The paper describes the main results from a research project performed by "The Mobile Laboratory of Indoor Climate Measurements" one of the five mobile laboratories of the Institute. The aim of the project was to investigate if undesirable consequences occurred in the indoor climate when using an energy saving method consisting of reducing the mechanical exhaust from the "wet rooms" to app. 40 per cent of the normal performance during 12 hours of day and night.
Describes a method used for measuring the local air tightness of sections of buildings. Notes its superiority to a previous system developed by Siitonen V. in 1982. Illustrates the device schematically and explains its operation.
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.
