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.
The work is concerned with measuring interzone air movement and investigating its effect on condensation in a traditionally built house. Air flows through a doorway between the lower and upper floors of a house were measured using a single tracer gas technique. To study the effect of temperature difference on interzone air flows, the lower floor of the house heated to various temperatures in the range of 18-350C using thermostatically controlled heaters.
