LoginThis paper describes a set of experiments conducted in a three bedroom house in order to identify the leakage distribution of the building and the air flow rate through the on-purpose designed opening of the interior doors.

Whole-building pressurisation tests can quantify the air-leakiness of a building's external envelope. The resulting information can be used in assessing the quality of the building fabric.
VAV - air conditioning system makes it possible to control indoor conditions even when the heat loads are changing. But this is possible only when each part of the system works as it is intended to work.
A method is being developed for visualization of air flow with application to the indoor problems of heating, ventilating and air conditioning.
A comparison of different methods of calculating interzonal airflows by multiple tracer gas decay tests. | 1989 | English
Measurement methods based upon multiple tracer gas techniques have become an established branch of the study of air infiltration and interzonal air movements.
This paper gives an overview of air infiltration and ventilation developments and trends in Norway. The paper is divided into an infiltration part and aventilation part.
Public policy considerations and the development of a code for the control of radon in residences. | 1989 | English
Building codes that address radon control in residential buildings are a relatively new development in the larger trend toward increased efforts to understand and control indoor air quality.
Displacement flow systems are becoming popular, especially in Scandinavia, for comfort ventilation.
Buoyancy-driven air flow in a closed half scale stairwell model: velocity and temperature measurements. | 1989 | English
This paper describes an experimental study of the buoyancy-driven flow and the associated energy transfer within a closed, halfscale stairwell model.
The IEA Annex 18 Demand Controlled Ventilating Systems-(DCV-Systems) with 9 participants are just in the middle of the work.
What does the designer of a future energy-efficient building ask of the air flow specialist? - Static predictions of air flow patterns and optimization of thermal comfort and indoor air quality at design conditions will not be enough for him.
Annex 14 -Condensation and Energy- started in April 1987, with a take of meeting in Utrecht, The Netherlands. The annex itself was born after a moisture-workshop in September 1985 at the Laboratory of Building Physics, KULeuven, Belgium.
Tracer gas techniques have become widely used to measure the ventilation rates in buildings.
