A field study was carried out to evaluate the effectiveness of air leakage sealing techniques for reducing air infiltration in houses. Presealing and postsealing air leakage tests were performed upon 82 single detached houses inWinnipeg or southern Manitoba. All houses were placed under a negative pressure, and leakage sites were identified using smoke pencils. Windows and doors were weather-stripped and other unintentional openings caulked and sealed using specified materials and techniques.
This paper reports the findings from tests undertaken in an untight, two-storey, brick-built detached test house. Different ventilation schemes were in use: natural ventilation and mechanical ventilation (both extract and balanced ventilation).
The Linford project involved designing, building and monitoring 8 low energy passive solar houses. The houses were insulated to current Danish Regulation standards. Seven occupied and 1 unoccupied test house were monitored over two years.
Describes a five month study which measured radon concentration, air exchange (ventilation) rate, weather and radon source parameters in a house near Chicago. Factors influencing radon entry rate were investigated. Discusses the measurements presented, noting some patterns in the data which are hard to explain. Applies two models for radon entry rate to high and low airborne alpha activity at the sump.
The Linford project involved the design, construction and monitoring of 8 low energy houses in Milton Keynes. The houses were insulated to current Danish Regulation standards and incorporated several passive solar features. Seven occupied and
