The aim of the present study is to measure the possible health effects among tenants after certain characteristic energy conservation measures had been taken in their dwellings. Changes in comfort are also included. It is part of a number of projects on subjects such as indoor pollutant source control and changes in house dust mite populations related to moisture changes in retrofitted dwellings.
Retrofitting for air infiltration is undertaken for two principal reasons, to provide greater comfort and to save energy. Qualitative and quantitative measurement of air penetration is an essential prerequisite for planning anefficient retrofit for air infiltration. Describes methods of measurement with two examples of single family houses in sheltered and exposed locations.
Indoor air quality sampling strategies and analytical techniques have changed significantly in the past ten years. The changes reflect both the shifts in study objectives and the development of new forms of instrumentation. Toillustrate these trends, this paper describes early field techniques for measuring indoor air quality using a heavily instrumented mobile laboratory that is suitable for measuring one building intensively for up to four weeks.The style of measurement now is complemented by large field survey projects using passive samplers as the dominant instrumentation.
A survey of retrofitting possibilities for the amateur. Air infiltration, air quality, insulation and heat flow are described simply. Detailed examples are given of retrofitted houses. Various products available in Canada are listed. Concentrates on vapour barrier details and external retrofits and refers mainly to timber-framed houses.
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
A table is given which compares the performance, construction and function of the various types of window treatment. Aspects covered include sun control, thermal insulation, infiltration barrier, security and privacy, control by static, movab
Describes methods of predicting concentration levels of indoor air pollution in a variety of residences by using residence air infiltration rates, residence volumes, and source terms, and by making assumptions about occupant lifestyle and poll
The use of urea formaldehyde resins in Canadian houses, the mechanism of formaldehyde releases, health effects, toxicity, carginogenicity, allergic reactions and standards for ventilation are discussed.
In large areas of the Swiss Alps, the high radium content of rocks and soil, which results in high source terms for radon from the ground, may produce considerable indoor levels of radon in dwellings with low air infiltration. During the winter
The prospective study included two groups, a study group, which had retrofitting of their flats, and a control group not exposed to environmental changes in their homes. The results clearly demonstrated a number of positive effects of the replac
