have replaced whole wood as a construction material for flooring, wall panelling cabinet work and furniture. At the same time,
Due to better insulation and improved airtightness of doors and windows, the supply of fresh air entering a room has been greatly reduced.
A microprocessor-controlled, five point, all-teflon sequential air sampling system interfaced to a continuous formaldehyde analyser, the CEA model TGM 555 Air Monitor which uses the pararosaniline colorimetric method was used tomeasure the seaso
In response to employee complaints of upper respiratory and eye irritation, formaldehyde air sampling studies were conducted in two different office environments. The first was in a series of temporary modular buildings with construction simi
Formaldehyde concentrations and ventilation rates in Finnish housing were measured. Results are discussed with reference to the recommended minimum ventilation rate of 0.5 ach.
A matched pair of identical mobile homes, one supplied with electric heating and cooking utilities and the other with propane gas utilities, were used to evaluate, over a 14-month period, various factors which may affect indoor formaldehyde c
Results are given of the effect of ventilation rate, duct length and particle concentration on ion concentration under laboratory conditions. The effect of electrostatic fields is discussed.

The mould growth inside buildings merits study both in its own right as a natural phenomenon, and because it easily becomes airborne and might pose ahealth problem for certain individuals.
The employees in a large office in Trondheim were complaining about headache, tiredness, sickness, allergic reactions in eye and nose, dry skin, respiratory diseases etc., and as usual they believed that their inconvenience was due tothe ventilati
During the past few years it has become apparent that office environment problems have reached epidemic proportions.
Random samples of the workforces of an air conditioned and naturally ventilated building were interviewed using a doctor administered questionnaire.
An account is given of what the kindergarten staff wrongly believed caused the problems and what measures they carried out in an attempt to solve them. On the spot measurements showed however what the real main cause of the problems was.
Demonstrates that complaints by office staff about their physical environment are not necessarily caused by physical deficiencies.
Sedentary subjects occupied an environmental chamber (20-22 deg C, 35-50% RH) with low ventilation for 90 min. Judges (visitors) evaluated the odour of the chamber before and during, and after the 90-min period of occupancy.
A mobile laboratory has been constructed for the sensory analysis of air quality in the field. It is used as a human exposure chamber for prolonged exposure to low concentration pollutants, a generator chamber for air pollutants, and a pollut
The British Gas 'Autovent' system utilises the constant concentration technique and was developed for measuring ventilation rates in dwellings.
Pressurisation measurements were taken on 55 single family houses immediately before and after house tightening carried out as part of the Modular Retrofit Experiment (MRE) in New Jersey and New York. The data was reduced according totwo pres
