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.
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.
Coupled air flow and heat conduction model for mechanically ventilated foundations. | 1989 | English
Rising moisture from the ground has caused quite a lot of damage on foundations of Swedish buildings. It is in some constructions possible to prevent this by mechanical ventilation below the floor or below the concrete slab.
Development of a microprocessor-controlled tracer gas system and measurement of ventilation in a scale model. | 1989 | English
This paper describes the development of a microprocessor-controlled tracer gas system which is capable of collecting a large number of tracer gas samples at short or long intervals.
France is one of the European countries where ventilation has the most advanced regulation.
Canadian research into residential ventilation and combustion venting revealed that the installed performance of exhaust equipment, ducting passages, and site-built chimneys was largely unknown.
Comparison of air infiltration rate and air leakage tests under reductive sealing for an industrial building. | 1989 | English
The paper compares air infiltration rate measurements with air leakage measurements in a modem industrial building.
A demand controlled air ductwork should be so dimensioned that the flow controllers have good flow and acoustical operation conditions.
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.
The IEA Annex 18 Demand Controlled Ventilating Systems-(DCV-Systems) with 9 participants are just in the middle of the work.
